Compared with the sunlight charging, unmanned aerial vehicle (UAV) laser charging can improve the power of charging energy and the continuous charging performance. The accuracy of automatic tracking aiming is a key indicator of UAV laser charging. Based on the working principle and components of laser charging system, the precision of laser charging tracking was analyzed. Based on establishing the UAV laser tracking charging model, various error factors affecting the tracking accuracy were analyzed, and the effect of each single error change on the azimuth angle and zenith angle of comprehensive error was analyzed. On the basis of reasonable error distribution, the comprehensive error of azimuth angle and zenith angle of laser tracking charge was obtained. Analysis on the tracking precision can provide theoretical reference for the subsequent calibration.
