Russia has intensified GPS signal disruptions over Estonian airspace since mid-2022, expanding their reach in 2024, aiming to hinder attack drones, though commercial flights are unaffected.
GPS disruptions in Estonia have notably increased since Russia’s full-scale invasion of Ukraine in 2022, with interference signals originating from Leningrad Oblast, Russia. Estonian Air Navigation Services CEO Ivar Värk stated pilots report 10-20 daily GPS disruption cases in certain airspace areas, with disruptions expanding in early 2024 beyond northeastern Estonia to include the Gulf of Finland and central regions. An alternative navigation system has been in place since March 2024, ensuring commercial aircraft operations remain stable and no flight cancellations have occurred. The purpose of these disruptions appears to be Russian efforts to degrade the operation of attack drones threatening its territory, particularly in the south. The Estonian Consumer Protection and Technical Regulatory Authority monitors these signals and confirms ongoing disruptions. Monitoring is supported by the gpsjamorg website.
Confidence: High
The post clearly identifies Russian-origin GPS signal jamming targeting Estonian airspace as hostile aggression aimed at disrupting drone operations. Simultaneously, Estonia has developed and activated a backup navigation network in response, demonstrating defensive preparations. The high confidence is due to direct quotes from official Estonian sources and precise incident details.
