基于吉林 CORS 的线路工程测量技术研究

以基于CORS的线路工程测量为研究对象，以长春某石化供气管道工程为研究背景，简要介绍了吉林CORS系统的特点和功能，分析了吉林CORS在石化供气管道测量中的应用模式。在此基础上，探讨了作业实施方法及测量结果，并进行了误差分析。通过对比采用吉林CORS系统和常规RTK测量方式两种方法得出的数据精度，总结出吉林CORS系统的优、缺点。

Research on Line Measurement Technology Based on Jilin CORS

In this paper , line engineering survey is taken as study object based on CORS , and Changchun petrochemical gas pipeline project is a research background , the paper first introduces the features and functions of Jilin CORS system , and then analyzes the ap-plication mode in Jilin Petrochemical gas pipeline measurement based on CORS , on this basis, the paper discusses the operation meth-ods and implementation results , and error analysis .Through comparing precision between two methods of Jilin CORS system and con-ventional RTK measurement , the paper summed up the advantages and disadvantages in the Jilin CORS system .
