GPS stands for Global Positioning System and was initially designed to be used by the U.S. military and is operated by the U.S. Defense Department. This system consists of 24 satellites, these satellites are 12,000 miles above us, are constantly moving in a precise orbit, have an atomic clock, and are solar powered. They do have a battery backup so they will continue to run in the event of a solar eclipse, and each satellites has a small rocket booster to maintain their orbit. The first satellite was launched in 1978 and it wasn't until 1994 when there were a total of 24 satellites. Each satellite has a life expectancy of about 10 years, so new satellites are constantly being built and launched. Each satellite weighs about 2,000 pounds and is approximately 17 feet in width when the solar panels are extended. In the 1980s the GPS became available to the public, and although it is still maintain by the U.S. Defense Department there is no charge for its usage by the public.
These 24 satellites orbit the earth twice a day and continuously sends the location of the satellite. A GPS system can tell how far a satellite is away by comparing the time difference between the time a signal was transmitted and the time it was received, the longer it takes the signal to be received by a receiver, the farther away the satellite is. If a GPS is receiving signals from three satellites it can calculate latitude and longitude. Altitude can be determined if the GPS is receiving signals from four satellites.
GPS can be used for navigating your car through traffic day-to-day or tracking a fleet of vehicles. Not only can a driver use a GPS for directions the main office knows where that vehicle is and the speed of the vehicle. GPS can be used while on vacation for activities such as hiking, camping, or hunting. Is your passion fishing but get frustrated trying to find the fish? With a fish finder which uses both GPS technology and sonar you'll know exactly where to go to find those fish. GPS technology is also being used as a way to track your pet if he wanders off or to safeguard a pet from being stolen.
Another use for GPS is as a child finder with a receiver in a child's cell phone or wristwatch to ensure a child's safety. It can be used in a teenager's car in order to both know where they and how fast they are driving. This could also be used to keep track of someone who tends to 'roam' but is not capable enough to find there way back; i.e. someone with Alzheimer's disease.
As GPS technology improves, it uses will increase. Who knows where it will take us next?

GPS technology and child safety
Copyright 2006 Angela Carter
What parent has had that moment of fright when the child who was just at your side is gone? Usually the child has seen something of interest and just gone to investigate, or has gotten separated in a crowd, such as being at a carnival, and although it may only two seconds to locate your child, it feels like two years and when you do find them your heart is racing, your hands are shaking and you don't know whether to hug them or scold them.
The possibility of someone taking our child is a real fear every parent carries with them. Just pick up a newspaper or watch the evening news and reports of children being kidnapped or abducted are constant and the heartbreak of the parents is just so overwhelming. Now what if there was a technology that could find that child instantly?
GPS technology is now being used to help keep track of children and allow parents to know where their child is at all times. These devices are usually small enough to fit anywhere-backpack, pants or coat pocket, etc. and lightweight enough not to be burdensome. Some of these have pre-programmable buttons so the child can keep in touch with their parents or call for help if necessary.
These devices range from tracking devices that will beep until the child is found, to cell phones with GPS technology installed, to watches that if forcibly removed will automatically activate. There are even backpacks available with GPS technology installed. Some of these will activate if the child is too far away from the parent. And there is even one that is implanted in a shoe.
Of course the main problems with these are the child is going to lose them, or if the child is abducted they can easily be disposed of. I can envision the day when it will be possible to have a GPS transmitter implanted in a child via an injection or some other simple manner.
There are other concerns also. Are only children with parents who can afford this technology are going to benefit. Is this going to increase the number of lower class children, whose parents can't afford this new technology, being abducted? Will someone, such as a child molester or kidnapper, find a way to use a child's transmitter signal to locate the child? Also how are our children to adjust to the fact that they are constantly being monitored?
How secure are our children going to feel knowing that the world is so dangerous that their parents need to know where they are at all times? Are we stripping a part of their childhood away from them? Who doesn't remember, as a kid, going somewhere you knew your parents didn't want you to go, but as children we are adventurers, and if we got into trouble or got 'caught' being where we shouldn't be, we more than likely not only got punished but also learned a lesson. We grow and mature by making mistakes and learning from them, are we going to take part of this education away from our children? At what age do we stop? Do we continue to monitor them through their teen-age years? A time that can be the hardest time of any child's or parents life, it's a time where a teenager needs to mature and a parent needs to learn to 'let go' and allow the child to learn on their own-mistakes and all.
Although this technology has some very great qualities in the protection of our children, the possibility of abusing this technology must also be addressed. We all want our children to be safe, yet at the same time they must be allowed to grow to become functional adults.

Best Handheld Devices In The Market
They are here to make your life better and convenient. Yes! We are talking about the best of handheld devices that are available in the market. Let it be finding your way through the woods or storing your precious data, these devices can handle the job better than any other conventional way of doing so.
That is not all, this is done by a device that can easily fit in your palm and slide in your pocket. These new age tools have added an altogether new dimension to our lives and it is not an exaggeration that within the small period of time, they have made themselves irreplaceable.
Today, the PDA device or the digital organizer is an integral part of our day to day life not forgetting about the useful handheld GPS devices that helps us to find any location within few clicks.
Let's learn more about the best of these devices that are functional and have eased our lives to a great extent. The first that comes to mind is a PDA or Personal Digital Assistant. In a nutshell the PDA device can be called as a "smart" pocket computer.
The handheld PDA devices are completely functional devices that offer portable electronic productivity and entertainment that come in several sizes with varying capabilities. They range varies from basic devices typically used to look up appointments and phone numbers to more advanced units that play music and videos or connect you to the Web.
With the advance of technology, the most significant trend in the present time is the use of such devices for communication via wired or wireless networks. A handheld PDA device gives you the much sought after freedom to access important data without geographical limitations, and with convenience.
That is why the this device is very much popular among those who have to spend most time out of the office and carrying a laptop every time is not a possibility. In fact, considering some occasions, you will find that a PDA is more useful as it is handy and can be carried in the pocket. A handheld PDA is even more useful with some of its interesting features like handwriting recognition software, which makes using it convenient.
On the other hand, a handheld GPS device offers navigational help and is really handy for outdoor adventure like camping, hiking, mountain biking, etc. Although a handheld GPS device is meant to help you navigate with the help of a satellite, most of them slide down in your pocket and provide you with the essential features, which are useful for more than finding directions.
One of the features of this unit is the UTM grid data maps or local grid maps. Many of the handheld GPS devices have multi-parallel channels to ensure that several satellites are tracking you at one time rather than just one.

The advanced GPS System Posted By : Anne Tide
Many people are still wondering about the utility of the Vehicle Tracking System; they are still wondering about the way this system is likely to function when installed in their own cars but the only thing that they should know s the fact the they may rely on the signal that comes from the global positioning satellites because this signal is very accurate when it comes to locating their mobile property.
The satellites will use all the given formation in order to locate every person or mobile property; certain positions will thus be shown and the GPS System may help you find the right direction when traveling. The first item that is quite handy and that comes along with almost every type of tracking system is the touch screen monitor; this interface monitor will be used in order to receive the necessary driving directions.
The voice instructions are quite easy to understand and these voice prompts will reinforce all the directions that are to be displayed on the monitor. Most of the tracking systems will display the necessary map of the location and you will be able to see your present position right on this map. Even the route that you are going to take is likely to be highlighted because the tracking systems will use all the available information when it comes to a particular area in order to provide you with all the alternatives.
The best and even the shortest routes are going to be displayed on the monitor in order to help you notice all the railways crossing that will intersect your own roads. By displaying these crossing, the monitor will let you know that your travel is going to be compromised in case that you do not avoid these unnecessary crossing roads. Navigating the city will become easer because you will be accompanied by the voce instructions that will teach you everything you need to know about a particular area of the city.
The electronic voice will provide you with easy to understand and quite simple directions that are highly necessary when you are dealing with unknown zones. These simple directions re to be followed and you can even choose the type of voce that is going to recommend you the existing alternatives. You may choose a female or male voice but you should also be fully aware that these electronic devices can fail sometimes thanks to their electronic malfunctioning.
For instance, people may get lost or they may be even misdirected but these occurrences are quite rare. Therefore, you will have to add your common sense in order to complete all the electronic advices; you will have to make sure that you are directed in the right direction and you can try and verify the locations by your own. Common sense is always to be use in conjunction with the voice instructions in order to avoid getting lost.
The Vehicle Tracking System has been designed in order to help you navigate in the unfamiliar areas of different cities; this global positioning system will be mainly based on the signals that are received. These signals will be transformed and adapted to your current location thus providing the driver with the necessary information. The entire system is to be regarded as a sort of invisible network that can be highly efficient when it comes to protecting your mobile properties.
The tracking system will also allow you to communicate with your vehicles by using the email, cell pager and even via internet; most people have claimed that the existence of such tracking systems in their mobile properties is likely to provide them with a special peace of mind because they will not have to worry about the safety of their property anymore. They can fully rely on the information that comes from their tracking system on a constant basis because the reporting features are to be trusted.
When planning to purchase the GPS System, you will have to think about the features that are likely to work best in your own case. Therefore, you will have to think whether you need added bonuses or just a simple tracking system or not. For instance, you will have to pay attention to the size of the GPS unit in order for the system to be a portable one. You may also consider the price of this unit in order to make sure you can afford such a device for your car.

