摘要： 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).

摘要： A system and method for adaptive extension of a command and control (C2) backhaul network for unmanned aircraft systems (UAS) is disclosed. In embodiments, the adaptive extension includes front-end and back-end cognitive engines on either side of an extension of the C2 backhaul network to a remote control station otherwise without a point of presence (PoP). Both cognitive engines transmit test packets to the other to refine coding schemes for transmission of C2 packets across the extension based on received feedback about the transmission. When C2 packets are received from the backhaul network or remote control station, the cognitive engines select an optimal coding scheme based on packet size. The cognitive engine encodes the C2 packets based on the optimal coding scheme. When C2 packets are received from the other cognitive engine, the applicable coding schemes are identified and the C2 packets decoded accordingly.
