Estonia and the Gulf of Finland see frequent interference tied to activity around the Russian border.
Check the live reading above and open the map. FLYAWAY reads GPS accuracy from the aircraft over Tallinn and refreshes every few minutes.
When the reading is high, treat GPS near Tallinn as unreliable: keep the drone in sight, be ready to fly manually, and do not rely on return-to-home. When it is severe, do not fly.
Estonia and the Gulf of Finland see frequent interference tied to activity around the Russian border.
Tallinn overlooks the Gulf of Finland from Estonia's northern coast, connected to Helsinki by a busy ferry route across the water. It lies roughly 240 km from the Russian border east of the Gulf of Finland, the direction from which near-daily interference is reported, exposing its harbour traffic and airport approaches to the disruption recorded across these waters.
Finland and Estonia have reported near-daily GPS interference over the Gulf of Finland since 2022, prompting warnings from both countries' aviation authorities. In 2024, authorities noted disrupted airline approaches at eastern airports. Tallinn lies within this affected corridor, where degraded satellite signals have become a routine consideration rather than an isolated event for those operating in the region.
Estonia's capital is a busy Baltic ferry port and a well-known digital-economy and e-government centre, served by an international airport that relies on satellite navigation. Ferries crossing to Helsinki and aircraft on approach both depend on accurate positioning, so interference over the Gulf of Finland carries direct consequences for the transport links the city's economy is built around.
