Research and Application on Cooperative Positioning Technology in Substation Project based on BDS and UWB

Abstract

Abstract This article mainly discovers and studies a cooperative positioning technology which combines Beidou Navigation Satellite System (BDS) and Ultra Wide Band (UWB) technology. BDS is mainly used for precise positioning in outdoor environments, and UWB technology can be widely used for positioning in both indoor and outdoor environments. This article firstly proposes a combined positioning technology based on BDS and UWB positioning technology, and proposes appropriate technical schemes and solutions for outdoor, indoor and indoor-outdoor transition areas. After considering the actual situation of the substation project, a coordinate conversion method that can be applied in the actual engeerning project is proposed to realize the unification of different coordinate systems and meet the needs of seamless positioning of indoor and outdoor panoramic views of the substation project. Finally, the field test results proves the effectiveness of proposed method.
