Baltic Region Airspace
FIR: EETT (Tallinn) / EVRR (Riga) / EYVL (Vilnius) · Last updated: April 2026
Current Status
The Baltic FIRs (Estonia EETT, Latvia EVRR, Lithuania EYVL) and adjacent Finnish airspace experience persistent GPS jamming originating from the Russian exclave of Kaliningrad. This electronic interference has been ongoing since 2022 and has intensified through 2024-2026, affecting both en-route navigation and approach procedures.
Finnair suspended its Tartu route in 2024 specifically due to GPS jamming making GPS-dependent approaches unsafe. Other airports in the region that rely on GPS/RNAV approaches have implemented ILS-only procedures or enhanced monitoring. The jamming affects an area extending roughly 300 kilometers from Kaliningrad.
Despite the GPS interference, the Baltic FIRs remain fully operational with standard ATC services. The risk is primarily to navigation accuracy rather than airspace access. However, the persistent nature of the interference has forced airlines to adapt their operational procedures for the entire region.
Key Risks
Russian electronic warfare from Kaliningrad causes continuous GPS degradation across the Baltic states, affecting RNAV procedures.
Airports dependent on GPS approaches face operational restrictions; some routes suspended due to inability to fly RNAV approaches safely.
GPS position errors can trigger false Ground Proximity Warning System alerts, creating cockpit distraction during critical phases of flight.
GPS jamming intensity serves as a leading indicator of regional tensions, with spikes correlating to military activity.
Recent Events
GPS jamming intensity increased over Easter weekend, affecting flights across Estonia, Latvia, and Finland.
EASA published updated guidance on GPS jamming mitigation for operators in Baltic airspace.
Finnair confirmed permanent suspension of Tartu route due to persistent GPS jamming making GPS approaches unsafe.
NATO reported GPS jamming from Kaliningrad at highest sustained levels since monitoring began.
EASA & FAA Guidance
EASA has published Safety Information Bulletins (SIBs) addressing GPS jamming in the Baltic region, advising operators to verify ILS capability at destination airports and maintain contingency procedures for GPS loss. The FAA has issued advisory guidance for US operators flying through the region. Neither authority restricts operations, but enhanced awareness is recommended.
