The application of vehicle-mounted jammers in border defense and the army The vehicle-mounted jammers protect the army and the VIP motorcade from the attacks of remote-controlled improvised explosive devices (RCIEDs) that were buried in advance by terrorists, and can effectively prevent terrorists from tracking the motorcade through GPS. Prevent terrorists from being attacked by remote improvised explosive devices buried along the way during border defense and military patrols. The GPS signal jamming system is designed to suppress the signals of the global satellite navigation GPS system in the range of 1500-1600MHz.
It is used by the police to interfere with the common communication frequency in the process of rounding up criminals, so as to prevent criminal gangs or the police from leaking secrets through wireless devices, making the patrol ineffective. The range of the GPS jammers can be from 5 to 15 meters, which is sufficient for cars, trucks and buses because the tracker is usually installed in the cab inside the car.
At the same time, illegal elements hidden in the military protection zone cannot communicate with the outside world wirelessly and leak secrets. It is used in military protection areas, government buildings and other important places to shield wireless signals, which can effectively prevent terrorists from conducting targeted blasting through remote control bombs.
The jammer makes it impossible for GPS satellites to monitor the position of cars and all vehicles through GPS. GPS jammer devices will not interfere with mobile phones and other devices. At the same time, it can also prevent criminals from remotely controlling bombs at the key entrance of the building, so that the police can quickly enter the building to round up and avoid casualties.
After the connection is started through the vehicle cigarette lighter, the equipment starts to work immediately and generates radio noise (interference) within the range of 1500-1600 MHz (L1/L2) within a radius of 15 meters. Before explosive removal, it is necessary to effectively shield the wireless communication signals around the bomb to prevent terrorists from detonating the bomb through remote control wireless devices during explosive removal, so as to avoid causing huge casualties.
