Drone jammers mainly use electromagnetic interference (EMI) technology to block or interfere with the control signals of drones. These devices emit radio waves that are close to or the same as the control frequency band of drones, forming "noise" interference, which makes the communication link between drones and remote controllers invalid, thereby forcing drones to hover, return or land.
Specific working principle
Electromagnetic interference (EMI): drone jammers interfere with the communication link, navigation signal or control signal of drones by emitting radio waves of specific frequencies, causing them to lose positioning, navigation or remote control signals.
GPS interference: Use GPS jammers to send misleading signals to drones, making it unable to accurately obtain satellite signals, resulting in positioning deviation or loss of navigation capabilities.
Signal shielding: By emitting shielding signals of specific frequencies, drones cannot receive control signals or transmit data.
Optical interference: Use strong beams or lasers to interfere with the optical sensors and cameras of drones, reducing their visual recognition and target tracking capabilities.
