【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。
[Abstract]:The orbit parameters and clock difference parameters of Beidou satellite are extracted from the broadcast ephemeris data of Beidou satellite. The operating state of Beidou in orbit satellite is analyzed from the aspects of satellite orbit plane parameters, shape parameters, orientation parameters and satellite clock difference sequence. The results show that the orbit anomaly of BDS satellite is more than that of satellite clock difference anomaly, among which the frequency of abnormal GEO satellite is the highest, that of IGSO satellite is the second, and that of MEO satellite is the most stable.
