| Abstract: | The factors that influence the Earth pointing precision by using the star tracker are analyzed. The analytical expressions of pointing errors are given, which are affected by orbital parameters in the directions of both the longitude and latitude. Simulation results show that the analytical results are consistent with the computational results. |
