A BeiDou/GPS indirect fusion process method based on double-difference data was proposed in this article. Based on the multi-mode navigation data from the 6 internal stations and 10 foreign stations of M-GEX (The IGS Multi-GNSS Global Experiment) combined with the GPS data from 120 IGS (International GPS Service) stations, an accuracy verification test of orbit determination was developed. The results show that the accuracy of satellite orbit overlap is about 10 cm in radial direction for BeiDou IGSO. For MEO the accuracy is 15 cm in radial direction and for GEO is about 20 cm. The orbit RMS for GPS satellite is about 2 cm by comparing with IGS final products.
