Indoor and Outdoor Joint Location Algorithm for Power Smart Supply Chain Park

For the power smart supply chain park, its business is complex and its area is huge. The single positioning system cannot meet the requirements of accurate positioning, and it is difficult to deal with some emergencies, resulting in unnecessary losses. This paper adopts the physical method of indoor and outdoor joint positioning connection, involving the GPS satellite positioning system, focusing on the positioning accuracy, realizing the seamless connection between the GPS system and the UWB positioning system, thus realizing the indoor and outdoor joint positioning, optimizing the system functions, and improving the security for power smart supply chain park.
