摘　　要：基于CORS系统的GPS网络RTK技术克服了普通RTK测量中基准站与流动站间距的局限,它的有效距离可以达到几十甚至上百千米,覆盖面广阔,定位精度高,可靠性强。这是GPS网络RTK技术能够快速发展的原因之一。本文以淮南某用地勘测定界项目为例,研究探讨了GPS网络RTK用于土地勘测定界及精度分析的方法,得到了一些有益的结论。The GPS-network RTK technology which is based on CORS system has overcome the restraint of the distance that exists between datum station and moving station of ordinary RTK measurement.Its effective distance can reach dozens or even hundreds of kilometers.Not only does it cover a wider area, but also it has high positioning accuracy.What is more, it has a strong reliability. This is also one of the reasons that the GPS-network RTK can be developed rapidly.In this paper the author make a study through ci-ting a case of land survey delimitation project.The study discusses the GPS-network RTK for land survey delimitation and the accu-racy analysis method, and some useful conclusions are obtained.
