合肥市卫星定位连续运行基准站网融合改造的实践探讨

Practice and discussion on integration transformation of satellite positioning continuous operation reference station network in Hefei

为了更好地服务于自然资源和规划,建立合肥市统一的卫星定位连续运行参考站(CORS).针对当前合肥市三套卫星定位CORS独立运行、基准框架和服务标准不统一的问题,从基准站深度融合建设、系统软硬件升级、现有软硬件的兼容性、组网设计和CORS基准框架坐标联测与扩展服务的实践展开探讨.综合运用了多种共享融合技术,通过外业实测验证方法的正确性和可行性,对城市CORS融合改造具有很好的借鉴意义.

Aiming at the problem that three sets of continuously operating reference stations(CORS)systems in Hefei operate independently and the benchmark framework and service standards are not unified,A unified satellite positioning continuous operation benchmark station network in Hefei is established in order to serve natural resources and planning better.This paper discusses the deep integration construction of reference station,the upgrading of system software and hardware,the compatibility with existing software and hardware,networking design,and the practice of CORS benchmark framework coordinate joint measurement and expansion service.A variety of shared integration technologies are comprehensively used to verify the correctness and feasibility of the method through field measurement,which has a good reference significance for the integration transformation of urban CORS.
