Safe powering of tethered drone

Abstract

A drone includes a propulsion system, a processing unit, and a power system having a battery and a power connection port. The power system is configured to receive packetized electrical power over a tether including an air-to-ground power feed attachable to the power connection port. The power system is also configured to supply electrical power to the processing unit, the battery, and the propulsion system. The processing unit is configured to acknowledge receipt of the packetized electrical power. A power delivery system includes a packetized electrical power transmitter and a processing unit. The processing unit is configured to operate the packetized electrical power transmitter to transmit packets of electrical power over a power feed within a tether attached to a drone. The processing unit is also configured to monitor a communication channel within the tether for acknowledgements indicating the drone has received the transmitted packets of electrical power.
