How GPS Vehicle Tracking Works?
GPS is the easiest way to track someone whether it is via cell phone, laptop or car. But, there are some misconceptions regarding it which we aim to set straight.
What is GPS?
Although majority of the populations uses GPS, hardly 60% of them would be able to even say its full form and that’s where the myth associated to GPS stems. GPS stands for Global Positioning System. The programme has 24 satellites till date which receive and record information while also allowing other technologies to use them. That’s how the tracking system works. It was implemented and is still maintained partially by U.S. Department of Defence despite being used globally. These satellites revolve around the Earth recording and sending signals from the GPS devices in the technology we use such as cell phones and cars.
How does it work?
A GPS system after it is being planted inside a device has to remain active in order to work. The use of Global Navigation Satellite system enables a GPS tracking system to use the microwave signals in order to provide accurate information about the location. No matter wherever the car is, the GPS tracking systems keeps sending microwave signals to the satellites orbiting the Earth which in turn records and sends the signals to the tracking devices to provide the information. While, the present information is generally expected of the tracking system, the history of navigation can also be traced via GPS system.
With the advancing technology, there are new developments every day. Nowadays, you can not only track the location of the vehicle, but you can also know about the speed and time covered or left of the journey the vehicle is on. So, that’s how your cab services tell you about the time left to reach the destination or how you compute your distance to home from workplace. Interesting, no?
The GPS system operates on a simple mathematical idea of trilateration. In addition to the simple know how of GPS tracking, one can also trace a 3 dimensional information of the whereabouts of a car with GPS system. This is done with the help of 4 GPS satellite signals. Now, the tracking devices do not get access directly from the satellites, instead there are Positioning System tracking stations which are situated across the globe. These tracking stations receive the signals directly from the satellites and then send these microwave signals to the GPS receivers which in order covert these microwave signals so that the estimated location can be determined.
The future holds more surprises as further development on the GPS system is in process. You can now track any of your vehicles, whether it is for professional reason or private. The risk of losing a car is also lessened with the GPS system. Technology has certainly made life easier!
