Speaking during a visit to the construction site of the Baltic Power offshore wind farm near the seaside resort town of Łeba, Tusk warned that such disruptions—which he said are believed to be caused by Russia—could have serious consequences for critical infrastructure projects.
"This interference, most likely originating from the Kaliningrad region, is disrupting air traffic, including passenger flights, and now also threatens the precision of strategic investment projects," Tusk said.
The Baltic Power project, a joint venture between Polish energy giant Orlen and Canada's Northland Power, is set to become the largest offshore wind farm in Poland’s section of the Baltic Sea.
Tusk told reporters that GPS signal jamming has been reported by pilots from Poland, Sweden, Estonia and Lithuania since Russia’s full-scale invasion of Ukraine.
Similar interference has also been observed by ship crews in the Gulf of Finland, Polish state news agency PAP reported.
"Even this project has experienced GPS jamming, which can seriously impact the construction process," he said, referring to the wind farm under construction.
He added that "precision is essential" for such offshore operations.
Poland currently holds the rotating presidency of the Council of the Baltic Sea States.
Tusk said the upcoming summit would focus on regional cooperation and safeguarding critical infrastructure, especially in the face of emerging "hybrid threats."
He also told a news conference that Poland was coordinating with both NATO and Baltic partners, bilaterally and multilaterally, to strengthen maritime security.
In July, the International Civil Aviation Organization (ICAO) called on Russia to cease GPS interference in the region after reviewing evidence submitted by Poland, Finland, Sweden, and the Baltic states, the PAP news agency reported.
The disruptions have forced aircraft, ships and drones to alter their routes, it said.
