Several NATO members accuse Moscow of deliberately jamming positioning signals

GPS is no longer reliable around the Baltic Sea and northern Norway. Interference in the Global Positioning System (GPS), which has affected all NATO members bordering Russia for two years, has worsened in recent months. Alternative systems to GPS have had to be activated on tens of thousands of flights and the main Finnish airline has suspended one of its routes due to the problem, which is also disrupting maritime navigation. Several of the affected countries accuse Moscow of intentionally jamming signals with its electronic warfare systems.

Since the Russian invasion of Ukraine in February 2022, GPS interference has been recurring in Estonia, Latvia and Lithuania. These types of disruptions are common in and around conflict zones. Even so, in the last half year, the airspace of the three Baltic countries — in addition to that of Finland, Sweden and Poland — has been much more affected than at the beginning of the war. What’s more, thousands of ships have been navigating the Baltic without GPS since December, when the Russian army’s electronic warfare began in the Kaliningrad enclave. And in remote northeastern Norway, near Russia’s Northern Fleet base — which has eight of the 11 Russian submarines capable of launching long-range nuclear missiles — outages are almost daily.
