Abstract
Autonomous orbit determination and time synchronization based on inter-satellite-link is core of autonomous navigation for navigation constellation. On the basis of the on-orbit Data of inter-satellite links system of test satellites of BD global navigation satellite system, autonomous orbit determination test had been carried out using space-borne autonomous navigation prototype software in this paper. The test work consisted of analysis for inter-satellite ranging and satellite-ground ranging, precision analysis of autonomous orbit prediction which grounded long-term forecast reference ephemeris, and analysis for autonomous orbit determination which based on on-orbit data of inter-satellite system. The precise orbit determined by both inter-satellite and satellite-ground ranging had been used as standard, which offered by master control station of operational control system. The result proved that, SIS-URE of autonomous orbit determination of four test satellites are all better than 5 m (1σ).
