The Raysun MD1 Multicopter Defender is a shoulder rifle that disrupts a drone’s radio frequency within three seconds, giving its operator the impression that it is out of range. The drone is then programmed to return to its owner, make a controlled descent, or fall out of the sky. The device facilitates control of ISM or GPS signals individually, so the user can cut down an ISM signal while keeping the GPS working to track the owner’s position and respond. There is a night vision device and thermal scope for night-time operation within 1,100m. The system has been used by the Iraqi military.
