Russian Satellites Are Jamming GPS Signals Across Europe, Warn Scientists

European airspace is currently under an unprecedented assault, with scientists pinpointing Russian satellites as the source of widespread, deliberate GPS signal jamming across the continent. A groundbreaking research paper, published this week by the University of Texas at Austin, directly attributes the interference, which degrades critical L1 GNSS signals, to Russia's EKS early warning system satellites, including 'Cosmos 2546'. This revelation escalates an already urgent situation, underscoring the growing weaponization of space and the profound vulnerability of the satellite-based systems underpinning everything from commercial aviation to emergency services. These satellite-borne disruptions complement a sharp increase in ground-based GPS spoofing emanating from Russia's Kaliningrad exclave, now boasting 36 antennas capable of affecting a 450 km radius across the Baltic states, Poland, Finland, and Sweden. The intensified electronic warfare campaign, which NATO Secretary-General Mark Rutte has labeled a 'hybrid threat', gained critical attention in September 2025 when a jet carrying European Commission President Ursula von der Leyen experienced mid-flight GPS jamming over Bulgaria, forcing pilots to rely on traditional navigation. European officials have documented thousands of such incidents since Russia's 2022 invasion of Ukraine, with a Ukrainian naval drone recently losing control due to Russian EW and exploding in a Romanian port on June 5, 2026. As the EU races to bolster the resilience of its Galileo system with new authentication services and a 2026 interference monitoring service, the immediate next steps involve navigating this treacherous new normal. NATO has warned that any civilian casualties resulting from such interference would constitute a 'deliberate escalation,' hinting at potential military responses against Russian electronic warfare installations. This relentless, multi-pronged attack on Position, Navigation, and Timing (PNT) services demands a coordinated, robust defense, forcing Europe to re-evaluate its reliance on satellite navigation and urgently develop hardened alternatives.
