GNSS interference in the Baltic Sea region traced to mobile emitters offshore Kaliningrad.
During October 2024, satellite-based monitoring showed a significant spike in GNSS (Global Navigation Satellite System) interference over the Baltic Sea, with aircraft transiting north-west of Kaliningrad experiencing total positional signal collapse for extended periods. This maritime zone is adjacent to Sweden’s eastern approaches and the Baltic Sea air-space corridor, making navigation and surveillance operations vulnerable to jamming from vessels or fixed emitters in or near Russian operational zones. Data analysis from Spire suggests that the interference pattern is consistent with a moving emitter (likely ship borne) rather than a fixed ground site — indicated by rapid localization and fall-off of signal disruption in adjacent areas. This incident underscores that Sweden (and the broader Baltic region) faces hybrid-warfare pressure not only from surface or air incursions but also from the electronic domain, where navigation and surveillance systems are degraded or masked. The event triggered increased monitoring of GNSS interference by Baltic states, enhanced maritime-domain awareness, and new procedures for aircraft and vessels transiting the Baltic Sea under degraded GNSS conditions.
