Research on the Joint Positioning Method of Beidou RTK and UWB Substations Based on Coordinate Calibration
To meet the positioning requirements in the complex environment of substations and ensure the accuracy of on-site positioning results in substations,this paper combines the respective advantages of Beidou RTK and UWB positioning technologies to complete the design of a joint positioning method for Beidou RTK and UWB substations based on coordinate calibration.Firstly,the Beidou RTK and UWB positioning technologies are introduced in relation to the current construction situation of substations.Secondly,a joint positioning method for Beidou RTK and UWB substations based on coordinate calibration is designed from three aspects:real-time dynamic measurement analysis,indoor-outdoor integrated positioning model design,and indoor-outdoor high-precision joint positioning system design.Finally,the effectiveness of the joint positioning method is verified,and the results show that the joint positioning method in this paper has high effectiveness and reliability,which not only guarantees the stability of substation positioning but also improves the accuracy of substation positioning,fully meeting the positioning needs of indoor and outdoor complex environment substations.
