鞍山市连续运行参考站系统建设与定位精度分析

Construction on ASCORS and Analysis of Positioning Accuracy

介绍了连续运行参考站网络系统(CORS)的技术原理以及鞍山市连续运行参考站(ASCORS)系统的建设方法与结构功能。并利用ASCORS网络系统实测数据,分别从定位服务时效性、单点定位精度、动态精度、内外符合精度、内插与外推精度的分析入手,全面、有效地分析了CORS网络系统在其覆盖区域上的定位精度和可靠性。

This paper makes a detail introduction to the principle of Continuous Operational System (CORS),and describes the design and characteristics of Anshan Continuous Operational System (ASCORS).From the timeliness of positioning service,point-positioning precision,all kinds of dynamic positioning precision,the internal and external coincident precision,this paper comprehensively and effectively analyses the accuracy and reliability of the Continuous Operational Reference System (CORS) in its coverage by using the measured data of ASCORS,and it has the actual value and significance for the construction and useful of Continuous Operational Reference System (CORS).
