UAV Navigation Deception Device


I. Function of UAV Navigation Deception Device

Anti-drone active defense system, through the radiation of low-power navigation deception signal, the invasion of GPS, GLONASS, BeiDou and Galileo and other navigation of the drone satellite navigation components to block and deceive, to achieve all-weather, all-weather, all-weather, all-direction of the drone to drive away, forced landing, out of control, etc., so that the black-flying drone can not intrude into the protected area, the equipment can be used individually, but also can be grouped together to use the network.

II. Main features of Drone Navigation Decoy System

1. Equipment is safe and reliable. Applicable scene security weak explosion-proof design.

2. Variety of striking modes. Support single-point fixed position, uniform linear motion position, defense circle circular motion position, interference deception and other defense modes.

3. Equipment unattended. The device can be switched on for 24 hours to implement deception and interference, and the whole process does not require manual operation.

4. Remote control. Remote control can be implemented to adjust the striking time, striking distance and so on.

5. Optional working mode. It can work 24 hours a day in a single station or 24 hours a day in a group network; it can work independently or be integrated into the system to work in a triggered manner.

6. Deception signal is real. The satellite state and position in the deception signal are consistent with the real situation in the sky, and the time information in the deception signal is synchronized with the real situation in the sky at the code level.

7. Adjustable equipment parameters. The deception interference object can be adjustable, can interfere with one or more of GPS, Galileo, Grenes; deception distance can be adjustable, can be adjusted according to the size of the protected area within the range of 1,000 meters; signal transmission power can be adjustable, can be adjusted according to the actual needs of the transmission power.
