兰州市 CORS 系统定位精度测试及应用

摘要

CORS系统的定位精度检测是系统整体性能测试中一项最重要的内容，也是系统用户最为关心的。简述了CORS系统定位误差源，分析比较了几种常用定位精度测试方法的优缺点，在利用兰州市CORS系统第一次作业时，对该系统的定位精度进行了测试和评价分析。测试结果表明，该系统定位精度可靠性高，可满足作业需求。%The positioning accuracy is one of the most important test contents of CORS and it is paid great attention by users .Based on briefly introducing the error source of CORS positioning ,this paper analyses and compares the advantages and disadvantages of several commonused detection methods for CORS ,Combining Lanzhou CORS to work for the first time ,the positioning accuracy of it is tested and evaluated .The experimentation results indi‐cate that positioning accuracy of the system is reliable ,meeting surveying job requirements .
