摘　　要：针对CORS系统建设中选址、通信等问题,本文以深圳市北斗CORS为例,根据深圳地质情况进行选址建站,通过构造网络、设计系统等方法建立基于北斗卫星的深圳市北斗CORS系统,利用野外实测方法对北斗CORS系统进行实时定位精度、内符合精度、可用性及数据有效性测试,结果表明深圳市北斗CORS系统不但在平面上可提供5 cm级位置服务,而且在高程上提供10 cm的位置服务,系统的数据有效率超过95%,可为深圳市经济发展建设提供稳定的测绘基准。Aiming at the problems of site selection and communication in the construction of CORS system, this paper takes Shenzhen Beidou CORS as an example, builds stations in combination with the geological conditions of Shenzhen, establishes Shenzhen Beidou CORS system based on Beidou satellite through network structure and system design, and tests the real-time positioning accuracy, internal coincidence accuracy, availability and data effectiveness of CORS system by using field measurement method, The results show that Shenzhen Beidou CORS system can provide 5 centimeter level location service on the plane, and the data efficiency is more than 95%,which can provide a stable surveying and mapping benchmark for the economic development and construction of Shenzhen.
