| Abstract: | An autonomous orbit determination for satellites based on information of Sun-Earth-Moon is studied. At intervals of no eclipse, the method of determination of position vector of satellite using ephemeris of Sun and Moon onboard and measurements of Sun, Earth and Moon is given. Using observation vector of position, the real-time orbit determination for satellites by the extended Kalman filtering is studied. At intervals of eclipse, orbit is obtained using proper orbit dynamic modeling. The procedure of autonomous orbit determination is validated using digital simulation. |
