| Abstract: | Based on the basic theory of Precise Orbit Determination,the method of the reduced-dynamic orbit determination using zero-difference data onboard GPS observations was researched in this paper·The orbit of GRACE satellite was determined by the auto-nomic software CASMORD.Compared GRACE orbiting results of reduced-dynamic method’s solutions with JPL’s PSO and SLR measurement,the results showed that the 3D-RMS was better than 7 cm and the direction ofX,Y,Zwas about3～5 cm,to demonstrate the feasibility and practicability of this method. |
