The Global Positioning System (GPS) is a satellite-based Tracking system that consists of 24 orbiting satellites, each of which makes two circuits around the Earth every 24 hours. These satellites transmit three bits of information – the satellite's number, its position in space, and the time the information is sent. These signals are picked up by the GPS receiver, which uses this information to calculate the distance between it and the GPS satellites.1-RealTime TrackingIn Real Time Tracking You Can get the following details of the vehicle.A- Vehicle NameB-Current Data TimeC- Vehicle Current SpeedD – Vehicle Engine Status ON/OFF2-Vehicle Control CommandThis feature allow you to stop / start your vehicle remotely.
