Battelle’s DroneDefender™ is the first portable, accurate, rapid use counterweapon to stop suspicious or hostile drones in flight, providing critical security protection at home and abroad. The Battelle DroneDefender uses radio control frequency disruption technologies to safely stop drones in the air before they can pose a threat to military or civilian safety. The growing use and availability of commercially available drones – also known as Unmanned Aircraft Systems (UAS) – is raising concerns among defense, security and law enforcement leaders. DroneDefender is an inexpensive, easy to use, lightweight, point and shoot system with a demonstrated range of 400 meters. DroneDefender provides instant threat mitigation, quickly disrupting the drone so that no remote action, including detonation, can occur in sensitive areas. This minimizes drone damage and the risk to public safety. This device has a cold start time of <0.1 seconds and an operating time of five continuous hours. It weighs less than ten pounds, depending on how it is configured. The research team which developed the DroneDefender drew from their own extensive military backgrounds, as well as Battelle’s deep technology expertise and its 70 year history addressing complex Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) defense challenges. Because it is designed to repel undesirable UAS attention without doing damage to the UAS, DroneDefender can be used stateside as well as abroad, with versions hardened for forward deployment in challenging environmental conditions. It can be either fixed or portable, with battery packs available to help protect any installation, mobile VIP or unit. To view a brief video of how it works, go to https://youtu.be/zx4XXLb_Vuw.
