摘　　要：多卫星导航系统间实现互用是提高导航定位性能的重要途径,目前已成为全球卫星导航领域关注的热点和发展方向。我国正在建设新一代卫星导航系统,为保护国家利益,获得世界认同与支持,COMPASS必须走与其他导航系统的兼容之路。本文分析了我国新一代卫星导航系统与GPS系统兼容定位算法和性能,并利用实测数据计算得到了COMPASS-M1与GPS兼容定位结果,验证了COMPASS与GPS兼容定位的可能性。The interoperability of multi-satellite navlgahon systems 1s all Important way to improve me perIormance oi nawgauon, and it has become the trend of GNSS development. China is building a new generation of satellite navigation systems, for the protection of national interests and the world＇ s recognition and support, COMPASS must be compatible with the others. This paper analyzed the algorithm and performance of compatible positioning with COMPASS and GPS, and calculated the compatible results using the observa- tion data. Tile possibility of the compatible positioning with COMPASS and GPS was verified finally.
