On 3 November 2026, aircraft operating along most of NATO's eastern flank reported widespread satellite navigation interference, with strong GPS jamming and related GNSS degradation forming a near-continuous band from the southern Baltic Sea to the western Black Sea. The pattern was documented by the Italian flight-tracking project ItaMilRadar using AirNav Radar aircraft data and published in a jamming map shared on 4 November 2026. The heaviest interference was observed over the Baltic coast near Russia's Kaliningrad exclave, along Poland's borders with Belarus and Ukraine, over Romania and Moldova, and along Bulgaria's Black Sea coast, with lighter interference along air routes across Belarus and western Russia, around Crimea, and in the Caucasus. The jamming pattern closely follows border regions crossed by Russian attack drones during strikes on Ukraine and may partly reflect counter-drone jamming by NATO states, but no government has publicly claimed responsibility or confirmed activity on this scale. The article references prior research that located Russian GNSS jamming and spoofing sources in Kaliningrad and around St. Petersburg and notes that Sweden and five neighboring countries informed the International Civil Aviation Organization in early 2025 that approximately 123,000 flights over Poland, the Baltic states, Finland, and Sweden experienced interference traced to Russian territory, including Kaliningrad, St. Petersburg, Smolensk, and Rostov. The piece also recalls multiple Russian drones straying into NATO territory, including a September 2026 incident in which a Russian drone flew deep into Romania before crashing in Moldova, and highlights Russia's extensive electronic warfare capabilities, such as mobile jammers and the Infauna electronic warfare vehicle, which has been observed as far afield as Mali.