Your Options For Auto Navigational Systems
The following article lists some simple, informative tips that will help you have a better experience with auto navigation systems.
It is true that auto navigation systems installed by automakers look completely natural and integrated into the features of the vehicles we purchase. For that reason alone, many people opt to pay several times over what the system would have cost to have installed by someone other than the maker of the automobile. It is truly amazing how much of an impact aesthetics makes when it comes to purchasing your next dream car, or even your first dream car. The thing is, that even if the system doesn't seem to flow with the look of your car, there are very valid reasons for getting one in the first place and the safety and security that they provide travelers is very well worth the sacrifice of a few aesthetic features.
It isn't exactly necessary, however, to completely sacrifice aesthetics in order to have the safety and security that auto navigation systems provide. As a matter of fact, some of the most popular brands of these systems are actually installed to the car by use of suction cups rather than cutting into the dashboard or removing the ever so important stereo from your car, truck, or SUV. Keeping price conscious consumers in mind, manufacturers are offering many options well under the 500 dollar benchmark while also affording consumers the luxury (or lower price, however you decide to call it) of installing these devices themselves.
It is important to remember that not all GPS (global positioning satellite) devices are meant to assist in auto navigation and make your purchase according to your specific needs. When shopping for one of these devices it would be comparing apples to oranges to compare a tool that is widely used for activities such as geo caching, hiking, biking, or boating. Each of these will bring in different price tags while offering greatly varied features. You need a device that is meant for mapping directions if you plan to use your device or system for driving.
I try to keep pointing out the fact that not all GPS or auto navigation systems are created equal this is very important to remember. You run the risk of purchasing the wrong system without proper planning and thus having a bad overall experience. Even among systems designed specifically for the automobile that offer mapping and navigation assistance there are different types that will appeal to different needs and uses. There are three types of auto navigation systems. Those three types of systems include: Navigation systems that are designed to stand alone, handheld systems that suit multiple purposes, and systems that are designed to work with laptops, PCs, pocket PCs, and PDA systems.
So far, we've uncovered some interesting facts about auto navigation systems. You may decide that the following information is even more interesting.
Each of the types of auto navigation systems and devices offers different benefits and drawbacks. It is ultimately up to you to decide which will suit your needs most. The stand-alone systems are often the most popular choice and are excellent for those who need driving directions and nothing more. They offer a steady power supply, turn by turn direction (in many cases), the security of being there at all times (no worry about whether or not you remembered to actually bring it along), and verbal directions along with landmarks that should let you know you are on the right path. There is a reason that these are the most popular.
For those who want to take their navigational tools off road on occasion other devices might be much better suited to your needs. Handheld devices often require additional software in order to work well with door-to-door types of directions or regular driving directions, however, they offer portability for those who wish to go biking, hiking, or kayaking and need the confidence that directions and navigational tools can provide. For those who have laptops or PDAs, the software that is available for these provide an excellent service when it comes to navigation both on and off roads and the beaten path. The cost is offset greatly if you already own your laptop or PDA and well worth a little extra investment, particularly if you will use this particular tool on a regular basis.
As I've said before, there is no perfect navigational solution for everyone, but there are quite a few that are nearly perfect for all who will dare to use them.
Now you can understand why there's a growing interest in auto navigation systems. When people start looking for more information about auto navigation systems, you'll be in a position to meet their needs.

Tips You Can Use To Auto Gps System
After reading our article, you can impress your friends with the amazing amount of knowledge you have gained on this subject.
Imagine the next time you enroll a discussion about auto gps system. When you dawn sharing the fascinating auto gps system facts below, your friends will be absolutely amazed.
Global Positioning System (GPS) is a navigational aid originally urbanized for the military. The system simply receives signals. It is the practical technology that gives the GPS its versatility.
If you have ever worn map and compass, you will understand a little about how the GPS works. In order to find your thinking on a map, you want to have three points of reference. The intersecting line from the location points is where you are. Map and extent work uses triangulation (bearings), GPS uses trilateration (distances) to reckon location. Satellites orbiting the earth emit sole signals that can be customary by a GPS. The GPS software interprets the signal, identifying the satellite that it came from, where it was located, and the time that it took for the hint to attain the system. Once the receiver has both time and void it begins to verify position.
The second half of this article will help you to extend upon what you have learned in the first half.
Three satellites give the intersection sense and the fourth is worn to delay that the positioning is accurate. Accuracy depends ahead the synchronization of atomic clocks in the satellites with the regulator in the GPS system. though the regulator in the GPS is not atomic, utilizing the fourth satellite gives it that functionality as the interior regulator adjusts itself to amend any discrepancy discovered.
GPS has consumed far past its early military application. Drivers can find their way through city streets, long coldness trekkers use the technology to annoyed unfamiliar terrain, mariners and pilots use GPS enhanced data to annoyed the seas and skies.
In--vehicle GPS can be integrated into the car entertainment system or can be installed as a removable device. These systems want to tell the driver where he/she is and how to spread their destination. The information includes street directions desirable relevant skin along the way such as support stops, gas stations, points of interest, etc. Auto GPS uses voice orders so that the driver can concentrate on the road.
Hikers and trekkers use analogous technology, but typically without the inclusion of street systems on their devices. Mapping software defines the territory that the walker will encounter. The addict can pierce waypoints (points of reference) so they can restore with the same route. They can add points of benefit such as water sources, viable campsites, and other items of benefit on their trail. However, the portability demanded by hikers will also limit the functionality of the system as small screens mean that some detail will be lost.
See how greatly you can learn about auto gps system when you take a little time to read a well-researched article? Don't avoid out on the respite of this great information.
It is GPS technology that is worn to footprint individuals on home arrest, to track gone pets, stolen vehicles, and gone people. Small systems can be incorporated into pet collars and wristwatches. As long as the receiver is active, it can be found.
Marine and aviation GPS units are sophisticated and specialized. The principles complex are the same as any average system; the software is greatly more decidedly developed.
Any fisherman, who is with a fish finder on his boat, is with a GPS that is enhanced by sonar and tracking devices. Units have been urbanized for use on drift tubes also - as GPS technology advances, the systems become more and more compact and their uses more and more extensive.
If you are considering purchasing a GPS, make sure that it can be efficient easily. This is especially accurate if you buy a multi--function GPS or one that is worn where conditions change regularly. An in--vehicle GPS shortly loses its usefulness if it is not efficient as boulevard systems change.
Updates vary according to the method being used. They can come in CD/DVD post or as laptop downloads. The addict can hold maps special to the subject in which the GPS will be worn or a stretch of maps and routes. These are vacant from GPS software companies who will charge proportionally to the sophistication of the software.
GPS units vary in rate according to their usefulness. It is potential to buy units for fewer than one hundred dollars to units costing more than one thousand dollars. What your desires are will be a thing in the expense of your unit. If you are a backpacker then portability is a main consideration. If you are a trucker, you necessary to be able to find a transfer item as swiftly and conveniently as possible. suchlike ruse you go for, expense is usually related to quality. Buy the best you can afford.
Now you can be a poised expert on auto gps system. OK, perhaps not an expert. But you should have something to pass to the enter next time you adhere a discussion on auto gps system.
What you have learned while reading this informative article, is knowledge that you can keep with you for a lifetime.

