EASA and IATA unveil joint plan to tackle GNSS interference threats

The European Union Aviation Safety Agency (EASA) and the International Air Transport Association (IATA) have launched a comprehensive action plan to counter the growing threat of GNSS (Global Navigation Satellite System) interference, following a high-level workshop in May.

With GNSS jamming and spoofing incidents rising sharply, especially in Eastern Europe and the Middle East, the plan shifts the focus from mere containment to building system-wide resilience.

The plan centres on four key areas:

1. Enhanced Reporting & Monitoring

   • Standardised radio calls and NOTAM codes for GNSS threats

   • Real-time airspace monitoring and faster information sharing

2. Prevention & Mitigation

   • Tighter controls on jamming device availability

   • Development of portable spoofing detectors and improved GPS recovery solutions

3. Infrastructure & Airspace Management

   • Strengthening backup navigation systems

   • Leveraging military air traffic tools for GNSS monitoring

   • Updated contingency procedures for safe navigation during outages

4. Coordination & Preparedness

   • Stronger civil-military coordination and data sharing

   • Proactive measures to address evolving threats, including those involving drones

IATA noted a 220% rise in GPS signal loss events between 2021 and 2024, citing geopolitical tensions as a likely cause. Both agencies called on ICAO to adopt global standards and ensure GNSS safety is a top priority at its upcoming assembly.

Over 120 international experts participated in the Cologne workshop, highlighting the urgency for a unified, global aviation response.
