Paper Abstract

Some Orbit Determination (OD) of Low Earth Orbiters (LEOs) based on undifferenced spaceborne GPS data were discussed firstly in this paper. Then the principle and mathematical models of two different types of reduced-dynamic were present. After that, dual-frequency spaceborne GPS data of doy 89, 2004 from CHAMP and GRACE satellite were computed using two types of reduced-dynamic POD and the OD results were analyzed. Our CHAMP orbiting results of one day using two different reduced dynamic POD methods are within 7 centimeters compared with GFZ Post processed Science Orbits (PSO) and the GRACE orbiting results are with 3 centimeters compared with JPL OD results.
