Abstract At present, the application of GPS in geoscience researchs mainly with the aid of the final ephemeris released by IGS, which is calculated from 140 global distribution stations and the accuracy is better than 5 cm. These stations mainly distribute in Europe and America, less than two are in China, so the orbit is not optimal for us. Along with that the China’s Crust Movement Observation Network (CMONOC) sets up and run, continuous tracking station can widely cover China in regional, and provide conditions for orbit determination. We use the global nets and regional nets for respectively orbit determination, then integrate them and studies the improvement of local orbit. This is of important significance for produce our satellite ephemeris by use of more regional stations.
