Abstract

Subsatellite point for geostationary satellite(GEO) need to be retained based on the continual orbit maneuver, especially for GEO satellite of partial subsatellite point. How to recover orbit rapidly for GEO based on short-arc tracking is the key factor to improve the service performance and usability of the navigation system. Due to its geostationary feather, GEO orbit parameters are strongly correlated with the clock corrections parameters in precise orbit determination (POD) using L-band pseudorange data, which needs supports by the time synchronization technique. This paper bringed forward a orbit rapid recovery method based on satellite clock offset and station clock offset. The satellite-ground time synchronization were realized by satellite-earth wireless two-way method, ground-ground time synchronization were realized by constellation combining orbit determination method. The precise orbit determination was realized using pseudorange and phase data without clock offset. A new method of parameters decorrelation based on prior restriction and a short-arc orbit determination method based on restriction by long-arc orbit determination were brought forward. The experiment based on ground data of Beidou system(BDS) indicated that the time of orbit recovery after maneuver was shortened from 24h to 4h. The 2-hour orbital prediction in radial component were better than 1m, which was evaluated SLR data. User equivalent range error (UERE) was better than 1.5m, and the precision was stable. The orbit recovery of of GEO of partial subsatellite point was come ture
