    Abstract
  • 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.
