On-Orbit Operation State Analysis of Beidou Satellite Based on the Broadcast Ephemeris
Abstract As the satellite’s running state is described by broadcast ephemeris, it thus ensures the user’s real-time navigation and positioning service. In this paper, the orbital and clock parameters extracted from the broadcast ephemeris, which include satellite orbit plane, shape, orientation parameters and satellite clock sequence, are used to analyze Beidou on-orbit satellite’s operation state at the present stage. The multi-results show that anomalies often occur in satellite orbit clock; in addition, the highest frequency anomalies occur in BDS GEO satellite, while the IGSO satellite keeps the middle level, and the MEO satellite maintains the most stable operation.
Key words ：
operation state of Beidou satellite
satellite orbital parameters
satellite clock error
