Background

Finland and Estonia issued a joint navigational warning for the Gulf in June 2025, after interference with satellite navigation rose sharply in the first half of that year (Xinhua, June 2025). A month later Estonia's technical regulator said four jammers stood between Narva and St Petersburg and that interference occurred daily (ERR, July 2025). For the reporting on interference in the Gulf of Finland, and who it is attributed to, see the Baltic Sea.

The Gulf of Finland is a sub-area of the Baltic Sea, not a country. Its figures count the hexagons whose centre lies in its box, 58.8° N to 60.8° N and 22.5° E to 30.5° E.

The Gulf of Finland is counted under the Baltic Sea.

Fewer receivers fed the map in its early years, so compare old and recent days with care: how far back the map goes.

The bold line is a rolling average; the pale line is each day. Days are UTC. The share is red and yellow hexagons as a fraction of all hexagons with enough aircraft that day. Download the series (JSON). How to read it.

The Gulf of Finland: low reported accuracy points to interference but does not prove it, and the map cannot locate a transmitter or say who is responsible. How the map is made.

Neutrality. We measure and describe data, it is not our job to take sides. The map records where aircraft lost position accuracy, which can come from jamming, spoofing, military testing, equipment faults or space weather. Our data alone can't say who is responsible, so we don't. When we mention a likely source, it's because a government, regulator or reputable outlet has said so publicly. That is their assessment, not ours, and we link to it. Region names and borders follow common international usage and imply no position on any dispute.
