Paper Abstract

Some orbit determination methods using onboard GPS Observations were discussed firstly in this paper, especially the principle and mathematical model of reduced-dynamic Precise Orbit Determination (POD) of Low Earth Satellite (LEO) based on undifferenced spaceborne dual-frequency GPS data. Then a weeklong (from July 28, 2003 to August 3,2003) dual-frequency onboard GPS observation from CHAMP satellite was computed using reduced-dynamic POD. Compared with TUM solutions, our CHAMP orbiting results of one week using reduced dynamic POD method are within 8 centimeters, which can meet the requirements of some higher precision orbit satellite orbits. In order to obtain high precision orbiting results, the impact of different gravity models and proper interval of pseudo-stochastic-pulses on the orbit determination accuracy were analyzed as well.
