System and method for spectrum situational awareness via server-based fusion in a command and control (C2) link system for unmanned aircraft systems (UAS)
System and method for spectrum situational awareness via server-based fusion in a command and control (C2) link system for unmanned aircraft systems (UAS)
A centralized spectrum arbitrator for a command and control (C2) link system is disclosed. In embodiments, the spectrum arbitrator receives sensor fusion data from the air radio systems (ARS) and ground radio systems (GRS) of the C2 link system, each dataset comprising mean energy levels for a particular frequency and location. The spectrum arbitrator determines a time average of the energy levels and evaluates interference with the frequency at the location (e.g., whether the interference is tolerable or the frequency should not be used) and attempts to classify interfering signals (e.g., as radar, malicious, of the C2 link system or competing). The spectrum arbitrator may further fuse sensor fused data into additional spectrum situational awareness (SA) outputs illustrating or recommending opportunistic frequency use or reuse across the C2 link system.
