The Baltic states are experiencing a sharp increase in radio and satellite interference, which officials link to Russia’s growing use of electronic warfare equipment near their borders.
Rising Interference in the Baltic States
Since the conflict in Ukraine began in 2022, disruptions in the Baltic Sea region have become more frequent. These include jamming of the Global Positioning System (GPS), a crucial tool for both civilian and military navigation.
In recent months, the problem has worsened significantly. In Estonia, regulators report that 85% of flights experience disruptions in their navigation systems. Alongside jamming, there has also been a rise in a method called “spoofing,” where false location signals are sent to mislead receivers. Lithuania reported that such incidents increased more than 20 times compared to the previous year, highlighting the scale of the escalation.
The growing disruption affects not just aviation but also maritime and ground-based systems. Authorities warn that the interference poses risks to everyday communication, transportation, and even personal devices like mobile phones and drones across the Baltic states.

Baltic States Raise Complaints to International Agencies
The Baltic states, along with neighboring Finland, Poland, and Sweden, have taken their concerns to international organizations. In June, they filed a formal complaint to the International Telecommunications Union (ITU), pointing out the rise in harmful interference. The ITU, a United Nations agency responsible for managing global communication standards, directed Russia to stop the disruptions immediately.
In early July, the same group of countries submitted data to the International Civil Aviation Organization (ICAO), another UN agency. Based on the evidence, ICAO concluded that Russia was the source of the interference. The aviation watchdog expressed “grave concern” about flight safety and warned that continued disruptions could violate international law.

Despite these warnings, the disturbances have not stopped. Reports suggest that Russian officials did not deny the jamming but argued that the actions were necessary to protect their national infrastructure.
Communication authorities identified four new jamming installations in the Russian exclave of Kaliningrad, a heavily militarized area surrounded by NATO states. At the same time, Estonia and Latvia reported that devices in mainland Russia near their borders caused interference. Officials also believe that Russia installed some of the equipment on naval vessels operating in the Baltic Sea, directly impacting the Baltic states.
Impact on Baltic States’ Transport and Communication
The growing interference has forced pilots, air traffic controllers, and maritime authorities to rely on backup systems. Pilots flying over the Baltic states often switch from GPS to radar-based navigation, which increases the workload of air traffic control staff. Poland’s aviation authority confirmed that disruptions particularly affect the northeastern part of the country, near the Lithuanian border. This area includes the Suwalki Gap, a narrow land corridor between Belarus and Kaliningrad that many consider strategically important.
The disruption affects not only aviation but also other sectors. Ships navigating the Baltic Sea also face problems with spoofed coordinates, raising risks for maritime transport. On land, interference has spread to mobile communication towers, affecting basic services that rely on stable signals within the Baltic states.
Civilians have been warned not to fly drones near the Russian border areas. Officials highlight that spoofed GPS signals can cause drones to fall from the sky unpredictably, posing a risk to people and property on the ground. Estonian authorities estimate that the disruptions have cost their government around half a million euros in damages and mitigation measures.

To counter the problem, the European Galileo satellite navigation system recently introduced new features to make its signals more resistant to spoofing. This move was described as a response to the growing challenges faced in sensitive areas such as the Baltic Sea region.
Despite these efforts, the electronic warfare activities have continued to expand, stretching from air and sea routes to everyday communication systems inland. The situation underscores the seriousness of signal interference and its impact on both civilian safety and regional stability in the Baltic states.
