Estonia: GPS jamming traced back to Russia’s Leningrad region

GPS systems in the Baltic Sea region, including Estonia, experienced disruptions attributed to Russia at the end of 2023, according to monitoring websites, ERR reports. Estonia witnessed major disruptions along its eastern border and in the south. The disruptions were traced back to Russia’s Leningrad region, with potential spillover into Estonian and neighbouring airspace, according to Estonia’s Consumer Protection and Technical Regulatory Authority (TTJA). Despite the disturbances, aviation and other global satellite navigation systems on the ground remained largely unaffected. Experts suggested a possible Russian hybrid attack, while noting that the disruptions did not pose a significant threat to air traffic.
