[Battelle], an Ohio-based non-profit R&D firm has just unveiled a device they call the DroneDefender — a long-range anti-drone defense weapon. It almost sounds like they’ve brought the fictional drone hunter’s RF cannon to life. But does it really work?

According to the site, it uses radio frequency disruption to blast unwanted drones out of the sky. Cool concept, but does it actually work? Unlike the hackable MAVLink protocol used by Parrot AR, ArduPilot and a handful of other consumer drones, this weapon uses brute radio signal force to disable any(?) consumer drone.

There’s a video after the break demonstrating a simulated use of the technology, which leaves us a bit confused. They show the drone slowly landing all nicely after being “guided” down by the rifle. If the system is jamming both GPS and the 2.4 GHz control link, the behavior will all depend on the software loaded on the drone. Some will go to a fail-safe mode, which is low throttle or motor power off, assuming the pilot has set fail-safe. Others may attempt to loiter on IMU sensors only.
