An app for detecting potentially hostile drones has been developed for the U.S. Army.

The CARPE Dronvm is an app that can be used to identify drones as well as alert authorities of their location. Task Force 39, an arm of the U.S. Army designed to counter the threat of hostile drones to soldiers serving in the Middle East where they have come under repeated drone attacks, recently tested the app.

The app — which was developed by the MITRE Corporation with funding from the U.S. Department of Defense (DoD) — enables users to capture photographs of unfamiliar drones. Once captured, the images can be sent to a so-called “processing engine” to determine if a drone is pictured and where it is located by geolocating it on a situational awareness map at the command center. Once located, nearby CARPE Dronvm users are sent an alert about the drone.

According to its developers, CARPE Dronvm relies on the global network of smartphones currently in existence — of which there is an estimated 5.2 billion worldwide — and that feature both cameras and internet connectivity, turning every smartphone into a networked sensor and, subsequently, a potential drone detector.

CARPE Dronvm will soon be available for iOS and Android operating systems.
