Explain how to write the beginning of Beidou satellite.

The explanatory text about "Beidou satellite" begins with a macro introduction to Beidou satellite, which can be written as follows:

1, basic information:

China Beidou satellite navigation system is a global satellite navigation system independently 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.

2. International cooperation:

Globally, 137 countries have signed cooperation agreements with Beidou satellite navigation system. With the success of global networking, the future international application space of Beidou satellite navigation system will continue to expand.

Basic components of Beidou satellite navigation system;

(1) Beidou system consists of three parts: space segment, ground segment and user segment.

(2) The space segment consists of several geostationary orbit satellites, inclined geosynchronous orbit satellites and medium-earth orbit satellites.

(3) The ground segment includes several ground stations such as master control station, time synchronization/injection station, monitoring station and inter-satellite link operation management facilities.

(4) The user section includes basic products such as Beidou, chips, modules and antennas compatible with other satellite navigation systems, as well as terminal equipment, application systems and application services.
