What makes GPS the vehicle tracking system of choice among civilians? Predictably enough, it’s its efficiency.

The answer to that is quite simple: GPS is currently the world’s only Global National Satellite System (or simply GNSS) that is fully operational. No other satellite system has the advanced technology that GPS utilizes, and yet since the GPS satellite system is being maintained and regulated by the government, its navigational services are completely cost-effective for the average civilian. This makes the GPS a very attractive protocol for vehicle tracking.

Most of the vehicle tracking systems today utilize either radio frequencies or GPRS as their communication protocol between the transmitter and the receiver. For example, LoJack and the LORAN vehicle tracking systems make use of radio frequencies to keep tracking of vehicles on the road. The GPS, on the other hand, utilizes microwave signals as satellite frequencies transmitted by at least 24 medium Earth orbit satellites to precisely track down a vehicle’s direction, speed, and location based on its transmitter. The sophisticated technology involved is completely free of charge, explaining the popularity of GPS above other national systems used at the civilian level.

Unlike some vehicle satellite-based navigational systems, GPS does not require line of sight for tracking to be effective. Even if your vehicle goes under a tunnel, it can still be tracked by the GPS tracking system.

Due to its versatility and technology, GPS can also be used for tracking other things aside from vehicles, such as navigational gears used in hiking or other outdoor activities. Environmental applications like checking atmospheric conditions and the gravity levels across the planet’s surface also benefit from GPS.
