????The on-board system receives the data about the coordinate position of the satellite itself sent by satellites (24 in total, running in 6 satellite orbits on average) every second. The user receiver can calculate its own position data based on the data sent by the three satellites. For mobile vehicles, the data of the fourth satellite is required to calculate the moving speed and direction of the mobile vehicle. The coordinate data is transmitted through the modem. Through the communication network, the control center restores the coordinate data and other information sent back by the on-board system through the modem, matches it with the electronic map on the workstation, and displays the current correct position of the tracked vehicle on the map, so the monitoring center can clearly grasp the macro dynamic position information and operation status of the vehicle.
