UAV jammers can also interrupt GPS signals, which is an important function because self-guided UAVs rely on satellite navigation guidance. Once stuck, the drone can be manipulated in place. The Ministry of Defense will not disclose whether the interference caused the drone to crash for safety reasons. Pentagon spokesperson Eric Pahun said: "The U.S. military maintains adequate countermeasures and protective measures to ensure the safety of our manned and unmanned aircraft, our troops and the missions they support. Drone interference The device is a way for security professionals and law enforcement agencies to prevent drones from destroying our security and privacy. Officials said that the equipment used was developed by the Russian army and is a very advanced device that has been proven to be effective against certain encrypted signals and Anti-GPS jamming receivers are also effective. So far, drones are small reconnaissance aircraft, unlike large "Predators" and "Reapers", they usually operate in combat environments and can be armed.
According to the Iraqi general, the on-board "signal launch" signal provided by the United States to the Iraqi security forces greatly reduced the threat of ISIS drones in the battle for Mosul. Others will return to the reverse mode, such as going home or moving to the ground. The advantage is that the drone falling from the sky will not cause collateral damage. Moreover, the Drone jammer will not damage the drone itself. If drones belong to an innocent party, so much the better. Jammer-shop’s radar jamming gun forces the drone to immediately land or return to the drone operator, which means it can protect personnel and infrastructure assets from drone attacks. A distinctly different type of anti-riot weapon found in Iraq is the DroneDefender made by Battelle, which is similar to an assault rifle but has a directional Power frequency blocker mounted on the frame. It has a range of about 400 yards and can work by interrupting the link with the drone controller or GPS device.
The rifle jammer can simultaneously turn off the signals in the 433MHz, 915MHz, 2.4GHz and 5.8GHz RF bands to ensure that it covers all the most common signal frequencies used by drones for communication, and can choose to create GNSS interrupts (basically, GPS and GLONASS will not work). After turning off the signal, any nearby drone will be forced to land or return to its starting point, depending on how its internal algorithm is configured, allowing people to retrieve it for investigation (if land) or return to potential threats (if you Return home). When it gets stuck, the video stream of the drone will also be interrupted immediately, so you can no longer stream any material to the operator.
