摘　　要：随着北斗卫星导航系统的组网建设完成,北斗卫星导航系统的定位精度和应用能力逐步增强,基于北斗增强的CORS系统组网建设具有重要意义。本文依托于南雄市区域CORS系统的建设项目,介绍了CORS系统基站布网、基站建设、精度统计、检验等内容,并从时间和空间可用性、RTK定位精度、初始化等方面测试CORS系统的应用效果。结果表明:系统网内和网外精度分布均匀,三星系统流动站平均收敛时间为9.5s,系统全天的时间可用性达到96.71%,固定解范围能覆盖南雄市全域,可提供厘米级RTK定位服务。With the completion of the Beidou satellite navigation system network construction,the positioning accuracy and application capabilities of the Beidou satellite navigation system are gradually enhanced.The construction of the CORS system network based on the Beidou enhancement has great significance.This article relies on the construction project of CORS system in Nanxiong,introduces the contents of CORS system base station network deployment,base station construction,accuracy statistics,inspection,etc.,and tests the application of CORS system in terms of time and space availability,RTK positioning accuracy,initialization,etc.The results show that the accuracy distribution of the network inside and outside the system is even,the average convergence time of Samsung Rover is 9.5 s,the system’s time availability is 96.71%,the fixed solution range can cover the entire Nanxiong,and it can provide centimeter-level RTK positioning services.
