| Abstract: | Firstly,the paper introduces three different gravity field models for LEO satellites and the dynamical models in reduced-dynamic or dynamic orbit determination,then it is possible to compare the orbit integration results to JPL rapid precise orbit.All the results indicate that the EIGEN-2 model coefficients which was produced by CHAMP SST data has higher precision and that model can meet the needs of precise orbit determination of LEO satellites. |
| Keywords: | gravity field models LEO satellites orbit integration EIGEN-2 |
