1. A system for airborne radio frequency (RF) profile generation, comprising: at least one processor communicatively coupled to one or more avionics systems aboard an aircraft, the at least one processor configured to: receive at least one absolute position of the aircraft generated by a satellite-based navigational receiver of the aircraft, the absolute position including at least a timestamp, a latitude, and a longitude; receive, from an aircraft-based altimeter, at least one altitude of the aircraft: receive, from a navigational system of the aircraft, at least one VOR/DME position fix including at least one of:
a bearing angle of the aircraft corresponding to a VHF (Very High Frequency) omnidirectional range (VOR)/Distance Measuring Equipment (DME) ground station;
or
a distance between the aircraft and the VOR/DME ground station: receive, from a communications management unit (CMU) of the
aircraft, at least one avionics communication link identifier comprising:
a station identifier (SID) corresponding to a ground control station configured for establishing a communications link to the aircraft:
and
a link quality indicator indicative of a signal strength of the communications link; and generate at least one RF profile corresponding to each absolute
position by correlating the altitude, the VOR/DME position fix, and the
avionics communication link identifier associated with the timestamp of the absolute position; and at least one memory coupled to the processor, the memory configured for
storage of the generated RF profile.
