Unique devices commonly referred to as GPS jammers (suppressors or GPS blockers) that have recently appeared in the electronic navigation system industry. The task of these portable gps jammer devices is to prevent any attempts to identify the exact location by using GPS tracking. In this article, we will provide you with the opportunity to review the short gps jammer review. The GPS signal jamming system is designed to suppress the signals of the global satellite navigation GPS system in the 1500-1600MHz range. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. Gps jammers can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius. These are the basic frequency bands. They are all GPS-enabled devices, including trackers that can track all coordinates. After turning on the navigation blocker, all trackers that can use GPS to identify your location stop receiving signals and disappear from the monitor screen.
