An Induction-Based Localisation Technique for Wirelessly Charged Drones

This manuscript proposes a technique to use an inductive power transfer system to perform last-stage localisation of drones for tracking and automated landing. This system is proposed to assist the final stage of landing by solely making use of the inductive charger and avoid using vision or other external sensors which would increase cost and complexity.The simplicity of the proposed method can help widen the practical implementation of automated drones. This proposed method is demonstrated with a high frequency (6.78 MHz) inductive charging system that can deliver up to 100 W of power to a DJI M100 drone when it lands at any position on the designed one-meter diameter charging pad.
