The Baltic Sea region has experienced significant electronic interference and signal manipulation, which officials have attributed to Russia. The German Navy reported an increase in the disruption and falsification of radio signals, describing the area as a “land of plenty for electronic anomalies.” This interference has impacted maritime navigation, including an incident where a passenger ship traveling toward Finland could not reliably determine its position via satellite data.

Beyond maritime concerns, the interference has escalated into a major safety threat for civil aviation. Pilots operating near Finland and the Baltic states report frequent disruptions to critical GPS signals used for determining altitude, speed, and position. Experts note that in some periods, signals are disrupted up to 60 or 70 percent of the time, posing risks for landings and mid-air collision prevention, particularly during low-visibility conditions.
