Abstract: At present, the external deformation monitoring of hydropower stations is still mainly carried out by traditional manual methods. Research on the testing and application of Beidou high-precision de⁃ formation monitoring technology was conducted in Tianhuangping pumped storage power station. Focus⁃ ing on the specific monitoring scenarios of hydropower dams, starting from improving the receiving equipment and algorithm of the domestic Beidou satellite navigation system for high-precision deforma⁃ tion monitoring, the existing monitoring system has been upgraded and improved. Through the compari⁃ son of dynamic loading displacements, Beidou calculation results and traditional manual observation re⁃ sults, the applicability of the domestic Beidou system in the deformation monitoring of hydropower dams has been verified.

Key words: Beidou, deformation monitoring, testing
