Finnair suspends flights to Tartu Airport in eastern Estonia after repeated GPS-signal disruption.
The Finnish carrier Finnair announced it would suspend its daily flights to Tartu from 29 April until 31 May because two recent flights had to divert back to Helsinki after GPS signal interference prevented safe approaches to Tartu’s runway. Tartu lies close to the Russian border (about 40 km) and its flight paths traverse the Gulf of Finland—a region where GPS jamming and spoofing have been repeatedly reported. Sweden, Finland and Estonia have pointed to increased GNSS interference emanating from Russia’s Kaliningrad and Saint Petersburg military areas. The dynamics reflect this approach: by disrupting GPS signalling, the adversary forces airlines and civil-aviation authorities to invest in alternative landing systems, divert resources to resilience, and create operational uncertainty near a NATO state. Estonia’s Foreign Minister accused Russia of violating international regulations through this interference and said the matter would be raised with NATO and EU partners. Although no formal public attribution to the Russian Federation was made in Finnair’s statement, the pattern of GPS-jamming in Eastern Europe since 2022 matches other Russian-linked hybrid-operations. The episode underscores that Estonia are vulnerable not only to physical incursions but to electronic -navigation domain attacks that sit just under the threshold of open conflict.
