The rapid development of the drone market has also driven the development of related industries. As a high-tech product, drones have undoubtedly brought great convenience to people's lives. Many illegal elements can take advantage of this opportunity, they use drones to hinder public safety, and even affect the safety of people's lives and property. The accompanying drone countermeasure equipment ensures the normality of social order.

The UAV anti-jammer device blocks the UAV's uplink flight control channel and satellite positioning channel, so that it loses flight control instructions and satellite positioning information, making it unable to fly normally. Different settings will have the control effect of returning, landing and falling. The 2.4GHz/5.8GHz frequency band signal it emits will cut off the drone's flight control signal and satellite positioning signal. When the GNSS navigation system loses the signal, the flight control system and the signal transmission system are out of control, cutting off the connection between the UAV and the ground end of the remote control, the UAV will be forced to land or return to home automatically.

The drone jammer device suppresses the control signal by transmitting a high-power same-band jamming signal to the UAV, interfering with the sensor, link and positioning system of the target UAV, forcing the UAV to land on its own or Return. After the interference information is sent, the drone and the remote control cannot hear any instructions from the other party at all. At this time, they can only land or return.
