The laser powered UAV can achieve real-time energy supply and enhance the duration of UAV.Usually,UAV flies far from the ground fixed supply station,and the laser spot increases to cover the UAV body completely,which leads to the long distance of wireless energy transmission,and inability to implement laser tracking and aiming.In order to solve the above problems,a new tracking and aiming method is proposed in this paper.According to the comparison of the output voltage of photosensitive sensors installed on photovoltaic panels,the UAV can be tracked optimally.It is calculated that the offset tracking east-west direction is 2.310 mm,which is approximate to the actual offset 2 mm,and the error is 0.31 mm.
