The recurrent GPS interference at Tartu Airport, attributed to deliberate signal scrambling efforts amid geopolitical tensions, has seriously impacted the airport's flight operations. Finnair halted its Tartu route for one month to investigate and remedy the interference. Aviation expert Sven Kukemelk highlighted that ongoing unresolved GPS jamming could lead to Finnair permanently ceasing flights to the airport, threatening Tartu's connectivity and regional transport infrastructure. Authorities anticipate that fully restoring reliable air traffic control services could take months. The disturbances reflect broader hybrid warfare tactics involving cyber operations targeting critical infrastructure, complicating air navigation safety and commercial flight operations in Estonia.