Many people are still wondering about the utility of the Vehicle Tracking System; they are still wondering about the way this system is likely to function when installed in their own cars but the only thing that they should know s the fact the they may rely on the signal that comes from the global positioning satellites because this signal is very accurate when it comes to locating their mobile property.
The satellites will use all the given formation in order to locate every person or mobile property; certain positions will thus be shown and the GPS System may help you find the right direction when traveling. The first item that is quite handy and that comes along with almost every type of tracking system is the touch screen monitor; this interface monitor will be used in order to receive the necessary driving directions.
The voice instructions are quite easy to understand and these voice prompts will reinforce all the directions that are to be displayed on the monitor. Most of the tracking systems will display the necessary map of the location and you will be able to see your present position right on this map. Even the route that you are going to take is likely to be highlighted because the tracking systems will use all the available information when it comes to a particular area in order to provide you with all the alternatives.
The best and even the shortest routes are going to be displayed on the monitor in order to help you notice all the railways crossing that will intersect your own roads. By displaying these crossing, the monitor will let you know that your travel is going to be compromised in case that you do not avoid these unnecessary crossing roads. Navigating the city will become easer because you will be accompanied by the voce instructions that will teach you everything you need to know about a particular area of the city.
The electronic voice will provide you with easy to understand and quite simple directions that are highly necessary when you are dealing with unknown zones. These simple directions re to be followed and you can even choose the type of voce that is going to recommend you the existing alternatives. You may choose a female or male voice but you should also be fully aware that these electronic devices can fail sometimes thanks to their electronic malfunctioning.
For instance, people may get lost or they may be even misdirected but these occurrences are quite rare. Therefore, you will have to add your common sense in order to complete all the electronic advices; you will have to make sure that you are directed in the right direction and you can try and verify the locations by your own. Common sense is always to be use in conjunction with the voice instructions in order to avoid getting lost.
The Vehicle Tracking System has been designed in order to help you navigate in the unfamiliar areas of different cities; this global positioning system will be mainly based on the signals that are received. These signals will be transformed and adapted to your current location thus providing the driver with the necessary information. The entire system is to be regarded as a sort of invisible network that can be highly efficient when it comes to protecting your mobile properties.
The tracking system will also allow you to communicate with your vehicles by using the email, cell pager and even via internet; most people have claimed that the existence of such tracking systems in their mobile properties is likely to provide them with a special peace of mind because they will not have to worry about the safety of their property anymore. They can fully rely on the information that comes from their tracking system on a constant basis because the reporting features are to be trusted.
When planning to purchase the GPS System, you will have to think about the features that are likely to work best in your own case. Therefore, you will have to think whether you need added bonuses or just a simple tracking system or not. For instance, you will have to pay attention to the size of the GPS unit in order for the system to be a portable one. You may also consider the price of this unit in order to make sure you can afford such a device for your car.

The GPS System is a navigational device that uses the computers and satellites in order to determine the longitude and latitude of all the receivers that are to be found on earth; this result is achieved by computing the current time difference from all the signals that are coming from various satellites in order to reach the receiver. The GPS System is to be regarded as the only system that is fully functional; the radio signals are used by the satellites in order to reach all the electronic receivers.
The satellites will thus be able to correctly locate the electronic receiver in order to get the correct and exact longitude, altitude and latitude of the receiver; every tracking system is likely to work around the ordinary clock without taking into account the weather conditions. These systems are designed in order to be fully functional because this type of signal is regarded as being a quite steady one that has improve its features along the way.
Every tracking system can actually pinpoint every receiver who is to be found on earth to almost 6 meters of his current location. The techniques that are being used in this case are coming from various types of tracking signals that have been affected by constant development and improvement. This constant development has resulted into a greater accuracy and the time reference will thus become extremely precise.
Some scientific experiments are also likely to take full advantage of these tracking systems as well. The GPS signal will come along with detailed information because this type of tracking is to be regarded as the perfect tool that is to be used throughout your entire life. You can actually benefit from this type of tracking in various ways when it comes to your daily routine; for instance, you can choose the Vehicle Tracking System in order to determine the exact hike you are going to take because this system is designed in order to steer you and your family by telling you the right way to go.
The system is very helpful when it comes to installing in your own car because this device can be considered as the perfect safety measure that may prevent your car from being stolen. Many cars will be equipped with the GPS System because their drivers are fully aware of all the opportunities that may come along when deciding to have this method installed in their personal cars. The tracking device will help you reach the wanted location by telling you the current position of your car and showing the right direction for you to go next.
The system can also show you the exact steps that are to be made in order to reach the desired location; you will also be safe when driving a car that is provided with the Vehicle Tracking System because the authorities may use the received data in order to track you down in an emergency case. The system s to be regarded as a genuine guideline that is to be used especially when you are not sure about the right direction to go; for instance, if you get lost in the middle of nature or storm, you are likely to want to know everything about your present location.
Therefore, a map is not likely to be very useful in such an emergency situation because it can be quite difficult for you to determine your exact location just by using the conventional map. The tracking system can do this for you because it can save you some future trouble when it comes to dealing with emergency situations. You will have to become familiar with the navigation systems in order to makes sure you will be safe in your future travels.
By using the tracking system, you will not have to use the conventional maps and compass anymore. On the contrary, you will be able to rely only on the tracking system to do this for you because all your present navigation needs can be handled in the appropriate manner without any worries. This tracking system is among the most efficient navigation devices and the present market is tempting all the potential buyers with this new tool. The system I so effective thanks to the fact that it relies on powerful satellites that are designed in order to locate the exact position of your car no matter where your vehicle is right in this moment.

Is a GPS useful on vacation?
Copyright 2006 Angela Carter
Vacations are times to relax and enjoy, not worry about finding your way around. Are you flying, or driving? Are you going somewhere that you know well or somewhere totally new? Are you renting a car if you're flying, or are you going to depend on taxis? If you are traveling by taxi do you know if a 'shortcut' the taxi driver suggests is really a shortcut or possibly are you being scammed to increase your rate. What are your plans once you get to your destination? Are you going backpacking, hunting, or fishing, or do planning a trip to a resort and plan on lying by the pool and just relaxing? Wouldn't it be nice not the have to worry about finding a location, or a good restaurant. Your visit would be much more enjoyable without this concern.
Is it possible that you will be off in your own airplane, with a GPS you can create your flight plans and get automatic calculations of headings, winds, time, and fuel or recalculate your heading. Are you driving or plan on renting a car once you get to your destination? Do you know the route well or is this a new adventure? Whether this is a trip that you frequently make or not a GPS can be indispensable. What if you get detoured due to an accident or road construction, what if you run into a large traffic jam do you need to sit and wait, or is there possibly another route you could take? Have you ever wanted to get off the beaten path and explore somewhere new but were afraid of getting lost? Wouldn't it be nice just to take off to somewhere new without the fear of getting lost? Do you plan on going fishing? Wouldn't it be nice to know where the fish are, so you can spend your time catching fish, instead of spending your whole vacation with the possibility of catching nothing?
Have you planned a trip to visit a foreign country but were afraid you have trouble getting around when street signs are in a different language? With a GPS you put in your destination and find the location that you would like to go to. There is also translation software which can be downloaded to your PCA.
Are you going backpacking, hiking or camping, or even plan on taking a bike ride, with a GPS you have the added security of knowing if you get lost you can find your way out. Is there an area you always wanted to explore, but was afraid of not finding your way back.
Vacations are too far apart (2-3 weeks a year?) and are planned, paid for and anxiously awaited for, to have to worry about getting lost. Whether you plan on lying by the beach or pool all day, you might want to find a certain restaurant or shop, or hiking through the forest a GPS can take the worry out of traveling and allow you to enjoy you're trip.

