摘　　要：GLONASS与GPS导航定位技术原理相似 ,GPS/GLONASS组合测量由于可见卫星数目的增加 ,可以提高测量的精度、可靠性、完备性。At the beginning of 1996, another satellite navigation system, GLONASS, which was owned and developed by Russia, was put into service. Similar with GPS, GLONASS have two carriers too. But the frequencies of the different satellites are not the same. GPS/GLONASS integrated measurement will be used widely in the future. In this paper, the error sources and its properties are introduced and analyzed.
