BeiDou navigation satellite system is a self built and independently operated satellite navigation system in China, which provides all-weather, all-time, high-precision positioning, navigation and timing services. In order to meet the demand of high-precision time service, positioning, navigation and other applications of power grid business, this paper analyzes the technical conditions and requirements of the ground-based augmentation system construction, and combines the resource conditions of State Grid Shandong Electric Power Company. Based on the research on the site selection of base station, the construction of observation pier, system power supply, system lightning protection, communication access and safety protection, the solution of the ground-based augmentation system of Beidou precision service network is given, which can also provide reference for other similar projects.
