Precision Orbit Determination and Broadcast Ephemeris Orbit Analysis of Beidou Satellite Based on B1C/B2a Observation Data
Abstract This study focuses on the long-time performance of determined and broadcast ephemeris orbit of BDS-3 satellites using the iGMAS and MGEX B1C/B2a data in the two years since the opening of the global service. The results show that the radial accuracy of Beidou-3 MEO satellite precision orbit based on the new B1C/B2a observation is about 3 cm, and the IGSO satellites is around 8 cm. Except for GEOs, the average RMS of the broadcast ephemeris orbit of Beidou-3 IGSO/MEO satellites in radial, normal and tangential directions is about 0.10 m, 0.37 m and 0.36 m, which are better than GPS satellites. The user ranging error(SISRE) caused by the satellite orbit is approximately 14 cm. However, the satellite laser ranging(SLR) residuals of the broadcast ephemeris shows that there is an obvious systematic bias in the radial direction of broadcast orbit, which might reach nearly 10 cm.
