摘　　要：CORS(Continuously Operating Reference Stations)对于促进测绘行业的发展起到了至关重要的作用。现今各城市基本上都已完成CORS系统的建设并投入运行,为了提高CORS的服务范围和性能,将多个城市CORS系统进行组网。文章论述了CORS系统的组成和优势,探究大规模CORS系统的性能测试方案。以某地区的组网CORS系统为例,分析该CORS系统的定位精度、空间可用性、时间可用性和系统的兼容性,进而对其性能做出分析评价。Abstract： CORS （Continuously Operating Reference stations） plays a vital role in promoting the development of surveying and mapping industry. Today all of the cities have been completed CORS system construction and put them into operation. In order to improve the service scope and performance of CORS, some cities put CORS system together. This paper narrates the composition and advantages of CORS system, then explores the performance testing scheme of large-scale CORS system. Taking a networking CORS system in a region as an example, this paper analyzes the position precision, space availability, time availability and compatibility of the system of the CORS system, and finally analyzes and evaluates its performance.
