Rising GPS Jamming Threats in the Baltic Sea: Accusations Against Russia

Overview of GPS Disruptions
In recent months, a significant increase in GPS signal disruptions over the Baltic Sea has raised safety concerns for civil aviation. The Swedish Transport Agency reported that incidents of interference with global navigation satellite systems (GNSS), including GPS, surged from 55 in 2023 to 733 by September 2025. This interference, which includes both jamming and spoofing, has spread from Sweden’s eastern airspace to broader areas affecting both land and sea.
Accusations Against Russia
Sweden and several Baltic nations, including Estonia, Finland, Latvia, Lithuania, and Poland, have accused Russia of being the source of these disruptions. The Swedish authorities traced the interference to Russian territory, particularly from the enclave of Kaliningrad. Andreas Holmgren, head of aviation at the Swedish Transport Agency, emphasized the seriousness of the situation, stating, “This is serious and is a security risk for civil aviation.” The International Civil Aviation Organization (ICAO) has expressed grave concern and urged Russia to cease these activities.
Impact on Aviation and Maritime Operations
The disruptions have had tangible effects on aviation safety. Reports indicate that nearly 123,000 flights were affected by Russian jamming and spoofing between January and April 2025. Pilots have had to rely on alternative navigation methods, including paper maps, during critical moments, as evidenced by an incident involving European Commission President Ursula von der Leyen's flight, which experienced GPS interference while landing in Bulgaria. The Bulgarian Prime Minister attributed the interference to Russian electronic warfare systems, further complicating the geopolitical landscape.
Official Responses and Criticism
While European officials have pointed fingers at Russia, the Kremlin has denied these allegations. Dmitry Peskov, a Kremlin spokesperson, labeled the claims as incorrect, and Bulgarian officials have downplayed the significance of the reported GPS disruptions, asserting that such incidents are common and do not warrant investigation. Bulgarian President Rumen Radev dismissed the allegations as an "invented scandal," emphasizing that the aircraft's navigation systems have multiple backups to ensure safety.
Conflicting Reports and Gaps
Despite the accusations and rising incidents, there remains a lack of definitive evidence linking Russia directly to the GPS jamming. The UK's Civil Aviation Authority noted that while GPS jamming is a concern, aircraft are equipped with alternative navigation systems that mitigate risks. However, the frequency and geographical spread of the disruptions have alarmed regional authorities, prompting discussions for coordinated action among EU member states.
What's Next
As the situation evolves, Sweden and its Baltic neighbors plan to escalate their concerns at the upcoming ICAO general assembly. The European Commission is also preparing to address the threats posed by GPS jamming in a statement to the European Parliament, highlighting the need for a unified response to safeguard aviation and maritime navigation in the region.
