Estonian commander attributes increased GPS jamming in Baltic region since 2023 to Russia, raising aviation safety concerns and indicating Moscow is testing electronic warfare capabilities.
Starting last year, instances of GPS signal jamming and spoofing have intensified in Eastern Europe and the Baltic states, disrupting satellite navigation used by airlines, smartphones, and military systems. Martin Herem, commander of the Estonian Defense Forces, publicly accused Russia of this jamming, noting it aligns with Moscow's prior electronic warfare exercises in Kaliningrad and reported efforts from ships in the Baltic Sea. The Russian Defense Ministry has acknowledged training for electronic signal disruption. This activity is part of growing Russian electronic warfare efforts observed in Ukraine and northern Europe. European aviation authorities, including those from Poland, Sweden, and Finland, are investigating these interference reports due to concerns over commercial flight safety. NATO allies have increased their awareness of Russia’s military capabilities in ammunition production and troop recruitment, prompting warnings and preparations for a potential protracted conflict. The European Aviation Safety Agency highlighted the urgent need for crew training to cope with this emerging threat.
Confidence: High
The event clearly describes Russian hostile electronic warfare activities causing GPS jamming in the Baltic region, identified by the Estonian Defense Forces commander, constituting aggressor activity; concurrently, European aviation authorities and NATO allies are responding with warnings and countermeasures, indicating defense preparations.
