基于CORS的渠道断面测量方法

由于GPS连续运行参考站系统(CORS)可在一定区域内向大量用户同时提供精确可靠的实时差分定位信息,其在工程测量中的应用日益广泛。介绍了渠道纵横断面测量中的CORS测量方法、常规RTK测量方法和全站仪测量方法,并对其优缺点进行了比较;结合一个基于CORS的渠道纵横断面测量实例,进行了测量数据的处理与分析,对类似的测量工作有一定的参考价值。

Measurement Method of Channel Section Based on CORS

As GPS Continuously Operational Reference System can simultaneously provide accurate and reliable real-time differential positioning information for a large number of users in a certain region,it has been used more and more widely in engineering surveying.This paper firstly introduced CORS measurement method,traditional RTK measuring method and Total Station measuring method of channel section,and compared the advantages and disadvantages of them.Then,the data processing and analysis of an example of channel section measurement was producted,which provided some useful reference to similar surveying engineering.
