Abstract
An unmanned aerial system (UAS) is disclosed. In embodiments, the UAS includes an unmanned aerial vehicle (UAV), and a controller communicatively coupled to the UAV. In embodiments, the UAS controller may be configured to: acquire a command and control (C2) link quality model for a planned route; generate one or more control signals configured to cause the UAV to perform a monitored flight along a planned route; acquire actual C2 link quality data during the monitored flight along the planned route; compare the actual C2 link quality data to the C2 link quality model; identify a C2 link quality deviation between the actual C2 link quality and the C2 link quality model; and generate one or more control signals configured to cause the UAV to perform one or more prescribed flight plan maneuvers if the identified C2 link quality deviation (ΔC2LQ) exceeds a threshold deviation value (C2thresh).
