Wireless charging of unmanned aerial vehicles

A method for charging aerial vehicles by a charging pad comprising:

• determining, by a controller circuit, a location of one or more aerial vehicles and/or one or more legs of the one or more aerial vehicles relative to the charging pad based on a pattern of a plurality of received sense voltages;
• producing, by one or more driven coils of at least one sensing tile of an array of sensing tiles in communication with the controller circuit, magnetic signals in response to drive coils, wherein each sensing tile of the array of sensing tiles includes the one or more of the driven coils;
• receiving, by one or more passive sense coils of the at least one sensing tile of the array of sensing tiles, at least one of the magnetic signals produced by the driven coils, wherein each sensing tile of the array of sensing tiles includes the one or more of the sense coils;
• producing, by the one or more sense coils of the at least one sensing tile of the array of sensing tiles in communication with the controller circuit, at least one of the sense voltages as a function of a proximity of the at least one sensing tile to one of the one or more aerial vehicles and/or one of the one or more legs of the one or more aerial vehicles;
• and
• delivering power, by at least one charging coil of an array of charging coils, to the one or more aerial vehicles and/or the one or more legs of the one or more aerial vehicles positioned at the location determined by the controller circuit, wherein the array of charging coils forms a layer separate from and stacked with respect to the array of sensing tiles.
