Is car navigation and GPS the same thing?

Car navigation and GPS are the same thing.

Global positioning system is written in English of GPS, which translates into global navigation system. In the vehicle-mounted GPS navigation system, the built-in GPS antenna will receive the data information transmitted by at least three of the 24 GPS satellites around the earth, and combine with the electronic map stored in the vehicle-mounted navigator to match the position coordinates determined by GPS satellite signals, so as to determine the accurate position of the vehicle in the electronic map, which is the usual positioning function.

Extended data:

GPS is a radio navigation and positioning system based on 24 global positioning satellites, which provides three-dimensional position, three-dimensional speed and other information to all parts of the world around the clock. The positioning principle of GPS is that the user receives the signal transmitted by the satellite, obtains the distance between the satellite and the user, clock correction, atmospheric correction and other parameters, and determines the user's position through data processing.

Automobile GPS navigation system consists of two parts: one part is composed of GPS receiver and display equipment installed on automobile workers; The other part is composed of computer control center, and the two parts are connected by positioning satellites. The computer control center is authorized by the motor vehicle management department and is responsible for observing the dynamics and traffic conditions of designated vehicles in the area at any time, so the whole car navigation system has at least two functions:

One is the track monitoring function. As long as the coded GPS receiver is installed in the car, the car can indicate its position on the electronic map of the computer control center no matter where it goes.

The other is the driver's 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 Turner's receiving device, the location of the car area and the current traffic situation will be immediately displayed on the display screen. You can not only enter the destination you want to go to, but also work out the best driving route in advance. You can accept the instructions from the computer control center to choose the route and direction of the car.

Car GPS also has great anti-theft function, which can be divided into static anti-theft and dynamic tracking. The former means that when the owner leaves the car and the parked vehicle is stolen, destroyed or moved, the vehicle sends an alarm to the GPS monitoring center through its own monitoring system and automatically contacts the owner's mobile phone to call the police. The latter can locate and track the stolen vehicles in operation, monitor the vehicle condition, record the vehicle trajectory, and even control the vehicle to cut off power and fuel.
