A GPS unit is mainly made up of three segments: the satellites, the control system, and the user.
There are over two-dozen satellites stationed just outside the earth’s atmosphere. These machines are about 11,000 nautical miles above the surface and they are funded and controlled by the US Department of Defense. In order to control these satellites, there are control or monitoring stations in several strategic locations across the globe. These are the units that get the information from the satellites, monitor, and analyze them for any significance in government operations. The user holds the receiver of the radio signals from the orbiting satellites. It can compute its distance from the satellite by using the time stamps on the radio waves that were sent. android gps tracker spy
To zoom in to a specific location, four satellites are needed. The accuracy is around 10-15 meters so it doesn’t really help if the object being tracked is a car that is about 3 meters long. This is why there have been upgrades like the Differential GPS, which helps give more accurate information on the precise location of a vehicle.
Application in cars, the GPS tracker technology has found a lot of use in so many things that need to be tracked. The primary application is in vehicles. With the GPS tracking device installed in the car, the owner is certain that he won’t get lost even in places unknown to him. The screen that is hooked on to the GPS system of his car will help him find his way onto the nearest main road leading to his destination – that is, if he got lost.
The best use for the GPS tracking system is in the unfortunate event that the car gets stolen. If you only have the ordinary alarm system installed, you can’t be sure about your car’s total safety. This is because any skilled car thief can easily override your alarm system and get away with your car – and you will never hear from it again.
The GPS tracker system is a genius of a tracker so your thief can’t really go far with your car. The minute you suspect that it’s been stolen, you can just report to the authorities immediately and they can tap into the GPS system so they can instantly check where your car is at that very instant.
