Anti-drone technology in China and the United States

The US military has been evaluating various anti-UAV measures for several years, consisting primarily of signal blocking or blocking, and radar detection and conventional counterattack that are commonly used against aircraft.

“If you’re just static on one part of the spectrum, of course they’re going to attack you and get stuck,” said Marine Corps Col. Jeffery Kawada, deputy director of the Information Warfare Integration Division at headquarters. Marine Corps Capacity Development Command, he said. “But if you can maneuver the spectrum and you can feel that and you can maneuver into a clean part of the spectrum, that’s the intent of everything we’re doing … to be able to do dynamic spectrum access … we know we’re going to get stuck. because we are doing it to them. ”

A quick Google search will find several companies claiming to sell devices that can block drone control signals, which can cause an unwanted quadcopter to crash or return to its point of origin depending on the manufacturer.

Do you have a drone and want to have fun with it? The technology uses an emission of wifi interference that will interrupt the connection between the drone and the controller. It can be quite effective in taking down drones that use Wi-Fi as their communication method.

China, October 29, 2017 – Unmanned aerial vehicles (UAVs) or drones could generate various types of threats and be interfering with one’s privacy. This is the reason why many people often look for effective drone interference solutions to lead a peaceful and safe life. China-based Perfectjammer Technology Company has innovative interference for UAVs and wireless communications that can protect people from these aerial devices. Recently, they have developed long-distance¬†drone jammer¬†that can be used to hit a device from a significant distance of up to 1000 meters.

According to a spokesperson for Greatjammer Technology Co., Limited, long-distance jamming uses radio control frequency disruption technologies to stop drones in the air to help establish the security of military installations or civil colonies. The weapon operates on the standard GPS and ISM radio bands, 2.4Ghz to 5.8Ghz Wi-Fi allowing it to interfere with commercial UAV signals. The gun can operate with a significant frequency range, making it possible to detect and shoot down a UAV from a far distance.
