| Abstract: | In this paper,we firstly determined the CHAMP satellite orbit based on GPS data from March 3,2008 to March 10,2008 using undifferenced reduced-dynamic method.Then,in order to evaluate the orbit accuracy of this method,we take the rapid orbit of GFZ as the reference standard.The results show that,the accuracy of the orbits obtained is 7 cm in 1D position and 0.1mm/s in 1D speed. |
