“AHCORS”在国家地下水监测工程建设中的应用研究

A STUDY ON APPLICATION OF“AHCORS”IN THE CONSTRUCTION OF NATIONAL GROUNDWATER MONITORING PROJECTS

随着区域连续运行卫星定位综合服务系统(CORS)在高精度的区域似大地水准面基准上的技术发展越来越成熟,服务范围越来越宽,服务水平越来越高,在实际工程中的应用也越来越多。文章基于地下水监测站点工程所要求的常规测量方法无法实施的D级GPS高精度平面点位和高程的测定,采取利用AHCORS加以解决,成果精度分析与验证表明,各项指标满足规范与设计要求。

With the ever-increasing maturity of the Continuously Operating Reference Stations(CORS)on the high-precision regional quasi-geoid datum,its service scope is getting wider and service level getting higher than ever,and is more and more applied in engineering examples.Considering the determination of D-level GPS high precision plane point position and elevation required by the groundwater monitoring station project,which cannot be implemented by the conventional measurement method,this paper adopts AHCORS(CORS of Anhui Province)to solve the problem.The analysis and verification of the accuracy of the results show that each index meets the requirements of the specification and design.
