Extended information:

The vehicle navigation system is mainly composed of a navigation host and a navigation display terminal. The built-in GPS antenna will receive data information from at least three of the 24 GPS satellites orbiting the earth, thus determining the current position of the car. By matching the position coordinates determined by the navigation host through the GPS satellite signal with the electronic map data, the accurate position of the car in the electronic map can be determined.

on this basis, it will realize many functions, such as driving navigation, route recommendation, information inquiry, playing AV/TV and so on. The driver can realize the above functions only by watching the picture on the display, listening to the voice prompt and manipulating the remote controller in his hand, so as to drive easily and freely.

The automobile GPS navigation system consists of two parts:

One part consists of a GPS receiver and a display device installed on the automobile; The other part is composed of computer control center, and the two parts are connected by positioning satellites.

the computer control center is authorized and set up by the motor vehicle management department, and it is responsible for observing the dynamics and traffic conditions of the vehicles designated for monitoring in the jurisdiction at any time. Therefore, the whole car navigation system has at least two functions: one is the car trail monitoring function. As long as the coded GPS receiver is installed on the car, the car can indicate its location through the electronic map of the computer control center no matter where it travels.

the other is the driver's guide function, in which the owner can store the electronic map of traffic routes in various areas on the floppy disk. As long as the floppy disk is inserted into the vehicle receiving device, the location and current traffic status of the vehicle will be immediately displayed on the display screen, which can not only input the destination to be visited, but also compile the best driving route in advance, and also accept the instructions of the computer control center to select the driving route and direction of the vehicle.
