摘要
从GPS控制网联测国家高级平面和高程控制点所遇到的实际问题出发,讨论了觇标下、障碍物附近等困难条件下,GPS网观测时段的优化问题,提出了相关精度因子的概念,具有很实用的指导作用。
In this paper,from the problems encountered in combining GPS networks with control points in national plane and elevation control networks,the optimization problem of observation stage in GPS network in difficult conditions such as under tower and near barrier etc is discussed.Then the con-cept of the related precision factor is provided,which has a guidance to practice.
