It is said that had it not been for a GPS tracking device in OJ Simpson's mobile phone, he would not have been found to be tried on his wife's murder. A GPS vehicle tracking device is much like driving around in your car with your mobile phone. It allows a person to locate the current position of a moving vehicle or identify where it's been and as well, where it is heading. This is ideal for chasing criminals who has just fled the scene of the crime or finding where a suspicious vehicle will be heading next.

A GPS tracking device calculates its position by measuring distances between itself and other GPS satellites. In return, the signals emitted by the satellites carry information about the GPS carrier's location. Aside from absolute location, other civilian benefits from having GPS vehicle tracking devices include relative movement. Relative movement is useful in ships and vessels to calculate certain time distance calculations including velocity made good toward your destination and crosstrac error calculations.

Additional benefits of using GPS vehicle tracking devices is the ability to know let the carrier know exactly where their vehicle is located and its direction of travel. This technology can also create a digital view of the vehicle's current position in a geographic map. This information can be valuable in remote locations that do not have established road names or where the vehicle may be traveling off road. More advanced GPS devices can even tell you which turn to take or which roads to take to reach a destination. Life is now easier drivers who simply get on their cars and start their engines without knowing where to go. GPS in vehicles has given everyone the ability to navigate to about any location on the earth. As a result the world is a much small place than it was just a few short years ago. Now we can find our present location, where have been or going to, with a simple click of a button.

So, if you ever wonder where your car may be, your GPS can track where it is to within a few meters. If by chance your car gets stolen, you can easily find where it is heading or where it currently is. Suppose a vehicle stops in the middle of nowhere because of some car trouble, the driver could easily ask for help, or his location could easily be tracked for emergency assistance, that is for as long as there is a signal. GPS tracking will not work without it. This feature has the potential to decrease car theft or even robberies with getaway vehicles. This can also give cheating husbands or spouses a second thought on their actions. Moving around in vehicles with GPS can very well ruin a secret affair because of its non-discreet ability to identify one's exact location.

Having this new and useful technology, GPS tracking devices in your mobile phones or GPS vehicle tracking devices in your vehicle, we are giving away a part of our lives to be known to others for a price. This loss of privacy is of great concern may many people. Basically we are giving away information about our lives for sake of more information. If you do purchase and install GPS vehicle tracking devices, then you should expect that somebody else can use the GPS tracking information you provide for their own benefit. Unless we a doing something illegal or immoral we really have little fear from the misuse of any GPS tracking information we generate each day.
