Aviation authorities report GPS interference spreading across high-risk airspaces including the eastern Mediterranean, Black Sea, Russia-Baltic region, India-Pakistan border, Iraq, Iran, and Korean peninsula, prompting updated guidance from US and European regulators.
The FAA released Version 1.1 of its GPS and Global Navigation Satellite System Interference Resource Guide, heavily revised from an earlier 2026 edition. It covers jamming and spoofing trends, aircraft system effects, pilot procedures, and training recommendations. The update incorporates feedback from the FAA’s Performance Based Operations Rulemaking Committee GPS/GNSS Disruption Action Team, including input from the National Business Aviation Association (NBAA).
Richard Boll, chair of NBAA’s Airspace and Flight Technologies Subcommittee, stated the guide targets pilots, operators, and avionics manufacturers. Because this version is so significantly revised, stakeholders familiar with the previous version should review the new guide and implement recommendations appropriate to their operation, Boll said. He noted interference is no longer limited to geopolitical hotspots, citing a 2022 incident near Denver where an unauthorized transmitter disrupted GNSS for flights, air traffic control, and other systems. The guide emphasizes reporting events, detailing affected equipment and actions taken.
In Europe, EASA and Eurocontrol published a joint action plan to coordinate responses. It aims to merge monitoring and operational data for better detection, reporting, and awareness, providing consistent guidance to airlines, air navigation providers, and authorities. The plan follows a June 2025 letter from 13 EU states on rising interference, with Eurocontrol highlighting safety and airspace capacity risks.