GPS technology and Mobile phones
Copyright 2006 Angela Carter
Imagine driving somewhere new, you're lost, unsure of where you are at, and the more you try to find your way out the more confused you get. Do you know how safe the area which you're in is, is it safe to get out of your car to ask for directions or are you risking being attacked? What if you are threatened or attacked, you have your cell phone, dial 9-1-1, but are unable to tell the operator how to find you. Imagine having an accident, or witnessing an accident, but you are unsure where you are, you call 9-1-1 but are unable to tell them where you are. Imagine becoming ill while in your car, you dial 9-1-1, but become unconscious before you can tell someone where you're at, how will anyone find you? Imagine being on a hike or bike ride when you suddenly realize you do not know where you are, how will you find your way back safely?
The U.S. FCC (Federal Communications Commission) has mandated the E911 (Enhanced 911) which requires that the location of any cell phone used to call 9-1-1 can be determined. This program is divided into two parts; the first requires carriers to report the telephone number of the caller and the location of the antenna that received the call. The second part requires carriers to be able to provide a more precise location. This will require that the manufacturers to install a GPS receiver in all cell phones. The benefit of this not only means that a cell phone can be quickly located, but that cell phones will have the ability to receive driving directions, and to be used as a hand-held GPS out of the car.
There are two ways that a GPS cell phone can be used to get driving directions. The first is to subscribe to a GPS navigation service, which is becoming available but is limited at this time. The second way is through use of a software program. Being able to subscribe to a navigation service has its disadvantages, if you are outside your coverage area your navigation functions won't work. Plus, not only do you have to purchase a GPS cell phone, you must also pay a set up fee and a monthly fee and be under a 3 month to one year contract.
The second way to get driving directions is to buy a software program, but you need to have a compatible cell phone. The programs and maps are on a memory card and there is no need to pay a monthly fee and since the maps are in the phone you are not dependent on a GPRS connection.
If you want to take your GPS cell phone with you while out of your car, not only are there integrated GPS cell phones, there are GPS add-ons available also.
Another advantage to having a cell phone with GPS technology is that parents know where their children are at any time (as long as they have the phone with them). Some carriers are offering this child location service as a 'peace of mind' feature. There is usually a monthly service charge for this service.

Popular GPS Watches For You
Technology has contributed a lot and is still contributing much to make our lives simple. It has eased communication to such an extent that we can be mobile and still stay in touch with each other. It is not only communication that is eased but a lot of other things which are more suitable to the changing needs of the fast paced individuals. One such change is in the way one used to find the directions.
Gone are the days when maps and compass were used to find directions. Although such techniques were useful but not accurate as the new age GPS system, which is the most accurate way of finding directions using a digital map. GPS or the Global Positioning System works with the help of satellites orbiting the earth and allows you to use it in many applications other than finding directions.
Although GPS is used with many applications, it has found an all new dimension when used with the wrist watch. Yes! A GPS device included in your wristwatch is not a dream but reality. With the wide use of GPS technology many tech savvy companies have tried and developed a wrist watch which is equipped with GPS. Now there are many companies which offer you a wrist watch with GPS technology.
The GPS wrist watches are meant for sportspersons and adventure buffs who want to spend more time in the open. This GPS watch is an expert navigator which can keep anyone on track in the mountains, forests, rivers or lakes without getting lost.
The GPS wrist watches are more or less like wrist computers and do have more than one set of functions. The only thing which you need to understand in these wrist watches is the limited size of the screen and restricted number of keys which means that the device must have different modes for displaying sufficient information on each topic on the screen.
The downside of such small screen is that you have to change modes al lot during complex operations. For example, if you want to access GPS and you happen to have the altitude mode on, you have to apply a fairly long sequence of keystrokes to go through the menu system. Some of the GPS watches do have as many as five different modes, which are time, altimeter/barometer, compass, GPS navigation and activity mode for measuring speed and distance.
The GPS watches are quite essential if you are planning an outdoor adventure. They are best to guide you to the location which you want to reach. They are also beneficial for trekking and mountaineering with the altimeter feature which keeps you updated on the height.
Some of the latest GPS watches also have an Activity mode, which shows you the speed, distance traveled, time from start and other values. Your trail is recorded in the device memory and this information can later be used for the Track Back function, or viewing the route at home via a PC.

How To Choose The Right GPS Tracking System
Copyright 2006 Alvin Toh
When it comes to purchasing a GPS tracking system, it is essential for you to make the right decisions. Although it is nice to see a beautiful unit displayed at your local department store and to just want to snatch it up, this can cause many problems for you in the long run. There are times when marketing gimmicks can make a standard product seems much more than it really is. If you are looking for quality and use of function from the unit, you must ensure that you make the right decision about the GPS tracking system that you purchase.
You can easily learn just about everything on GPS tracking system on the web. There are consumer reviews on GPS tracking system to assist you in comparing various options and choosing a suitable unit. The first thing to know is that the price tag does not necessarily reflect the value of the unit. When it comes to a GPS tracking unit, you will want to select the highest quality product rather than the one that has the biggest price tag on it. Now, that does not mean any unit with a low price is worth it either. In most cases, you are looking for a well-priced, high quality unit.
Instead of looking for the name brand that you have heard of, look at the features that the GPS tracking system has to offer. Does it have the right type of reception for your needs? Is it durable or waterproof? If you drop it into the lake when you are fishing, will it make it home still working? Can the GPS software be upgraded?
In addition, you need to consider the usability of the unit as well. Each and every one of the units on the market has a different look to it but each should be easy to use and benefit from. The ability to use GPS tracking units should not come too hard in this day and age. If you have used a computer, a PDA, a mobile phone, or other such electronics, you can easily move from one use to the next. If you have to pull out your user manual to determine how to navigate the menu, how likely are you to use it? Is it well-written, in good terminology that is easy for you to understand?
Some of the largest brand names in GPS tracking systems do cost a bit more but are well worth the price. You may have heard about Garmin or Navman. These are considered some of the best. But, you still have other options including Magellan, Mapopolis, AdvanTrack and Cobra GPS.
Once you have gathered the information that you need about these units and how well they fit within your life, you can move on to finding the best price. You must determine your needs, quality and usability of the product before you worry about the price. That is not to say that you should spend a small fortune on these products, but you do have to select the right product. Otherwise your money is wasted.
A GPS tracking unit is one of the best tools to have whether you're a sportsman, runner or even just someone who needs a bit of help getting from place to place. When you take the time to find the best product for your needs, you can be sure that it is money well spent.

The GPS Devices You Can Count On
A GPS or Global Positioning System is used to determine the user's current location, and the best route and directions for the destination. These positioning systems are now widely used in a variety of devices such as smart phones, automobile navigation systems, handheld devices, laptops and other such devices.
The working of this system is relatively simple to comprehend. In the working of a positioning system a GPS receiver calculates its position by measuring the distance between itself and three or more satellites. Since the signal travels at a known speed, measuring the time delay between transmission and reception of each GPS microwave signal gives the distance to each satellite, thus the calculations can be precise.
While doing this, the signals also carry information about the satellites' location. Thus by determining the position of, and distance to, at least three satellites, the receiver can compute its position using trilateration. The GPS receivers usually do not have perfectly accurate clocks and therefore track one or more additional satellites to correct the receiver's clock error. In such a way your location is taken out correctly and is displayed through the navigator.
In general, the receivers used in a typical positioning system are composed of an antenna, tuned to the frequencies transmitted by the satellites, receiver-processors, and a highly stable clock. Some of them also include a LCD display for providing location and speed information to the user.
The number of channels it can operate with and can monitor simultaneously describes the capacity of a reciver. Before a couple of years the numbers of channels in the receiver were limited to four or five, but has progressively increased over the years so that receivers typically have between twelve and twenty channels in the present scenario.
This system is now commonly used in a number of devices. One such use of the GPS system is in the recreational and sports activities. This allows the professionals, navigational and other important details using their device anywhere they could get the signals. That is why such devices are very popular among hikers, hunters, skiers, mountain bikers, and other such outdoor adventure buffs.
A GPS system is very essential in keeping the track of the location, and to find way to a specified destination, or know what direction and how fast you are traveling can utilize the benefits of the global positioning system or the GPS.
GPS is also widely used in the automobiles industry as well. There are some basic GPS applications that are used to provide emergency roadside assistance at the push of a button. It works by transmitting the current position of the user to a dispatch center.
Many systems that are more advanced and show your position on a navigation map are also available. These offer not one but man features apart from the navigational map; for instance, you can choose and select the best possible way to a desired location. You can even save your preferences in this type of advance systems.

