Bulgaria’s State Agency for National Security, working with the Communications Regulation Commission and Sofia police, has located and neutralised a powerful GPS jammer in Sofia’s Dragalevtsi district after interference was detected around the capital and near Vasil Levski Sofia Airport. The device had been suppressing GPS frequencies across the city, affecting aircraft navigation systems over Sofia, while airport operations continued normally and flight safety was not compromised.
The jammer was found inside a heavily guarded residential complex during a coordinated operation. Authorities activated standard procedures rather than emergency measures as they traced the source of the signal. Transport Minister Georgi Peev, Sofia Airport and Bulgaria’s air traffic authorities were among the bodies involved in the response.
Officials have not disclosed who owned or operated the device, how long it had been active or its technical specifications. Regional coverage has also linked recent GPS disruptions to takeoffs and landings in Sofia, although it remains unconfirmed whether those incidents were caused by the same jammer.
