S22A UAV Deception Defense System is specially developed to deal with various security threats brought by “low, small and slow” UAVs. By transmitting low-power regenerative security navigation satellite signals (power no more than 10dBm), it intrudes into the navigation system of “low, small and slow” UAVs, thus realizing the interception and control of UAVs that need to use the navigation system for flight control, so that they cannot fly into the protected area. By transmitting low-power regenerative safe navigation satellite signals (power greater than 10dBm) to invade the navigation system of “low, small and slow” UAVs, it can realize the interception and control of UAVs that need to use the navigation system for flight control, so that they can’t fly into the protected area and safeguard the low-altitude safety of the area, meanwhile, the S22A UAV Deception Defense System can be expanded to produce a wide range of professional applicable products.
