利用 RTK 和全站仪进行河道横断面测量的应用和误差分析

对河道测量的一项重要的工作内容就是对河道横断面的测量，目前实时动态定位技术（ RTK ）已广泛应用于河道横断面的测量，与传统测量方法相比，其简单、快速以及准确性大大提高了河道横断面测量工作的效率，但在一些卫星信号不是很好的地方，如成片的树林、楼房， RTK的使用将会受到限制。本文主要结合全站仪对在此类地区的横断面测量进行分析。

Application s and Error Analysis of River Cross-Section Measurements Using RTK and Total Station

The cross-section measurement is an important content of the work for the river measurement .Real -time Kinematic （ RTK） positioning technology has been widely used in the river cross -section measurements compared with the traditional methods of measurement for its being simple , fast, and accuracy , which greatly improves the efficiency of the work of the river cross -section measurement.However, when the satellite signal is not good in some places , such as into a piece of woods , buildings, RTK will be limited.This paper analyzes cross -section measurements by total station in such areas .
