Joint positioning method of Beidou RTK and UWB in transformer substation based on coordinate calibration

Abstract： The complex environment of transformer substation puts forward higher requirements for positioning. In this paper, a joint positioning method is proposed. Combined with the advantages of high-precision positioning of Beidou RTK in the outdoor area and UWB in the indoor area, the absolute coordinates of the indoor UWB base station are solved by calibrating the reference points, so that the indoor positioning and outdoor positioning are unified into the same coordinate system, and the handover criterion is adopted in the transition area to realize the smooth transition of the two systems. Through the field test in the substation, it shows that the proposed positioning method can achieve stable positioning in the indoor and outdoor complex environment, and the positioning accuracy is good, which can meet the positioning requirements of the daily work of the substation.

Key words : transformer substation; indoor and outdoor positioning; Beidou RTK; ultra wideband positioning; coordinate calibration
