GPS-forstyrrelser forstyrrer satellitnavigation omkring Gotland og Öland, Sverige
I begyndelsen af 2025 påvirkede tilbagevendende forstyrrelser af signaler fra det globale satellitnavigationssystem (GNSS) de svenske øer Gotland og Öland i Østersøen. Ifølge Det Polske Institut for Internationale Anliggender (PISM) var forstyrrelserne en del af et ekspanderende mønster af satellitnavigationsforstyrrelser, der i stigende grad havde påvirket svensk territorium siden anden halvdel af 2024. Forstyrrelserne truede pålideligheden af GPS-afhængige navigationssystemer, der bruges af civil luftfart og søtransport i den omkringliggende Østersøregion. Sveriges Transportstyrelse dokumenterede efterfølgende en betydelig stigning i rapporterede GNSS-forstyrrelser i 2025, hvor forstyrrelserne strakte sig fra internationalt farvand ind i svensk luftrum og territorium. Svenske myndigheder identificerede signaler med oprindelse i russisk territorium, særligt Kaliningrad-regionen, som en væsentlig kilde til forstyrrelser. Forsvarsminister Pål Jonson bekræftede, at Sverige overvågede situationen og koordinerede med nabolande, NATO og Den Europæiske Union for at styrke navigationsrobustheden. De tilgængelige kilder identificerer ikke individuelle datoer, specifikke berørte fly eller skibe eller det sendende udstyr, der er ansvarligt for forstyrrelserne omkring de to øer.

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.
