THE ORBIT DETERMINATION TECHNIQUE OF GEOSTATIONARY SATELLITE USING STAR SENSING FUNCTION OF THE METEOROLOGICAL IMAGER

A conceptual study about the angle information based orbit determination technique for a geostationary satellite was performed. With an assumption that the simultaneous observing of the earth and nearby stars is possible, we confirmed that the view angles between the earth and stars can be use as inputs for orbit determination process. By the MA TLAB simulation with least square method, the convergence is confirmed. This conceptual study was performed with the COMS for instance. This technique will be able to use as a back-up of ground station's orbit determination or a part of autonomous satellite operation.
