摘要	The original method of determination of satellite orbit by transfer, which was invented by NTSC (National Time Service Center, Chinese Academy of Sciences), and has been applying to project of Chinese Area Positioning System (CAPS) for satellite orbit determination successfully. The accuracy for range is about centimeter and the precise of orbit determination of is up to meter level. However, since the rich observation (each station implements continuous sampling in each second), it takes too long time to compute the satellite orbit, which has been affecting the work of the navigation system in real time. In order to enhance the calculating speed for satellite orbit determination, the observation data for determination of satellite orbit should be reduced without distortion. In this paper, we proposed a method by generating normal points to reduce observation data. The results of computation show that our method not only reduces the time of computing satellite orbit greatly, and also the orbit using the normal point is nearly same as the orbit with all of the observation data. The difference of two orbits is in a few millimeters
