Radio waves emanating from secretive facilities run by Russia’s military are the culprit behind GNSS jamming in the Baltic Sea, according to Defense News.

The news outlet reports that Polish researchers collected jamming and spoofing information on incidents covering the Gdansk airport, shipping lanes, and the airspaces of Estonia and Finland. The interference has been recorded almost daily since Russia’s full-scale invasion of Ukraine in February 2022, resulting in flight cancellations, airport closures and commercial ships steering off track.

In March, eight European countries, including the Baltic states, Finland, Poland, France, the Netherlands and Ukraine, lodged a complaint with the UN about the practice. Several UN agencies have also taken up the issue, including the International Maritime Organization, the civil aviation authority ICAO and the International Telecommunications Union.

Russia, itself a Baltic Sea country, has not responded to the charges of interference. Likely origin spots include Kaliningrad, which is between Poland and Lithuania, and the St. Petersburg area. Both regions are known to have a heavy Russian military presence, including divisions specialized in electronic warfare.
