Jamming: Polish researchers suspect GPS jammers on ships in the Baltic Sea

Ships sailing in the eastern Baltic Sea are at least partly responsible for the massive disruptions to satellite navigation systems such as GPS in the region that have been complained about since the end of 2023 at the latest. This is the result of a new study by Polish researchers. The scientists observed GPS interruptions at ground level between June and December 2024 using a sensor they had installed at the Gdynia University of the Sea in northern Poland. The university is located around 35 kilometers from Gdansk and 120 kilometers from the Russian Kaliningrad Oblast (Königsberg). In total, they detected disruptions to global navigation satellite systems (GNSS) over a period of 84 hours. These had caused persistent problems in the area for ships to stay on course. Anzeige In the analysis, which was limited to the Bay of Gdansk, the experts identified jamming, in which the radio signal from the satellites is disrupted, as the main cause. Spoofing did not play a major role. This inv ... Read full article.
