INT’L FEDERATION of Air Traffic Controllers’ Associations and the Int’l Federation of Air Line Pilots’ Associations were tapped to help ramp up international visibility on the rising impact of RFI to GNSS, aviation officials in a regional planning group said.
January 7, 2025

New “symptoms” appear to be emerging in the “huge” spike in RFI, and which extend to loss of certain RLAN data connectivity for antenna beam steering, loss of SATCOM functionality, a cascade effect from incorrect timing, certain instances of autopilot unavailability, and weather radars: tally on GNSS RFI and spoofing from an airline company’s manager of technical flight operations.
A POST-WRC-23 readout added an early data point to the evolution of urgency in consideration of “necessary measures” to spur operation of earth stations onboard unmanned aircraft used for C2 links, and operated in non-segregated airspace using satellite AMS(R)S, a report indicated.
