Baltic Sea GPS Jamming: Ships Suspected as Culprits
2025-03-05
Polish researchers have linked massive GPS disruptions in the eastern Baltic Sea to ships operating in the region. Between June and December 2024, they detected 84 hours of GNSS interruptions in the Bay of Gdansk, primarily caused by jamming, not spoofing. October saw the peak of activity, with two types of interference identified, suggesting increasingly sophisticated techniques. The study highlights the urgent need for a dedicated GNSS interference monitoring network along the Baltic coast to address these growing threats to maritime navigation and safety.
