EASA and Eurocontrol Publish GNSS Joint Action Plan

Amid growing threats of Global Navigation Satellite System (GNSS) interference, the European Union Aviation Safety Agency (EASA) and European air traffic management provider Eurocontrol have outlined a series of measures that they hope will help operators “strengthen the robustness of GNSS-based operations.”

Eurocontrol director general Raúl Medina described GNSS interference as “a significant and evolving challenge for European aviation.” Accordingly, the newly published joint action plan “focuses on maintaining safety in the near term while limiting impacts on airspace capacity and containing the threat of GNSS interference,” explained Eurocontrol.

By pooling their collective monitoring capabilities and operational data, the partners hope to build a “common, validated operational picture of GNSS interference events across Europe, enabling more accurate detection, reporting and situational awareness,” they explained.

This will help the parties develop what Eurocontrol termed “consistent and harmonized guidance” to air navigation service providers, airlines, and national authorities, which in turn will “ensure rapid and aligned responses to interference events.”

The action plan has been drafted in response to a letter sent in June 2025 by 13 EU member states, highlighting an increasing number of radio frequency interference events—such as jamming and spoofing—affecting GNSS-based systems.
