Sweden’s Transport Agency said on Thursday that from January through August 2025 it received 733 reports of Global Navigation Satellite System (GNSS) interference, such as with GPS. That compares with 495 reports in all of 2024 and 55 in 2023.
“The disruptions have intensified, occurring over a wider area, both over the Baltic Sea and over Sweden’s land territory,” said Andreas Holmgren of the agency. He called the trend “serious,” warning it “poses a threat to civil aviation, especially given the scale, duration and character” of the incidents.
Pilots can switch to other positioning methods, he noted. The problem also affects maritime navigation and the positioning of sensors tied to critical infrastructure.
The agency added that the figures likely understate the scope of interference because some foreign airlines report incidents only to authorities in their own countries.
In July, the Council of the International Civil Aviation Organization, after reviewing evidence submitted by the Baltic states as well as Finland, Sweden and Poland, urged Russia to cease GNSS signal interference that has frequently forced aircraft, ships and drones in the Baltic Sea region to alter their routes.
