Satellite vehicle monitoring is a system of satellite monitoring and control of moving objects, based on the use of modern satellite navigation systems (GLONASS and GPS), communication equipment and technology (GSM WiFi), computer technology and digital maps.
The vehicle is equipped with an onboard controller (tracker), which includes a multichannel GLONASS/GPS navigation receiver and a GSM-modem with antennas. The navigation receiver receives signals emitted by GLONASS and GPS satellites and calculates its own coordinates. Calculated coordinates via GSM-cellular network are transmitted to the system server, where they are processed and transmitted to the dispatcher program for building reports and display location on the map. In addition to coordinates, the onboard controller can also transmit additional information about the state of connected sensors and modes of operation.
