Aviation Braces for Rising GPS Interference Amid Geopolitical Tensions

Aviation regulators are urgently addressing increasing disruptions to Global Navigation Satellite Systems (GNSS), essential for flight navigation. Recent incidents, particularly in volatile regions, prompt a collaborative plan to fortify aviation safety and system reliability.

Joint Action to Combat Interference

The International Air Transport Association (IATA) and the European Union Aviation Safety Agency (EASA) have unveiled a joint strategy to counter the growing threat of GNSS interference. This plan is a result of a workshop focused on interference issues.

The workshop determined that a wider and more coordinated approach is required to protect against disruptions. The strategy will focus on gathering better information, bolstering prevention measures, enhancing infrastructure and airspace management, and improving coordination among key agencies.

“GNSS disruptions are evolving in terms of both frequency and complexity. We are no longer just containing GNSS interference — we must build resilience. The evolving nature of the threat demands a dynamic and ambitious action plan,”

—Jesper Rasmussen, EASA Flight Standards Director

Reported incidents of GNSS interference, including jamming and spoofing, have been increasing. These disruptions have been observed in Eastern Europe, the Middle East, and other global locations. Initially, the focus was solely on managing individual incidents.

GPS Signal Losses Surge

According to IATA data, events involving global positioning system (GPS) signal loss surged by 220% between 2021 and 2024. This upward trend is likely to persist, given current geopolitical uncertainties.

The IATA and EASA are working together to strengthen system redundancies to maintain flight safety. The next step involves the International Civil Aviation Organization (ICAO) advancing these solutions with worldwide standards, guidance, and reporting protocols. These actions are expected to be prioritized at the ICAO Assembly later this year.

“IATA and EASA are working together to reinforce the redundancies that are built into the system, to keep flying safe,” said Nick Careen, IATA Senior Vice President, Operations, Safety, and Security. “The next step is for ICAO to move these solutions forward with global alignment on standards, guidance, and reporting.”
