GPS-RTK高差测量代替四等水准可行性的探讨

摘要

This paper introduced the basic principle of GPS-RTK height difference measurement,using the RTK observed the single point elevation,gained the height difference of adjacent points,and then using DS3 water level observed these elevation points,compared with the two group of elevation data,and then draw the conclusion that GPS-RTK height difference measurement could replace fourth order leveling measurement.%介绍了GPS-RTK高程测量的基本原理,利用RTK观测单点高程,求出相邻点的高差,再使用DS3水准仪进行观测这些高程点,得到两组高差数据进行比较,进而得出GPS-RTK高差测量能够代替四等水准高差测量的结论。
