Abstract: To realize the continuous automatic monitoring of the landslide bodies of Xiluodu hydropower station, the automatic monitoring system based on BeiDou navigation and positioning system is established and the data calculation software HCMonitor is adopted. The combination of GPS, GLONASS and BeiDou system can greatly increase the reliability and accuracy of positioning, especially for the observation points in adverse environment. By use of BeiDou navigation and positioning system, the system stability and data accuracy are guaranteed and its application in slope monitoring in reservoir area is exploited, which provides reference for similar high-precision automatic deformation monitoring systems.
