基于连续运行GPS基准站系统的城市三维大地测量基准建设方案探讨

Discussing of the construction project of 3D standard of geodetic survey in city which is based on uninterrupted working GPS base station system

本文分析了福州三维大地测量基准现状与存在的问题,介绍了GPS网络RTK的定位原理,提出了基于连续运行GPS基准站系统的城市三维大地测量基准建设方案以及基于移去-计算-恢复(RCR)算法来求得其他待求GPS点的高程异常技术和方法。

In this article, we analyzes the status quo and the problems of 3D standard of geodetic survey in Fuzhou, and discusses the technologies and the methods about the 3D standard of geodetic survey construction project in city, which is based on the continuous base station of GPS, and the algorithm which is based on RCR, and then find the height anomaly of other unknown GPS points, and it also introduced the locating principles of GPS RTK networks.
