| Abstract: | GEO satellites are widely used in communication,meteorology,navigation and location,earth observation,data relay and other fields.And the requirement of orbit determination precision is also higher and higher.Combining with the high-precision measurement system of satellite system at home and abroad,this paper introduces two development trends of high-precision orbit determination technology for GEO satellites in China:centimeter-level high-precision multi-station ranging technology and CEI measurement and orbit determination technology.The error analysis,key technologies and solutions of the two technologies above are provided,and the recent experimental progress is introduced.The result of the experiment shows that,the two technologies given above can achieve real-time orbit determination accuracy close to 10 meters,which can satisfy the requirements of high-precision orbit determination of GEO satellite in China. |
