Abstract: Spaceborne global navigation satellite system (GNSS) method is used to overcome the problem of poor satellite visibility  when using GPS for orbit determination of geostationary orbit (GEO) satellite. For FENGYUN geostationary satellite, the visibility of GEO satellite relative to GNSS in the future was analyzed. Since the sampling interval of navigation receiver is a little  longer, an integral filter method, combined with the orbit integral and Kalman filter methods, was proposed to determine the geostationary satellite orbit. After generating the necessary data by STK software and programming by MATLAB software, a simulation test was made. The simulation results  show that the performance of the proposed method is good and that accuracy of orbit  determination  for GEO satellite is higher.
