Application of BeiDou Navigation Satellite System Based Indoor and Outdoor Fusion Positioning Technology in the Construction of Power Grid Substations

This paper proposes a technical solution for indoor and outdoor fusion positioning. This paper studies the algorithm principles of two positioning modes, satellite positioning and ultra-wideband indoor and outdoor fusion positioning, and proposes a high-precision positioning algorithm that is compatible with the two positioning modes. This paper adopts the innovative development of the innovative rail terminal mobile platform, night patrol module, and switching function module. The system can better play the practical use of substation robots. The actual test shows that the system has the characteristics of complete functions, accurate positioning, and stable operation. The system provides an essential solution for the intelligent management and safe production of the State Grid.
