摘　　要：利用北斗卫星的广播星历数据提取轨道参数与钟差参数指标,从卫星轨道平面参数、形状参数、定向参数和卫星钟差序列等方面对现阶段北斗在轨卫星的运行状态进行分析。结果表明,BDS卫星的轨道异常多于卫星钟差异常,其中GEO卫星出现异常的频率最高,IGSO卫星次之,MEO卫星的运行状态最稳定。As the satellite＇s running state is described by broadcast ephemeris, it thus ensures the user＇s realtime 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.
