Report on Beidou position (short message communication)

Beidou second-generation satellite navigation system consists of three parts: space satellite system, ground transportation control system and user application system.

Among them, the ground transportation control system is composed of main control station, injection station, monitoring station and other ground stations. The monitoring stations distributed within the national territory are responsible for monitoring the satellites within their visual range, collecting all kinds of observation data and sending them to the main control station, which will complete the accurate determination of navigation parameters such as satellite orbit, the processing of wide-area differential information and integrity information, and form uplink navigation messages and parameters.

In other words, the communication process is terminal-ground transportation control system-satellite-ground transportation control system-terminal.

I hope you can be satisfied!
