Persistent aerial reconnaissance and communication system

This invention describes a drone that can fly for extended periods by drawing power through a tether connected to a ground station. The drone converts high-voltage power from the tether to operate its motors, while also carrying a battery for backup or supplementary power. A specialized system on the ground manages the tether, deploying it as the drone flies and retracting it, allowing the drone to operate from a mobile or stationary base.

Why it matters: Since 2017, advancements in power electronics and battery management systems have made high-voltage tethered power delivery and efficient power allocation more practical and robust. This improves the feasibility of persistent, long-duration drone operations described in the claims.
