Have you heard about some of the new technology that makes GPS tracking for cars accessible to normal people like you and me? GPS technology is becoming increasingly available to consumers at every level of life, and because of this we are constantly finding new and interesting ways to apply this technology. The ability to track a car, whether it is for safety reasons or to catch a cheating spouse, is now well within the means of anyone with access to the car and a hundred or so dollars.
The Basics of GPS Tracking
Right now, as you sit and read this article, there are at least 24 satellites orbiting the earth 11 nautical miles above its surface. These same satellites transmit a signal that specialized receivers are able to pick up. Within each signal that the the satellite is broadcasting is some important information that a GPS receiver is going to use to generate position information in the form of a longitude and latitude. This information is the position of the satellite and the time the signal was sent.
A GPS device then takes this information and calculates the space separating the receiver from the satellite. The device will begin by taking the speed of the signal and multiplying it by the amount of time it took the signal to reach the GPS receiver. The equation for this looks something like this:
Speed x Time = Distance Traveled
This will tell you just how far away you are from one satellite. This just tells you how far away you are from the single satellite. The information from this single satellite is not enough. Three satellites is the magic number of signals that you need to receive in order to get a proper fix on your location. This process is known as trilateration and it is very much like triangulation, except that trilateration works in three dimensions while triangulation works in just two.
Once the tracker has established your position it logs that data in a database and keeps the data all to itself or communicates it to some other party. If the GPS tracking device for cars keeps the information it is called a data logger. Because the device simply stores the data within itself, such a device is not able to be used in real time GPS tracking. For real time updates you need a data pusher. This device will transmit the information that it processed from the satellites to a central location. Here the data will become available to anyone with access to it – whether it is a parent tracking the car of their teen or a city employee monitoring worker productivity.
The number of reasons why you might consider using GPS tracking for cars are many. You don’t need to have lots of technical skills to make these tracking devices work. All that is required is a some cash! The service provider that you go with will be able to provide the rest. Getting a handle on the company you are going to use is crucial, check them out at the Better Business Bureau or talk to customers of the service. In the final analysis, if this type of location monitoring is for you then consider using GPS tracking for car.
