Southwest Finland and the Archipelago Sea see frequent GPS interference drifting across the Baltic, tied to activity near the Russian border.
Check the live reading above and open the map. FLYAWAY reads GPS accuracy from the aircraft over Turku and refreshes every few minutes.
When the reading is high, treat GPS near Turku 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.
Southwest Finland and the Archipelago Sea see frequent GPS interference drifting across the Baltic, tied to activity near the Russian border.
Turku sits on Finland's south-western coast at the edge of the Archipelago Sea, a shipbuilding centre and busy ferry port near the mouth of the Aura River. It lies roughly 340 km from the Russian border east of the Gulf of Finland, the source of the region's reported interference, placing its ferry lanes and airspace within the wider affected area.
Near-daily GPS interference over the Gulf of Finland has been reported by Finland and Estonia since 2022, prompting warnings from Finnish aviation authorities and, in 2024, disrupted airline approaches at eastern airports. Turku belongs to this affected region, where operators increasingly treat degraded satellite positioning as a standing possibility rather than a rare event.
Finland's oldest city is a major shipbuilding centre and Archipelago Sea ferry port, with shipyards, ferry services and aviation all relying on satellite positioning. Because the dense island waters around Turku demand precise navigation, interference can complicate ferry routing and coastal operations, giving the city's maritime and aviation sectors a direct interest in reliable GNSS.
