摘要：

为了验证与分析全球定位系统（GPS）与北斗卫星导航系统联合定位相较于GPS单系统定位在亚太地区的优势，利用GPS/北斗双频双模接收机开展不同模式下的动/静态单点定位实验和实时动态差分法（RTK）实验，并通过对实测数据的分析，给出了北斗导航卫星对GPS单系统定位的影响.结果表明，GPS/北斗双系统卫星观测相对于GPS单系统在卫星可视数量、卫星对于测站的几何分布、扩大连续运行参考站系统（CORS）网的作用范围等方面有很大的优势，而且双系统组合定位算法有效地提高了接收机的定位性能.

Abstract:

The GPS/Beidou integrated system has more advantages over GPS because it uses the GPS/ Beidou integrated mode receiver for satellite signal quality test. Based on a comprehensive analysis of the experimental data, a qualitative conclusion can be drawn that the Beidou navigation system has some positive effects on positioning with GPS only. Compared with GPS, satellite observation with the GPS/Beidou integrated system has more advantages over GPS on the quantity of visible satellite, the geometric distribution of satellite to observation station and expansion of the CORS network coverage. Moreover, it can improve the positioning capability of receivers.

Key words: Beidou, dilution of precision （DOP）, global positioning system (GPS), satellite visibility
