What is a drone Jammer and How do Fight Drones?

The drone jammer is a means of controlling some interference with the normal flight of the drone, that is, by interfering with the flying drone through some technologies, causing it to fall. How to conduct drone confrontation, first understand the principle of drone flight before that.

During the flight of the drone, the ground operator must issue remote control commands to control it to make various actions. These are all done through remote control technology, which consists of a controller, a control circuit, a data transmission circuit, and a signal receiver. The controller is responsible for the generation of the remote control coded signal and the generation of the ranging reference signal. The control circuit accepts and judges the instruction code output by the controller. The data transmission circuit is mainly responsible for the frequency modulation and high-frequency power of the command signal and sends the encoded signal to the UAV through the transmitting antenna. The signal receiver receives the ground RF signal through the receiving antenna.

During the flight of the UAV, GPS is installed to obtain its own position in real-time, and the GPS satellite navigation system is used for flight control. From the perspective of the GPS positioning principle, GPS signal jamming technology will affect the GPS signal reception of drones. Drone uav jammers are used to generate electromagnetic signals that interfere with UAV communication, and the directional interference to UAVs makes it impossible to obtain sufficiently accurate coordinate data to achieve the purpose of UAV confrontation.
