At present, combining GPS and inertial navigation technology, the drone is equipped with a GPS receiver so that the drone must know its specific position during the shooting process. Once the GPS receiver on the drone is subjected to the electromagnetic interference of the drone, the drone can only rely on the inertial guidance of the gyro, and it is impossible to obtain accurate positioning information. Without the transmission of accurate GPS data, the information obtained by relying on photography would be meaningless, and the current aircraft can only be regarded as a flying camera at best. UAVs need to be guided by communication signals. Once there is no signal guidance, it is impossible for them to navigate freely in the sky, which also means that they cannot play much role in the field.
UAV electromagnetic jammer technology can be widely used in key military areas, administrative offices, prisons and other key areas, and can achieve 24 day and night uninterrupted protection. This technical method is mainly aimed at jamming the signal, which interferes with the remote control circuit of the UAV of unknown origin, and uses the guidance signal to interfere with the guidance element of the "Black Flying" UAV and restrain the "Black Flying" UAV. remote control signal for reverse orientation. The coverage after using UAV electromagnetic uav jammer technology is controlled within a certain range, and on licensed UAVs, the launch area can be used to enhance its navigation signal.
