| Abstract: | In order to estimate orbit position of GE0 satellites using existing on-board equipments, this paper describes the system composed of sun sensors and earth sensors. According to nature of orbit of GEO sat- ellites combined with Hill equation, state equations and measurement equations of this system are established by using measurement information from sun sensors and earth sensors, as well as orbit perturbation characteristics. Simulation results show that longitude＇ s excursion of the satellite can be accurately estimated by this method, and it is a feasible autonomous navigation method for GEO satellites |
