At present, under normal circumstances, the vast majority of drone users will prefer GPS navigation for flight control, while civilian GPS signals are non-encrypted, which leaves space available. The main principle of GPS deception is to send false geographic coordinates to the control system of the drone, so as to control the navigation system and induce the drone to fly to the wrong place. The drone jammers intercepts the GPS WiFi frequency band used by the drone, affects its flight, and forces it to land.
The GPS signal can be generated by the generator, or it can be recorded beforehand and then played back. Because the drone receives GPS signals always based on the strongest signal source, as long as the artificial GPS signal on the ground is strong enough, it can cover the real GPS signal transmitted from space, thus deceiving the drone. The GPS receiver module, while the uav scrambler officially forced the drone to land and return home by transmitting a more powerful signal.
