摘　　要：随着全球各导航卫星系统的兴建,多种导航卫星系统的组合共用在近年来逐步成为卫星导航领域的研究热点。从导航系统的星座及观测几何、可用性、完备性、精度、可靠性、载波相位模糊度求解能力等方面,分析了多种导航卫星系统组合共用的优越性。阐述了组合共用的使能技术及最新的研究进展,并对发展前景做出了展望。With the construction of multiple global navigation satellite systems, the GNSS integration is gradually becoming a focus in the field of satellite navigation in recent years. The advantages of the integrated GNSS were analyzed from several aspects, including the constellation design, observing geometry, availability, integrity, precision, reliability and the capability of carrier phase ambiguity resolution. The enabling technologies and the latest research progresses of the integrated utilization were illustrated, and the development prospects were also proposed.