In such a way your location is taken out correctly and is displayed through the navigator.
In general, the receivers used in a typical positioning system are composed of an antenna, tuned to the frequencies transmitted by the satellites, receiver-processors, and a highly stable clock. Some of them also include a LCD display for providing location and speed information to the user.
The number of channels it can operate with and can monitor simultaneously describes the capacity of a reciver. Before a couple of years the numbers of channels in the receiver were limited to four or five, but has progressively increased over the years so that receivers typically have between twelve and twenty channels in the present scenario.
This system is now commonly used in a number of devices. One such use of the GPS system is in the recreational and sports activities. This allows the professionals, navigational and other important details using their device anywhere they could get the signals. That is why such devices are very popular among hikers, hunters, skiers, mountain bikers, and other such outdoor adventure buffs.
A GPS system is very essential in keeping the track of the location, and to find way to a specified destination, or know what direction and how fast you are traveling can utilize the benefits of the global positioning system or the GPS.
GPS is also widely used in the automobiles industry as well. There are some basic GPS applications that are used to provide emergency roadside assistance at the push of a button. It works by transmitting the current position of the user to a dispatch center.
Many systems that are more advanced and show your position on a navigation map are also available. These offer not one but man features apart from the navigational map; for instance, you can choose and select the best possible way to a desired location. You can even save your preferences in this type of advance systems.

What is GPS Navigation
Global Positioning System (GPS) is a widely known system that uses satellite signals to trace the location and position of vehicles on earth. Formerly developed by the US Department of Defense, today it is a common feature in mobile devices and cars, which include a GPS navigation system to receive data that maps blocks of a city.
GPS navigation is a special feature providing you with 24-hour three-dimensional position information, including velocity, time, and traffic conditions in the area where your vehicle is located, being capable to go ahead on the road or any other place covered by the satellite-based positioning system.
This technology was first introduced to civilians through experimental Japanese cars. Today, it is a common feature available in GPS-enabled automobiles worldwide, although not all the cars include this unit. However, add in-car GPS Satellite Navigation is as easy as purchasing the hardware and very easy mapping software that provides information at street level accurately.
In-car navigation units have costs ranging from $350 to $1000 on average and include a series of functions such as pre-loaded maps, voice-guided directions, door-to-door navigation, and rechargeable battery. The advantage with these units is that they do not require a PC connection to work.
Although, if you are carrying a laptop or another compatible portable device, such as PDAs. PCMCIA GPS cards enable this feature in your system at a lower price, usually between $100 and $300. PCMCIA units have a lower power consumption and external active antenna with a connector port in addition to its high sensitive receivers.
When it comes to GPS navigation, remember that most smartphones and other wireless devices are also compatible with this technology. In fact, a large number of them include built-in GPS Navigation, although driving and consulting a handset is not as practical as having a GPS unit installed on your car.
New cars often come with GPS navigation units installed by the manufacturer. Other car models, old or new, do not include this benefit, but you can add it by purchasing the unit with your car dealer, at auto parts shops or other stores specialized in computer systems, or conveniently through the Internet.
Purchasing a GPS navigation unit requires a little research to become familiar with the different brands and functionality that each one offers to drivers. Among the top Car GPS navigation systems, the Garmin Nuvi 660 is one of a kind, but also one of the most expensive.
The Garmin Nuvi 660 provides you with all the navigation functions that you may require while driving anywhere in the world, but also PC and mobile device connectivity via Bluetooth, the reason this option is considered a good investment.
Other portable navigation systems are sold at more affordable prices, and depending on the level of mapping and functions their cost vary. Among the most popular GPS navigation units, we can mention the TomTom One, TomTom GO 910, the Magellan RoadMate 2200T, and the HP iPaq rx5900 Travel Companion.
Mentioning separately, the Navman F20 deserves to be noted since it is a very good portable GPS navigation unit, which is also one of the most affordable systems on the market, with prices ranging from $250 to $400 according to a popular online price comparison tool.
This device is also one of the most reliable, intuitive and accurate among others intended for first-time car buyers or people with no previous experience using GPS navigation systems.
There are many other GPS navigation systems and most of them are shipped with a vehicle mount, making it easier to take a peek at the map without the need to stop driving. As prices increase while browsing the different models, you will find that many costly units offer more benefits and durability, including voice guidance.
GPS Navigation is special but not a superfluous investment, if you do not need driving directions, the system is always useful to track wherever you are, find streets names, or avoid a traffic jam while saving you money and time.

The advanced GPS System Posted By : Anne Tide
Many people are still wondering about the utility of the Vehicle Tracking System; they are still wondering about the way this system is likely to function when installed in their own cars but the only thing that they should know s the fact the they may rely on the signal that comes from the global positioning satellites because this signal is very accurate when it comes to locating their mobile property.
The satellites will use all the given formation in order to locate every person or mobile property; certain positions will thus be shown and the GPS System may help you find the right direction when traveling. The first item that is quite handy and that comes along with almost every type of tracking system is the touch screen monitor; this interface monitor will be used in order to receive the necessary driving directions.
The voice instructions are quite easy to understand and these voice prompts will reinforce all the directions that are to be displayed on the monitor. Most of the tracking systems will display the necessary map of the location and you will be able to see your present position right on this map. Even the route that you are going to take is likely to be highlighted because the tracking systems will use all the available information when it comes to a particular area in order to provide you with all the alternatives.
The best and even the shortest routes are going to be displayed on the monitor in order to help you notice all the railways crossing that will intersect your own roads. By displaying these crossing, the monitor will let you know that your travel is going to be compromised in case that you do not avoid these unnecessary crossing roads. Navigating the city will become easer because you will be accompanied by the voce instructions that will teach you everything you need to know about a particular area of the city.
The electronic voice will provide you with easy to understand and quite simple directions that are highly necessary when you are dealing with unknown zones. These simple directions re to be followed and you can even choose the type of voce that is going to recommend you the existing alternatives. You may choose a female or male voice but you should also be fully aware that these electronic devices can fail sometimes thanks to their electronic malfunctioning.
For instance, people may get lost or they may be even misdirected but these occurrences are quite rare. Therefore, you will have to add your common sense in order to complete all the electronic advices; you will have to make sure that you are directed in the right direction and you can try and verify the locations by your own. Common sense is always to be use in conjunction with the voice instructions in order to avoid getting lost.
The Vehicle Tracking System has been designed in order to help you navigate in the unfamiliar areas of different cities; this global positioning system will be mainly based on the signals that are received. These signals will be transformed and adapted to your current location thus providing the driver with the necessary information. The entire system is to be regarded as a sort of invisible network that can be highly efficient when it comes to protecting your mobile properties.
The tracking system will also allow you to communicate with your vehicles by using the email, cell pager and even via internet; most people have claimed that the existence of such tracking systems in their mobile properties is likely to provide them with a special peace of mind because they will not have to worry about the safety of their property anymore. They can fully rely on the information that comes from their tracking system on a constant basis because the reporting features are to be trusted.
When planning to purchase the GPS System, you will have to think about the features that are likely to work best in your own case. Therefore, you will have to think whether you need added bonuses or just a simple tracking system or not. For instance, you will have to pay attention to the size of the GPS unit in order for the system to be a portable one. You may also consider the price of this unit in order to make sure you can afford such a device for your car.

The Vehicle Tracking System Posted By : Anne Tide
The GPS System is a navigational device that uses the computers and satellites in order to determine the longitude and latitude of all the receivers that are to be found on earth; this result is achieved by computing the current time difference from all the signals that are coming from various satellites in order to reach the receiver. The GPS System is to be regarded as the only system that is fully functional; the radio signals are used by the satellites in order to reach all the electronic receivers.
The satellites will thus be able to correctly locate the electronic receiver in order to get the correct and exact longitude, altitude and latitude of the receiver; every tracking system is likely to work around the ordinary clock without taking into account the weather conditions. These systems are designed in order to be fully functional because this type of signal is regarded as being a quite steady one that has improve its features along the way.
Every tracking system can actually pinpoint every receiver who is to be found on earth to almost 6 meters of his current location. The techniques that are being used in this case are coming from various types of tracking signals that have been affected by constant development and improvement. This constant development has resulted into a greater accuracy and the time reference will thus become extremely precise.
Some scientific experiments are also likely to take full advantage of these tracking systems as well. The GPS signal will come along with detailed information because this type of tracking is to be regarded as the perfect tool that is to be used throughout your entire life. You can actually benefit from this type of tracking in various ways when it comes to your daily routine; for instance, you can choose the Vehicle Tracking System in order to determine the exact hike you are going to take because this system is designed in order to steer you and your family by telling you the right way to go.
The system is very helpful when it comes to installing in your own car because this device can be considered as the perfect safety measure that may prevent your car from being stolen. Many cars will be equipped with the GPS System because their drivers are fully aware of all the opportunities that may come along when deciding to have this method installed in their personal cars. The tracking device will help you reach the wanted location by telling you the current position of your car and showing the right direction for you to go next.
The system can also show you the exact steps that are to be made in order to reach the desired location; you will also be safe when driving a car that is provided with the Vehicle Tracking System because the authorities may use the received data in order to track you down in an emergency case. The system s to be regarded as a genuine guideline that is to be used especially when you are not sure about the right direction to go; for instance, if you get lost in the middle of nature or storm, you are likely to want to know everything about your present location.
Therefore, a map is not likely to be very useful in such an emergency situation because it can be quite difficult for you to determine your exact location just by using the conventional map. The tracking system can do this for you because it can save you some future trouble when it comes to dealing with emergency situations. You will have to become familiar with the navigation systems in order to makes sure you will be safe in your future travels.
By using the tracking system, you will not have to use the conventional maps and compass anymore. On the contrary, you will be able to rely only on the tracking system to do this for you because all your present navigation needs can be handled in the appropriate manner without any worries. This tracking system is among the most efficient navigation devices and the present market is tempting all the potential buyers with this new tool. The system I so effective thanks to the fact that it relies on powerful satellites that are designed in order to locate the exact position of your car no matter where your vehicle is right in this moment.
The tracking system is widely spread and people should get accustomed to using this powerful navigation tool in order to provide themselves with extra safety measures; the average person may actually take full advantage of the Vehicle Tracking System because its features are easy to install and use.

