The principle of Beidou satellite navigation system is that after the reference station receives the satellite navigation signal, it forms the corresponding information through the data processing system, and then sends the information to the application terminal in real time through satellite, broadcast, mobile communication and other ways to realize the positioning service. The positioning accuracy of Beidou satellite navigation and positioning system is10m, the speed measuring accuracy is 0.2m per second, and the timing accuracy is10ns.

Beidou navigation system is a satellite navigation and positioning system independently built by China, which belongs to the Global Satellite Navigation System (NGSS) together with GPS of the United States, Galileo of Europe and GLONASS of Russia.

Composition of Beidou navigation system.

Beidou satellite navigation and positioning system consists of three parts: space segment, ground segment and user segment. According to Lanzhou Evening News, the space segment consists of three kinds of satellites: geostationary orbit, inclined geosynchronous orbit and medium earth orbit. The ground part includes several ground stations, such as reference station, main control station, time synchronization/injection station and monitoring station.

The user part includes basic products such as chips, modules and antennas compatible with other satellite navigation systems, as well as terminal products, application systems and application services. Beidou satellite navigation and positioning system will realize accurate positioning through these three parts.
