 Russia's GPS jamming testing NATO ahead of potential war. Russia is disrupting satellite systems in the Baltic region in preparation for conflict with NATO. An Estonian military commander has said, as the head of a GPS security group called for the Alliance to act to protect the system used by airlines, smartphones and weapons systems. This is according to Newsweek. The publication says that in January, jamming was detected in eastern and southeastern parts of NATO's newest member Finland amid reports from an open-source intelligence researcher that a Baltic jammer in Kaliningrad, Russia's Baltic Sea enclave, was responsible. The Russian Defence Ministry has previously confirmed its electronic warfare units in Kaliningrad, which borders NATO members Poland and Lithuania, had conducted exercises to disrupt radio and satellite signals. On various days throughout January, GPS disruptions have been recorded in northern Poland, southern Sweden, Estonia and Latvia. So far there is no proof Moscow was involved in the disruptions in January, but Russia has been accused of jamming GPS signals in northern Europe and its electronic warfare capabilities are used to disrupt drones and missiles in Ukraine during its full-scale invasion. Martin Haerem, commander of the Estonian Defence Forces, told Bloomberg, Someone is causing it and we think it's Russia, and that Moscow is learning and testing jamming capabilities ahead of risks of a future potential conflict with NATO. He said that Moscow had shown its electronic warfare capabilities elsewhere, not just in Ukraine and the Baltic countries, adding that Russia is definitely quite strong in this. Dana Gawad, President of the Resilient Navigation and Timing Foundation, which advocates for GPS security, wrote in an op-ed for breaking defence, Such jamming presents a risk to thousands of commercial aircraft. As international pressure has so far failed to halt the interference, it's time for NATO to act proportionally, he added.