Popular GSP Devices Posted By : Eugene Brenner
The global positioning system (GPS) was developed by the US Department of Defense and is officially known as NAVSTAR GPS. Initially, the global positioning system was available only to the US military and government, but after a period of time the system was made available for commercial use. Today, GPS is used by people from all walks of life and advances in technology have made possible integration of GPS receivers into all types of handheld devices, even modern day cell phones come equipped with GPS receivers. To better understand GPS, it is important to understand how GPS works.
There are currently 27 NAVSTAR satellites orbiting the globe, only 24 of these satellites are currently in use (the remaining 3 are backups if any satellite fails). Each satellite is positioned at an altitude of 12,000 miles from the earth and makes two complete rotations every day. These satellites have been positioned so that, at any given time there are at least 4 satellites 'visible' in the sky. A GPS receiver uses a process called trilateration to calculate the exact position of a person.
To better understand the process of trilateration lets start with a simple example. Let's assume you are located at a point X on the planet, your GPS receiver is actively receiving signals from at least 3 GPS satellites at any given time. A GPS receiver calculates the exact position of a person by using the signal strength from each satellite to narrow down the position. Say there are three satellites A, B and C from which the GPS receiver is receiving signals. By using the distinct signals the GPS receiver calculates the distance of the three satellites from the earth as well as from each other. The final coordinate calculation is not a simple one and is a series of complex results, but the end result is that the GPS receiver can effectively pinpoint the exact location in terms of longitude and latitude.
What is equally impressive about GPS is that each NAVSTAR satellite is equipped with an atomic clock to synchronise it with other satellites. The GPS receiver constantly resets its clock to stay in sync with GPS satellites. So, not only does the GPS system give you your location, but it also gives you the most accurate time on the planet!
GPS might seem fool proof, but factors like the earth's atmosphere and heavy cloud cover actually put off the calculations of a GPS receiver. To make the readings even more accurate, a GPS receiver uses signals from a stationary GPS receiver station. A stationary GPS receiver station already knows its precise location, so a GPS receiver can utilize the signals from a receiver station to correct any errors. This technique of calculating coordinates is known as differential GPS and almost all commercial GPS receivers available in the US come equipped with differential GPS.
The leading GPS device manufacturer today is Garmin. Garmin has one of the most comprehensive ranges of GPS devices and also makes quality GPS navigation devices. To buy Garmin GPS devices visit www.outdoorsman-essentials.com.
How GPS navigation devices work
A traditional GPS device only calculates the co-ordinates in terms of latitude and longitude. Since differential GPS allows for pinpoint accuracy, it is now possible to display the exact location of a person on a map by juxtaposing the co-ordinates with known co-ordinates. GPS navigation devices today offer features like choosing the best route to a destination, detailed route maps, calculating the distance already travelled and also the popular 'bead crumb trail' that shows the exact path traversed. Contrary to popular belief, GPS navigation systems only have a limited number of maps stored into them, and additional maps have to be fed into the device's memory. If the GPS navigation system does not have a map it cannot offer more than just the GPS co-ordinates.

Compare Garmin GPS Systems Before You Buy
GPS and Garmin have become synonymous. They are the leading GPS manufacturer in the world today by a long way. They started out in 1989 and today they have sold millions of GPS receivers.
So how do we know which Garmin GPS device will be perfect for our needs? There are so many which makes it very difficult to decide. The Garmin Nuvi and StreetPilot are some of the most popular GPS devices on the planet. Lets take a look at some of the automobile GPS systems and compare the differences.
Garmin StreetPilot 340
The Garmin StreetPilot c340 has a big advantage over the c330. That advantage is text converted to speech. Instead of GPS saying, turn right in 50 meters, it will say, turn right at Glover Street. This feature helps a lot when you dont want to look down at the device to confirm the street name.
Another great feature of the c340 is that it can easily be upgraded with an optional FM traffic receiver. What this means is that live traffic information can be sent to your GPS device to warn you of construction work, accidents etc. The StreetPilot c340 can then show you the way around the traffic and guide you to your destination.
Garmin Nuvi 250
The Nuvi 250 is famous for its simplicity. It doesnt have the advanced options most of us never use. So many buyers waste money on GPS systems that have features they will never use. They could have saved a lot of money and at the same time satisfy all there needs with a cheaper GPS system. If youre not the hard core type then the Garmin Nuvi 250 will be the perfect match for you.
The Garmin Nuvi 250 comes with a 3.5 inch display, which is the standard among the entry level GPS devices. 3.5 inch display is a big enough screen to find your way with ease. You can also insert a SD card if you would like to load additional products and maps.
The only feature the Nuvi 250 doesnt have is the text to speech feature I explained with the Garmin StreetPilot c340. Things like Bluetooth, MP3 player, FM transmitter and widescreen is not available on the Garmin Nuvi 250 but many will agree that its not necessary. If Garmin decided to include text to speech it would have been the perfect GPS system at entry level but if that doesnt bother you it might just be the one for you.

Handheld GPS Systems Keep You In The Right Direction
When you are lost and you cannot find your way it is a good idea to have a GPS tracking system in your car, you will receive directions on how to get to the place you need to get to. Above the earth there are many satellites orbiting the earth that are continually communicating and providing information about where the vehicle is located on the earth.
GPS or Global Positioning System tracks your location by interpreting the data received from 3 or more satellites. Since the invention of the cell phone, cell phone companies are able to help the authorities for many years by triangulated the position of someones cell phone by using there signal and the cell towers. Many cars and trucks are able to record the location and speed of the vehicle and is able to transmit this information back to the office.
There are many different types of GPS tracking systems, and many companies are manufacturing them. There are so many different kinds of handheld GPS systems, one kind has a built in radio which allows you to communicate with each other but also allows you see the position of all the other people on your screen, this is good for hikers to keep in contact with each other. The governmental agency (FCC) has instructed GPS system providers to help with 911 calls for those people who are lost and need to be traced and tracked. The GPS systems are so advanced now it allows the proper authorities to track locations for 911 emergency calls; this is only allowed when there is an emergency and will not be used on a daily basis. Many automobiles are being equipped with passive GPS tracking, these system will record the location and the drivers speed, this information can be used later on for statistical information. A vehicle's location is updated at intervals of between 2 - 15 minutes.
There are many types of GPS vehicle tracking; wireless passive, cellular and satellite systems that can track in a real time basis. When talking about a cellular based system, these systems transmit the vehicles information over a land network every 5 minutes.
GPS vehicle tracking systems are more affordable and more popular than ever before, but do you need one. Many business are starting to use GPS systems that track their vehicles so they know where each vehicles it. Many car manufactures are including these GPS systems in their cars and trucks. GPS tracking systems are used by businesses in the service, transportation and manufacturing industries.
There are other types of GPS or global positioning systems can help give you peace of mind in knowing when your pet has crossed outside the safety zone of the backyard, or somewhere in your neighborhood. Many pet tracker system use GPS technology to keep track of your pets, these devices are so small they are able to fit into the pets collar. GPS tracking system do cost more depending on the brand name, but the features and functionality are well worth it.

