Abstract
The invention consists of a system allowing remote wireless transfer of energy from a base station to a moving object, in particular a drone, moving in a given zone around the base station. The system includes means for tracking the moving object so as to determine the position of the moving object relative to the base station at any time, means for transmitting a synthetic acoustic wave focused in the direction of the moving object, these two means being located at the base station and powered by the base station, and acoustic reception means, located on the moving object, for receiving the acoustic wave transmitted by the base station and converting the received acoustic wave into an electrical signal and then into a power supply voltage for a battery.
