Abstract: 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.
