基于北斗的PPP-RTK技术在无人机电力巡检中的应用分析OA北大核心

In order to solve the problem that high-precision positioning service is not available for UAV power inspection in areas with no public network or complex terrain conditions,this paper proposes to use precise point positioning-real-time kinematic(PPP-RTK)technology based on BeiDou Navigation Satellite System(BDS)to provide high-precision positioning service for UAV power inspection.Using data from the electric power BeiDou precise positioning service network in Sichuan province to calculate the PPP-RTK server-side product and conduct user-side simulated dynamic positioning experiments.The experimental results show that under the conditions of using BDS-based PPP-RTK services,when the user-side adopts BDS or BDS+GPS for PPP-RTK integer ambiguity resolution,convergence can be achieved within 1 minute.After convergence,the horizontal direction root mean square(RMS)is less than 5 cm,and the vertical direction RMS is less than 8 cm.The experimental results can provide design reference for the construction of power BeiDou PPP-RTK service and its application in UAV inspection.
