New Results of Multi-GNSS Orbits Validation Based on SLR Observationsodels such as station coordinates, laser propagation delay models were introduced to establish the measurement model. The validation of the BACC orbits shows a mean deviation around 5–10 cm for the GLONASS satellites, 10–15 cm for the COMPASS MEO/IGSO satellites, 2.65 m for the COMPASS GEO satellites, and 20–25 cm for the GALILEO satellites.

Research of KeyTechnology on the Combination of GPS, VLBI, SLR and DORIS Solution for Station Coordi fused with DORIS solutions, the combined solution of LOD generally keep a consistency with C04, the WRMS is 0.026 ms, but UT show a large difference and unconsistence with C04 and the optimal solution because it could only be determined by VLBI.

Radiological Reporting in the United States, satellite system. However, the result of precise orbit determination and orbit prediction affected the precision of broadcast ephemeris. It’s a very complex task to calculate the precise orbit of satellite. The in-orbit satellite is effected by several kinds of perturbations, that are Earth’s non-s

The constellation of BeiDou Navigation Satellite System (BDS) is different from that of GPS. GPS constellation includes only Medium Earth Orbit (MEO) satellites, while BDS constellation is composed of three types
