Automobile GPS navigation system consists of two parts: one part is composed of GPS receiver and display equipment installed in the automobile; The other part is composed of computer control center, and the two parts are connected by positioning satellites.
Authorized by the motor vehicle management department, the computer control center is responsible for observing the dynamics and traffic conditions of designated monitoring vehicles within its jurisdiction at any time. Therefore, the whole car navigation system has at least two functions: first, the car trajectory monitoring function, as long as the coded GPS receiver is installed on the car, the car can indicate its position through the electronic map of the computer control center wherever it goes; The other is the driving guidance function. Car owners can store electronic maps of traffic routes in various regions on floppy disks. As long as the floppy disk is inserted into the receiving device of the vehicle, the traffic situation of the vehicle in this area will be immediately displayed on the display screen. Not only can the destination be input, but also the best driving route can be compiled in advance, and the driving route and direction of the vehicle can be selected under the instruction of the computer control center.
