The fake gps navigation decoy device is specially developed to deal with various security threats brought by UAVs. By radiating low-power regenerative navigation satellite signals (the power is no more than 1W), it can invade the UAVs navigation system, so as to intercept and control the UAVs that need to use the navigation system for flight control, so that it cannot fly into the protected area and ensure the low- altitude safety of the area.
