【摘要】:利用北斗衛(wèi)星的廣播星歷數(shù)據(jù)提取軌道參數(shù)與鐘差參數(shù)指標(biāo),從衛(wèi)星軌道平面參數(shù)、形狀參數(shù)、定向參數(shù)和衛(wèi)星鐘差序列等方面對現(xiàn)階段北斗在軌衛(wèi)星的運行狀態(tài)進(jìn)行分析。結(jié)果表明,BDS衛(wèi)星的軌道異常多于衛(wèi)星鐘差異常,其中GEO衛(wèi)星出現(xiàn)異常的頻率最高,IGSO衛(wèi)星次之,MEO衛(wèi)星的運行狀態(tài)最穩(wěn)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.
