GPS jamming disrupts satellite navigation around Gotland and Öland, Sweden.
During early 2025, recurring interference with Global Navigation Satellite System (GNSS) signals affected the Swedish islands of Gotland and Öland in the Baltic Sea. According to the Polish Institute of International Affairs (PISM), the disruptions formed part of an expanding pattern of satellite navigation interference that had increasingly affected Swedish territory since the second half of 2024. The interference threatened the reliability of GPS-dependent navigation systems used by civilian aviation and maritime transportation in the surrounding Baltic Sea region. Sweden’s Transport Agency subsequently documented a substantial increase in reported GNSS disturbances during 2025, with disruptions extending from international waters into Swedish airspace and territory. Swedish authorities identified signals originating from Russian territory, particularly the Kaliningrad region, as a major source of interference. Defence Minister Pål Jonson confirmed that Sweden was monitoring the situation and coordinating with neighbouring countries, NATO and the European Union to strengthen navigation resilience. The available sources do not identify individual dates, specific affected aircraft or vessels, or the transmitting equipment responsible for the disruptions around the two islands.
