The paper describes the application of GPS multi-antenna system to the safety monitoring of 2 # slope of the Xiaowan Hydropower Station. The Xiaowan Hydropower Station is located in a deep valley, so there are restrictive factors on GPS positioning accuracy of slopes, such as geographical environment, climatic condition, and so on. The present study has found out the problems which restrict the application of GPS and solved them from the respects of hardware development and positioning algorithm of the system, and thus realized the GPS automatic safety monitoring of 2 # slope.
