The car navigation system is mainly composed of a navigation host and a navigation display terminal. The built-in GPS antenna will receive data from at least 3 of the 24 GPS satellites surrounding the earth, thereby determining the current position of the car. The position coordinates determined by the navigation host through the GPS satellite signals match the electronic map data, and the exact position of the car in the electronic map can be determined.
On this basis, various functions such as car navigation, route recommendation, information query, and AV / TV playback will be realized. The driver only needs to watch the screen on the display, listen to the voice prompts, and manipulate the remote control in his hand to achieve the above functions, thereby driving easily and freely.
The car GPS navigation system consists of two parts:
One part consists of a GPS receiver and display device installed on the car; the other part consists of a computer control center, and the two parts communicate with each other through positioning satellites.
The computer control center is authorized and established by the motor vehicle management department. It is responsible for observing the dynamics and traffic conditions of the designated monitoring vehicles in the jurisdiction at any time. Therefore, the entire car navigation system has at least two functions:
One is the car track monitoring function. As long as the encoded GPS receiving device is installed on the car, the car can indicate its location through the electronic map of the computer control center no matter where it is traveling;
The other is the driving guide function. The owner can store the electronic maps of the transportation lines in various areas on the floppy disk. As long as the floppy disk is inserted into the receiving device on the car, the display will immediately show the location of the car and the current traffic on the display. State, you can either enter the destination you want to go to, prepare the best driving route in advance, or accept the instructions of the computer control center to choose the route and direction of the car.
