What is a drone jammer and how to deal with it?

Drone jammer is some means that can control and interfere with the normal flight of UAVs, that is, to interfere with the UAVs in flight through some technologies and make them 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.

After a series of operations, during the flight of the drone, 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. The signal generator is used to generate electromagnetic signals that interfere with the communication of the drone, and the drone can directionally interfere so that it cannot acquire the signal. Accurate enough coordinate data to achieve the purpose of UAV confrontation.
