The US government is purchasing about 100 hand-held UAV jammers to protect government facilities, property and personnel.By 2023, the military will once again have its own offensive jammers.As part of the “peace dividend” of the 1990s, the military phased out its electronic warfare forces.2.4 GHz is one of the most commonly used frequencies for controlling UAVs and belongs to ISM band.The high-power jammer operates in the general industrial, scientific and medical (ISM) frequency band.
They are too slow to adapt and only a few meters away.A person who fights in an electronic warfare system “It’s no exaggeration to say that almost all the functions we have can be destroyed“ Interference management training requires GPS jammer training.General Tom Greco, director of Perkins Intelligence Agency, said that although we hope never to fight with Russia or China in the future, we are almost certain that we have purchased Russian advanced jammers and interferometers, and even some of our own allies.
