| 摘 要： | 基于非差观测的网络实时动态定位(RTK)方法通过提供每颗卫星的误差改正量,使网内用户获得与网络RTK方法等价的快速精密单点定位服务。当用户跨越连续运行基准站(CORS)网内由不同参考站组成的子网(参考子网)甚至跨越不同CORS网时,都能有效避免因所选取的主参考站变化而引起的模糊度重新初始化,从而保持观测时段内用户定位结果的连续可靠和跨CORS网服务时算法上的无缝衔接。通过对海上实测动态数据处理结果的分析,验证该方法的定位精度、初始化时间与现有网络RTK方法在量级上的一致性,以及跨不同参考子网和CORS网时实现无缝衔接的有效性。

| Abstract: | Method of Network RTK based on undifferenced observation corrections allows clients to gain rapid and precise positioning service in undifferenced processing mode equivalent to Network RTK by providing error corrections of each satellite.Compared with current Network RTK,the new method could efficiently solve problems of ambiguity re-initialization caused by selected main reference stations change under circumstances of cross reference sub-networks within the same CORS network,or even cross different CORS n... |
