Russia has created a new electronic warfare system, Multik, to detect and disrupt FPV drone signals, aiming to protect its helicopters from drone attacks.
The Multik system, developed by the Gradient Research Institute, is designed to be mounted on helicopters and other vehicles. It has undergone airborne trials and exists in hardware form.
The system seeks and jams the video-transmission frequencies FPV pilots use to steer and observe small attack drones.