All About GPS
What It Is and How It Works - For those who are unfamiliar with the term, GPS stands for Global Positioning System. It's a way of locating a receiver in three dimensional space anywhere on the Earth, and even in orbit about it, and it's probably one of the most important inventions of the 20th century. GPS can be used in so many varied ways that new technologies are constantly being developed and improved in order to take advantage of it. Now why is GPS so important and useful? First, we have to understand how it works.
In order for GPS to work, a network of satellites was placed into orbit around planet Earth. These satellites each broadcast a specific signal, which is received by inexpensive aerials and passed on to GPS devices where it is then decoded and used by dedicated software. The information is specific enough that the GPS software can identify the satellite, it's location in space, and calculate the time that the signal took to travel from the satellite to the GPS receiver. Using different signals from different satellites, the GPS software is able to calculate the position of the receiver.
Mapping It Out - Even getting the information about the receiver's location will be useless without something to compare it with. This is where the mapping comes in handy; thru this, GPS can analyze our location and maps out possible routes. In fact, it is often the mapping data which elevates the price of the GPS solution. It must be accurate and updated reasonably frequently.
Several kinds of maps are created for different users. Road users, for example, require that their mapping data contains accurate information about the road network in the region that they will be traveling in, but will not require detailed information about the lie of the land. Hikers, however, might require a more detailed map about the local terrain, water spots, and tracks or trails, but they won't need extensive information about the road systems. Marine users need very specific information relating to the sea bed, navigable channels, and other pieces of maritime data that enables them to navigate safely.
Fishermen also use marine GPS to locate themselves and track the movement of shoals of fish both in real time, and to predict where they will be the next day. In fact, cooperative fishing has become much easier with GPS, allowing boats to relay locations to each other while looking for the best fishing spots. There are also GPS devices called "fish finders", which combines GPS and sonar functions to track and store detailed fishing and maritime information.
Get Started with GPS - Consumers can avail of several GPS devices that are specifically designed for a variety of uses and functions. Sophisticated in-car GPS systems, which feature voice guiding, powerful dynamic route calculation, and the possibility to update the map from a CD, are now available. Rugged handheld GPS devices, like those from Garmin and Magellan, have a map inside and are usually used for outdoor activities. They generally do not have any road information, and leave the users to find their own way from A to B.
A more recent solution has appeared on the market which uses the power of a PDA to run the actual GPS software. A GPS receiver can be easily attached to these devices, so these tend to be the cheapest, easiest to use and most flexible solutions. Bluetooth technology has also started to make use of GPS, using a single PDA device wirelessly connected to several receivers.

In order for GPS to work, a network of satellites was placed into orbit around planet Earth. These satellites each broadcast a specific signal, which is received by inexpensive aerials and passed on to GPS devices where it is then decoded and used by dedicated software. The information is specific enough that the GPS software can identify the satellite, it's location in space, and calculate the time that the signal took to travel from the satellite to the GPS receiver. Using different signals from different satellites, the GPS software is able to calculate the position of the receiver.
Mapping It Out - Even getting the information about the receiver's location will be useless without something to compare it with. This is where the mapping comes in handy; thru this, GPS can analyze our location and maps out possible routes. In fact, it is often the mapping data which elevates the price of the GPS solution. It must be accurate and updated reasonably frequently.

How To Really Win The War On Terrorism
Tom Cruise cry's in the movie 'Lions for Lambs', Do you want to win the war on terror... Yes or No. The movie is good but really fluff in regards to how to really win the war on terrorism.
This article is about what major security holes that currently exist in America and finally what we need to do to really win the war on terrorism.
There are 11 Major Security Holes cited by security experts that are possible scenarios in the near future. They are found in the book by Clark Kent Ervin titled 'Open Target, Where America is Vunerable to Attack' published in 2006.
According to Mr. Ervin, the following areas need to be watched carefully for terrorist activities as there are many weak and vulnerable areas that could trigger another major terrorist attack.
Border Security
Aviation
Port Security
Mass Transit
Intelligence
Preparedness
The book is a chilling reminder that it's pretty obvious that the nation is still very unprepared to respond to another catastrophic terrorist attack. If terrorists had targeted the levees in New Orleans, the government's response would be have been no quicker and more effective than that of Hurricane Katrina. It is very important that every major city have a well devised evacuation plan.
The chain of command must be very clear. First responders must be able to communicate with each other and with state and federal officials. Drills and exercises must be conducted frequently. Lessons learned must lead to prompt corrective action.
After having said that we now present the Mobile Tactical Collaboration System (tm) by Ordia Solutions. The Mobile Tactical Collaboration System (tm) is enabling commanders to know where their operators are, their speed and direction of travel. Operators have an added sense of safety knowing their moves are being monitored by their command staff during high risk and high threat operations. The MTCS system gives a clear cut chain of command and allows the edge in a crisis situation.
Smaller than a set of keys, the AdvanTraq GPS Tracker which is a major component of the MTCS, can be affixed to an officer's gun belt or radio harness, or with extended battery, to a vehicle.
The Mobile Tactical Collaboration System; integrated with advanced personnel tracking system AdvanTraq GPS deliver visual tactical interoperable communication, common operating picture, and real-time command and control situational awareness to multi-jurisdictional and multidisciplinary federal, state and local security taskforce handling dignitary protection and critical infrastructure protection at the US Naval Academy for US President George W. Bush, Israeli Prime Minister Ehud Olmert, Palestinian President Mahmoud Abbas, Middle East Quartet Envoy Tony Blair, and dozens of other world leaders at Mideast Peace Conference.
The Annapolis Conference was designated a Special Event Activity Report (SEAR) Level 2 security special event, a Department of Homeland Security designation that assesses the availability of federal, state, and local law enforcement resources in combination with the perceived threat level to the event. The State Departments Bureau of Diplomatic Security was the lead federal law enforcement agency for the Conference and worked with a multi-jurisdictional taskforce that included the US Secret Service, FBI, US Marshals Service, ATF, US Coast Guard, Maryland State Police, Anne Arundel County Police, Annapolis Police, Prince George's County Police, Metropolitan DC Police, and other federal, state, and local agencies. The FBI contingent hosted Ordia Solutions Mobile Tactical Collaboration System throughout the conference.
Within minutes of their short MTCS orientation, several FBI operators began redrawing their sector of operation at the US Naval Academy grounds from the static, paper-based operational map they were handed to dynamic and interactive MTCS workspaces on their wireless mobile computers. AdvanTraq GPS units were assigned to several members of the taskforce both in mobile land units and aboard tactical response boats so they could be tracked in their security details inside and outside the security zone. One of the tactical team leaders was equipped with a one-pound OQO model 02, the world's smallest full-featured ultra-mobile handheld PC, displaying his MTCS workspace.
When report of a potential threat location came to the Interagency Command Center, a quick reaction team was dispatched to investigate, with one of the members equipped with an AdvanTraq GPS unit.
The QRTs approach and return was tracked by personnel from both the ICC and Tactical Operation Center, providing added security and personnel accountability for the operators, and real-time situational awareness for commanders and other senior leadership at division headquarters.
SWAT teams tested out the Mobile Tactical Collaboration System in field conditions, both in mobile land units and aboard our tactical response boat. To put it in a nutshell, the MTCS gave authorities command and control capability that Hollywood has attributed to law enforcement tactical units for many years, but in truth we are only now realizing.
The importance of knowing, in real time, exactly where all of SWAT forces are deployed in relation to the incident site(s), infrastructure, support elements, and each other, and being able to share that common operating picture in real time with the chain of command and other agencies was critical in preventing another terrorist attack.
Best of all, personnel could brief those who needed the information without having to physically meet each time there was a change or update. With the MTCS system you just provided them with a website address, username and password.
The MTCS is a quantum leap forward in Government agencies ability to monitor and brief operations up the chain and to other agency representatives to help prevent the next major terrorist attack.

