Drones are unmanned aerial vehicles or unmanned aircraft systems that is essentially known as flying robots. Drones are remotely controlled or flies autonomously through software controlled flight plans in their embedded systems working in conjunction with on-board GPS and sensors. In recent days, drones are most widely used in military and army forces, where they are used for anti-aircraft target practise, intelligence gathering, and then more controversially, as weapons platforms. Side range of civilian roles ranging from search and rescue, traffic monitoring, weather monitoring, surveillance, etc. can be done with drones.
In army forces and defences drones are most widely used for gathering ground information of enemy activities. But, the question now is how to shoot a drone out of sky? Just read on the article to know how to shoot a drone out of the sky.
The big-iron drone hunters:
Anti-drone idea has been started by military few years ago. Military contractors like Boeing, Raytheon, Lockheed Martin, Thales group, Israel Aerospace industries and Russia’s United Instrument Manufacturing Corporation, etc. have developed powerful anti-drone technologies.
U.S Army is testing Raytheon’s Phaser, which is an electromagnetic pulse device that can shutdown entire drown swarm with a single blast. But, the trouble is, big-iron solutions are right for airplane sized drones used by major military powers. But, terrorists, criminals, and insurgents are increasingly flying smaller, consumer sized drones for delivering bombs. These smaller drones very badly needs a smaller solution.
U.S Marine Corps are working on truck-mounted laser beam, which kills smaller drones in flight. And the U.S. Air Force want handheld drone killing kits. The need for non-military, domestic, anti-drone tech is increasing even though military contractors develop new tech to defeat large and small drones. Even Airports, ports, power stations, and special events are driving an explosion in anti-drone technologies.
There are different approaches and technologies that are widely involved in fast growing anti-drone industry. “Space gun” approach that uses special purpose rifles designed to shoot a focused ray that jams all the frequencies that consumer drones use to communicate with their handheld controllers. The latest anti-drone “space gun” is DroneShield’s DroneGun, which is demonstrated on video for the first time this week. Another one is Battelle’s DroneDefender. Both these works by jamming all the radio signals that drone can use to interact with a handheld controller. Hence, they make the drone react as if the controller is in offline.
The “Signal jamming” approach is the other one, which is most commonly used and many products are ground based rather than shoulder-fired. The companies that make 360 degree, multi-drone signal disrupter include Elbit systems, Blighter Surveillance systems, Selex, SRC, Dedrone, and Liteye Systems.
The other way to stop a drone is by throwing a net over the drone in order to bring it down. These could be shoulder-fired nets, which can bring down a drone from up to 100 yards away. This approach uses a computer controlled targeting system, which shows distance and displays green light when your aim is correct.
Another approach is to hack the drones. A company named Department 13, which is funded by a Pentagon’s Defense Advanced Research Projects Agency, hacks drones by injecting packets of code in to the radio protocol that is used for communication purpose between the drone and its handheld controller. When a product named Mesmer successfully cracks radio protocol, it will take the command of the drone.
