摘 要：This article first introduced the architecture, data processing flow, data processing strategies and data processing results of HNCORS GNSS online differential data processing system, and then analyzed the precision, repeatability and stability of the system by processing the GNSS data of datum stations and measured stations. Finally, based on the simulation deformation monitoring experiment, the feasibility of system application in deformation monitoring was discussed in this article. The experimental results showed that the repeatability and stability of the system is high, which can provide cm or mm level positioning services for Hunan Province GNSS users. What’s more, the system has broad application prospects in deformation monitoring.