The advanced GPS System Posted By : Anne Tide
Many people are still wondering about the utility of the Vehicle Tracking System; they are still wondering about the way this system is likely to function when installed in their own cars but the only thing that they should know s the fact the they may rely on the signal that comes from the global positioning satellites because this signal is very accurate when it comes to locating their mobile property.
The satellites will use all the given formation in order to locate every person or mobile property; certain positions will thus be shown and the GPS System may help you find the right direction when traveling. The first item that is quite handy and that comes along with almost every type of tracking system is the touch screen monitor; this interface monitor will be used in order to receive the necessary driving directions.
The voice instructions are quite easy to understand and these voice prompts will reinforce all the directions that are to be displayed on the monitor. Most of the tracking systems will display the necessary map of the location and you will be able to see your present position right on this map. Even the route that you are going to take is likely to be highlighted because the tracking systems will use all the available information when it comes to a particular area in order to provide you with all the alternatives.
The best and even the shortest routes are going to be displayed on the monitor in order to help you notice all the railways crossing that will intersect your own roads. By displaying these crossing, the monitor will let you know that your travel is going to be compromised in case that you do not avoid these unnecessary crossing roads. Navigating the city will become easer because you will be accompanied by the voce instructions that will teach you everything you need to know about a particular area of the city.
The electronic voice will provide you with easy to understand and quite simple directions that are highly necessary when you are dealing with unknown zones. These simple directions re to be followed and you can even choose the type of voce that is going to recommend you the existing alternatives. You may choose a female or male voice but you should also be fully aware that these electronic devices can fail sometimes thanks to their electronic malfunctioning.
For instance, people may get lost or they may be even misdirected but these occurrences are quite rare. Therefore, you will have to add your common sense in order to complete all the electronic advices; you will have to make sure that you are directed in the right direction and you can try and verify the locations by your own. Common sense is always to be use in conjunction with the voice instructions in order to avoid getting lost.
The Vehicle Tracking System has been designed in order to help you navigate in the unfamiliar areas of different cities; this global positioning system will be mainly based on the signals that are received. These signals will be transformed and adapted to your current location thus providing the driver with the necessary information. The entire system is to be regarded as a sort of invisible network that can be highly efficient when it comes to protecting your mobile properties.
The tracking system will also allow you to communicate with your vehicles by using the email, cell pager and even via internet; most people have claimed that the existence of such tracking systems in their mobile properties is likely to provide them with a special peace of mind because they will not have to worry about the safety of their property anymore. They can fully rely on the information that comes from their tracking system on a constant basis because the reporting features are to be trusted.
When planning to purchase the GPS System, you will have to think about the features that are likely to work best in your own case. Therefore, you will have to think whether you need added bonuses or just a simple tracking system or not. For instance, you will have to pay attention to the size of the GPS unit in order for the system to be a portable one. You may also consider the price of this unit in order to make sure you can afford such a device for your car.

The Vehicle Tracking System Posted By : Anne Tide
The GPS System is a navigational device that uses the computers and satellites in order to determine the longitude and latitude of all the receivers that are to be found on earth; this result is achieved by computing the current time difference from all the signals that are coming from various satellites in order to reach the receiver. The GPS System is to be regarded as the only system that is fully functional; the radio signals are used by the satellites in order to reach all the electronic receivers.
The satellites will thus be able to correctly locate the electronic receiver in order to get the correct and exact longitude, altitude and latitude of the receiver; every tracking system is likely to work around the ordinary clock without taking into account the weather conditions. These systems are designed in order to be fully functional because this type of signal is regarded as being a quite steady one that has improve its features along the way.
Every tracking system can actually pinpoint every receiver who is to be found on earth to almost 6 meters of his current location. The techniques that are being used in this case are coming from various types of tracking signals that have been affected by constant development and improvement. This constant development has resulted into a greater accuracy and the time reference will thus become extremely precise.
Some scientific experiments are also likely to take full advantage of these tracking systems as well. The GPS signal will come along with detailed information because this type of tracking is to be regarded as the perfect tool that is to be used throughout your entire life. You can actually benefit from this type of tracking in various ways when it comes to your daily routine; for instance, you can choose the Vehicle Tracking System in order to determine the exact hike you are going to take because this system is designed in order to steer you and your family by telling you the right way to go.
The system is very helpful when it comes to installing in your own car because this device can be considered as the perfect safety measure that may prevent your car from being stolen. Many cars will be equipped with the GPS System because their drivers are fully aware of all the opportunities that may come along when deciding to have this method installed in their personal cars. The tracking device will help you reach the wanted location by telling you the current position of your car and showing the right direction for you to go next.
The system can also show you the exact steps that are to be made in order to reach the desired location; you will also be safe when driving a car that is provided with the Vehicle Tracking System because the authorities may use the received data in order to track you down in an emergency case. The system s to be regarded as a genuine guideline that is to be used especially when you are not sure about the right direction to go; for instance, if you get lost in the middle of nature or storm, you are likely to want to know everything about your present location.
Therefore, a map is not likely to be very useful in such an emergency situation because it can be quite difficult for you to determine your exact location just by using the conventional map. The tracking system can do this for you because it can save you some future trouble when it comes to dealing with emergency situations. You will have to become familiar with the navigation systems in order to makes sure you will be safe in your future travels.
By using the tracking system, you will not have to use the conventional maps and compass anymore. On the contrary, you will be able to rely only on the tracking system to do this for you because all your present navigation needs can be handled in the appropriate manner without any worries. This tracking system is among the most efficient navigation devices and the present market is tempting all the potential buyers with this new tool. The system I so effective thanks to the fact that it relies on powerful satellites that are designed in order to locate the exact position of your car no matter where your vehicle is right in this moment.
The tracking system is widely spread and people should get accustomed to using this powerful navigation tool in order to provide themselves with extra safety measures; the average person may actually take full advantage of the Vehicle Tracking System because its features are easy to install and use.

Popular GSP Devices Posted By : Eugene Brenner
The global positioning system (GPS) was developed by the US Department of Defense and is officially known as NAVSTAR GPS. Initially, the global positioning system was available only to the US military and government, but after a period of time the system was made available for commercial use. Today, GPS is used by people from all walks of life and advances in technology have made possible integration of GPS receivers into all types of handheld devices, even modern day cell phones come equipped with GPS receivers. To better understand GPS, it is important to understand how GPS works.
There are currently 27 NAVSTAR satellites orbiting the globe, only 24 of these satellites are currently in use (the remaining 3 are backups if any satellite fails). Each satellite is positioned at an altitude of 12,000 miles from the earth and makes two complete rotations every day. These satellites have been positioned so that, at any given time there are at least 4 satellites 'visible' in the sky. A GPS receiver uses a process called trilateration to calculate the exact position of a person.
To better understand the process of trilateration lets start with a simple example. Let's assume you are located at a point X on the planet, your GPS receiver is actively receiving signals from at least 3 GPS satellites at any given time. A GPS receiver calculates the exact position of a person by using the signal strength from each satellite to narrow down the position. Say there are three satellites A, B and C from which the GPS receiver is receiving signals. By using the distinct signals the GPS receiver calculates the distance of the three satellites from the earth as well as from each other. The final coordinate calculation is not a simple one and is a series of complex results, but the end result is that the GPS receiver can effectively pinpoint the exact location in terms of longitude and latitude.
What is equally impressive about GPS is that each NAVSTAR satellite is equipped with an atomic clock to synchronise it with other satellites. The GPS receiver constantly resets its clock to stay in sync with GPS satellites. So, not only does the GPS system give you your location, but it also gives you the most accurate time on the planet!
GPS might seem fool proof, but factors like the earth's atmosphere and heavy cloud cover actually put off the calculations of a GPS receiver. To make the readings even more accurate, a GPS receiver uses signals from a stationary GPS receiver station. A stationary GPS receiver station already knows its precise location, so a GPS receiver can utilize the signals from a receiver station to correct any errors. This technique of calculating coordinates is known as differential GPS and almost all commercial GPS receivers available in the US come equipped with differential GPS.
The leading GPS device manufacturer today is Garmin. Garmin has one of the most comprehensive ranges of GPS devices and also makes quality GPS navigation devices. To buy Garmin GPS devices visit www.outdoorsman-essentials.com.
How GPS navigation devices work
A traditional GPS device only calculates the co-ordinates in terms of latitude and longitude. Since differential GPS allows for pinpoint accuracy, it is now possible to display the exact location of a person on a map by juxtaposing the co-ordinates with known co-ordinates. GPS navigation devices today offer features like choosing the best route to a destination, detailed route maps, calculating the distance already travelled and also the popular 'bead crumb trail' that shows the exact path traversed. Contrary to popular belief, GPS navigation systems only have a limited number of maps stored into them, and additional maps have to be fed into the device's memory. If the GPS navigation system does not have a map it cannot offer more than just the GPS co-ordinates.
