FAQs
SHOPPING WITH US
How does drone jammer work？
1.Signal blocking technology:
(1) Communication link interference: strong interference signals are emitted to the wireless frequency bands (such as 2.4GHz and 5.8GHz) between the drone and the remote controller to disrupt data transmission. For example, when the drone cannot receive control commands, it may trigger the “lost control return” or hovering mechanism.
(2) Navigation signal interference: suppress or forge satellite navigation signals (GPS, Beidou, etc.), making the drone positioning invalid, resulting in flight trajectory deviation and inability to hover stably. Some jammers can simulate false coordinates to make the drone “misjudge” its position.
2.Intelligent deception control:
Advanced jammers can simulate the remote controller protocol and send false commands to the drone (such as “force landing” and “fly to a designated location”) to achieve “hijacking” of the drone. For example, by parsing the drone communication protocol, forging legitimate command data packets, and bypassing encryption verification.
