What does Beidou positioning mean?

Beidou positioning is Beidou satellite navigation system.

China Beidou satellite navigation system is a global satellite navigation system developed by China, and it is the third mature satellite navigation system after GPS and GLONASS. Beidou satellite navigation system, American GPS, Russian GLONASS and EU Galileo are the suppliers recognized by the United Nations Satellite Navigation Committee.

Beidou satellite navigation system consists of three parts: space segment, ground segment and user segment. It can provide high-precision and high-reliability positioning, navigation and time service for all kinds of users around the world all day, and has the ability of short message communication.

Enhanced Beidou positioning system;

Beidou satellite navigation system is an important part of Beidou augmentation system. The geostationary satellite is equipped with satellite navigation enhanced signal transponder, which can broadcast ephemeris error, satellite clock error, ionospheric delay and other correction information to users, thus improving the positioning accuracy of the original satellite navigation system.

According to the international civil aviation standards, the Beidou augmentation system will be designed, tested and built. The demonstration of the system implementation scheme has been completed, which consolidates the technical position of the system in the next generation dual-frequency multi-constellation SBAS standard and further consolidates the position of BDSBAS as a satellite-based enhanced service provider.
