Summary

In late March 2024, GPS jamming incidents blamed on Russia disrupted aviation navigation across the Baltic Sea region, forcing two Finnair flights from Helsinki to Tartu on consecutive days to return to Finland due to inability to safely navigate. The jamming also affects maritime navigation, with warnings issued by the Swedish navy. Baltic foreign ministers from Estonia, Latvia, and Lithuania condemned these acts as hostile hybrid warfare activities threatening civilian safety. The interference reportedly originates from multiple sources, including mainland Russia and the Kaliningrad exclave. UK officials confirmed a similar GPS jamming incident affecting a government plane near Kaliningrad in March 2024. Experts warn of rising accident risks due to reduced reliance on GPS. While some consider it a serious safety threat, Finnair cites increasing nuisance without immediate safety impact, noting limited GPS-dependent airports such as Tartu. Baltic officials continue consultations with NATO allies and urge cessation of jamming to protect civilian aircraft.

Classification

Confidence: High

Classified as aggressor signal because multiple official sources and ministers in Baltic states attribute GPS jamming and navigation interference to Russia as hostile hybrid warfare actions threatening civilian flights. Classified as defense prep signal as Baltic officials are engaging allies, discussing safety risks, and calling for countermeasures against the interference.
