Drone jammer is used to conduct electromagnetic interference on the UAV GPS receiver, so that the UAV can only rely on the inertial guidance of the gyroscope, and cannot obtain accurate positioning information. Relying on cameras and the information they get is meaningless without accurate map connectivity. Today's aircraft are, at best, flying cameras. It's a colossal waste, both on and off the military map.

Some drones need to be guided by communication signals. Once there is no signal guidance, it is impossible for them to sail freely in space and be controlled wirelessly in a short period of time. But such an operation also means that they can only conduct strategic reconnaissance on the battlefield and cannot play a big role. The drone signal jammer countermeasure system can be widely used in key areas such as key military regions, party and government agencies, and prisons, and can achieve 24-day and night-time uninterrupted protection. The UAV jammer countermeasure system interferes with the remote control chain of the "Black Fly" unmanned reconnaissance aircraft by means of jamming signals; uses false guidance signals to interfere with the guidance components of the "Black Fly" unmanned reconnaissance aircraft; the remote control signal of the "flying" UAV Can be reversed; on licensed drones, the launch zone can be used to boost their navigation signal. Its advantages are: fewer decoy signals are emitted, and the coverage after installation is controlled within a certain range.
