New Russian signal-jammer near Narva escalates GPS interference on Estonia’s eastern border.
Estonia’s Consumer Protection and Technical Regulatory Authority (TTJA) issued a notice that a newly-deployed Russian electronic-warfare jammer positioned near the border had escalated interference with GPS/GNSS signals in the Narva area — the disruption extended to drones, ships and potentially smaller general-aviation flights. Narva lies at a critical threshold zone between NATO-member Estonia and Russia, with combined land, sea and air corridors that are sensitive to navigation disruption and maritime/air defence monitoring. The dynamics of the incident reflect hybrid-warfare logic: by degrading satellite-navigation integrity near Estonia’s border, the actor forces increased allocation of domestic surveillance assets, unmanned-systems operators must re-route or cancel missions (TTJA advised against drone flights in the area), and the ambiguity of attribution (Russia denies but is strongly suspected) creates uncertainty without triggering open combat. Tallinn’s authorities noted this fits a pattern of Russian jamming operations across the Baltic since 2023, including in Kaliningrad and St Petersburg sectors, thereby expanding the maritime-air-navigation front of hybrid operations. The incident prompted Estonia and 12 other EU countries to call on the European Commission to respond to GNSS interference as a strategic security threat.
