US Patent 11747832 Unmanned aerial vehicle (UAV) systems and methods for maintaining continuous UAV operation

An unmanned aerial vehicle (UAV) system for maintaining UAV flight continuity, includes a ground station, a first UAV, a second UAV, a processor, and a memory. The memory contains instructions thereon, which, when executed by the processor in response to receiving a remaining battery charge signal from the first UAV, selectively deploy the second UAV from the ground station when the remaining battery charge signal indicates that a remaining battery charge of the first UAV is below a threshold value, and return the first UAV to the ground station.
