网络RTK技术提高了测量精度与测量效率,全国各地大力开展CORS系统建设。 CORS系统采用WGS84基准,其与工程应用基准常常不一致,这将降低CORS应用的效率。为直接实时获取地方坐标,一般需要在流动站设置相关坐标系参数,但这违背国家保密法。为此笔者研究CORS系统的运行机制与工作原理,探索一种基于重庆市GPS综合服务系统VRS技术实时获取地方坐标方法并通过了试验验证。
網絡RTK技術提高瞭測量精度與測量效率,全國各地大力開展CORS繫統建設。 CORS繫統採用WGS84基準,其與工程應用基準常常不一緻,這將降低CORS應用的效率。為直接實時穫取地方坐標,一般需要在流動站設置相關坐標繫參數,但這違揹國傢保密法。為此筆者研究CORS繫統的運行機製與工作原理,探索一種基于重慶市GPS綜閤服務繫統VRS技術實時穫取地方坐標方法併通過瞭試驗驗證。

The Technology of Network RTK has improved the Precision and Efficiency of Engineering survey.All o-ver the country are carrying out the construction of CORS system.The datum of Continuous Operation Reference Station, which is the WGS84,is different from one of the engineering application.So it reduces the efficiency.TO get the local coordinates in using CORS,we must set the relevant coordinate parameters in rover station.This is contrary to the state security law.SO I have researched theoperation mechanism and working principle of CORS and have explored themethod how to get real time local coordinate in CQGISS using the Technology of the Virtual Reference Station.It has been veri-fied by experiments.
