Jammers can eliminate the hazards of drones

Drones are everywhere, and some are dangerous. Now, the authorities can protect us from any threats. UAVs are small remote-controlled fixed-wing or helicopter aircraft. UAVs were previously limited to military applications and have entered the civilian market. They are mainly used as camera platforms, but are also increasingly used for delivery purposes. The boom in the civilian drone market has brought security and data protection issues. The same drone that delivers pizza or packages may also carry payloads for terrorist purposes.

This danger is very real. In 2015 alone, there were more than 30 cases where drones were used to smuggle contraband into British prisons. In 2016, Daesh used high-quality consumer drones to monitor and drop bombs. Many other security breaches and incidents have occurred, especially at airports. Security personnel need a way to eliminate the threat of drones while allowing legally approved use. This will make possible the KNOX project funded by the European Union. The project team optimized its technology, demonstrated in actual operation, and prepared a system to commercialize it.

drone jammer, KNOX will detect drones on approach. It is usually pole-mounted equipment installed around safety facilities. Due to its flexibility and scalability, it can also be used in other types of configurations, such as B. Mounting on the boundary wall. It consists of a radio detector (called a watchdog), a radio interference transmitter (Doberman), a radar system (Eagle) and a control system (Iris/Argos). The watchdog is around the building and the eagle is in the middle of the network.

The watchdogs each rotate 60 degrees and look for signals between the controller and the drone. The eagle scans 360 degrees to identify the propeller and follow the trajectory. If the drone gets too close, the Doberman will interfere with the radio control frequency.

Nanna Tribler, the project coordinator of the MyDefence Coordination Company, said: “In most countries, it is illegal to hit Ja unless you are in the police or the military.” Even then, obtaining permission can be difficult. Although the team knew about the Danish licensing restrictions before starting the project, the search was still subject to certain restrictions. However, researchers have obtained special permits to conduct experiments on Danish military bases, while in Finland and Israel, where interference research is less controlled, they have obtained less restrictive permits.

A successful attempt. Despite the obstacles encountered, the KNOX team has successfully tested the system in more than 200 actual situations, including in prisons and other locations such as police stations, stadiums, city centers and military facilities. . The system is also installed on military vehicles. The test successfully prevented unauthorized drones from entering the safe room. Tribler said: “Our interference method is currently the most compact method on the market and has proven to be very effective with minimal collateral damage.” The researchers developed a series of operating procedures based on these tests.

The study also identified the need to report and control all drone air traffic, as well as stricter regulations. Researchers will cooperate with relevant EU authorities to take such measures. After successfully completing the trial, project members plan to apply for funding in the third phase of the EU SME Tool Initiative. At the same time, system development continues. The market research of this project has uncovered potential new opportunities for the European defense industry. In the end, KNOX was launched as the most advanced commercial anti-drone system. Availability on the market allows security agencies to access options that did not exist before to eliminate threatening drones. This will bring greater security to Europeans.
