For a LEO satellite with an onboard GNSS receiver, the TT&C equipment on the ground can receive dual-frequency GNSS observation data with an arc length of about 12 h of the satellite within about 10 min of the visible arc. At the same time, the international GNSS Monitoring and Assessment System (iGMAS) of China can provide Ultra-rapid orbit and clock offset products of the BDS, GPS, GLONASS and Galileo satellites, and high-precision Earth Orientation Parameters (EOP) in this data arc. Therefore, using these Ultra-rapid products and the dual-frequency GNSS data, we can achieve the precise orbit determination and complete the orbit prediction. Based on this technology, it is possible to reduce the number of laps of satellite tracking by ground equipment, and to achieve precision orbit determination; at the same time, the orbit determination software can realize automatic and autonomous operation.
