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.
The GPS/Beidou integrated system has more dou integrated mode receiver for satellite signal quality advantages over GPS because it uses the GPS/Bei test. Based on a comprehensive analysis of the ex perimental 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 in- tegrated system has more advantages over GPS on the quantity of visible satellite, the geometric distribu- tion of satellite to observation station and expansion of the CORS network coverage. Moreover, it can im- prove the positioning capability of receivers.
