Two adjacent jammers will affect each other

GPS jammer or gps jammer describes a device in which the global positioning system (GPS) signal operated by the U.S. Department of Defense will be jammed or completely blocked. Such transmitters make it difficult to correctly receive radio signals (such as radio waves, television, mobile communications or GPS signals). To this end, electromagnetic waves are emitted, which completely or partially superimpose signals and waves from the interfered transmitter, making them unusable. Jammers can work on the same or adjacent frequencies. Therefore, the field strength of the jammer and the type of interference wave are very important.

Interfering with GPS signals requires only a small amount of interference energy to temporarily or completely block GPS signals. Because the transmit power of GPS satellites that orbit the earth's surface for more than 20,000 kilometers is relatively low. Even a small GPS jammer may interfere with the signal within a radius of about 10 meters. This means that GPS trackers can no longer be used for GPS tracking of vehicles. An improvement of GPS interference is the so-called GPS spoofing. In this much more complicated process, the GPS jammer will send the wrong GPS signal, so it will simulate the satellite signal, for example B. Guide the enemy vehicle, ship or plane to go the wrong way.
