Poland is experiencing widespread disruptions to GPS signals over the Baltic Sea and has linked the interference to hostile actions by the Russian Federation, according to Polish defense officials.
Speaking at a press conference on June 17, Polish Minister of National Defense Władysław Kosiniak-Kamysz confirmed that the disruptions have been observed not only by Poland but also by NATO allies in the Baltic and Northern Europe.
“This activity is associated, according to our sources, with the actions of the Russian Federation, including acts of sabotage,” he stated.
The disruptions are affecting both military and civilian operations. The Polish Armed Forces’ Operational Commander, General Maciej Klisz, has issued new recommendations for military aviation, and relevant information has been shared with civil aviation authorities, air traffic control, and the Polish Air Navigation Services Agency.

A special security committee meeting on the issue took place several weeks ago.
Poland’s Internal Affairs Minister Tomasz Siemoniak also confirmed that state security services are monitoring the situation in coordination with national aviation and airspace safety agencies.
According to Siemoniak, the interference is not limited to civil aviation but also impacts military units and strategic infrastructure.
On June 16, Poland’s Air Navigation Services Agency published an official notice warning of significant GPS interference in northern regions of the country. The disruptions have already forced flight rerouting — a passenger aircraft en route from Alicante to Bydgoszcz was diverted to Poznań due to navigational difficulties.

Drone operators have reported loss of control and erratic behavior of unmanned aerial vehicles in the affected areas. Authorities are also investigating possible spoofing incidents, where false GPS data could mislead aircraft or UAVs.
Similar cases have been reported in other NATO countries, including Estonia, Lithuania, Finland, and Sweden.
Earlier, on June 11, Lithuanian Deputy Defense Minister Karolis Aleksa warned that Russia had intensified GPS jamming across the Baltic region, affecting both military and civilian systems. He said the disruptions appeared deliberate and tied to Lithuania’s defense efforts and the broader war in Ukraine.
