In mid-January 2019, one of the GGS crews searching for a stolen Audi Q7 noticed a continuous GSM jammer signal operating in several bands in the Nowy Dwór Gdański region. The signal was so strong that it allowed the crew to easily determine the place from which it was emitted. Despite the jamming, a signal was also sent by the GanTrack module installed in the vehicle, which only assured experts from Gannet Guard Systems that the stolen Audi was parked in a “chop shop”. All information and coordinates of the place were forwarded to police officers. The vehicle was successfully recovered.
