This product is highly integrated and uses electronic jamming technology to implement precise countermeasures against drones within 500 meters. Multi-band electromagnetic emission, ready to use, cuts off the remote control, image transmission, and navigation links of the drone at a long distance,...
The No-fly zone device is mainly aimed at GPS/GLONASS/BD navigation systems, launching false satellite navigation signals to form a no-fly zone function, and drones cannot fly into the no-fly zone. The device has low radiation power, has no effect on the surrounding electromagnetic environment, a...
Low-altitude surveillance radar is mainly used to detect ground, sea and low-altitude targets. It has excellent anti-interference ability, ground/sea clutter suppression ability, and can actively detect and track targets.
he Passive RF Detection system analyzes and identifies the remote control signal and data return signal of drones, detectes target and early warning
Navigation Tricking System launch fictitious satellite navigation signal, block the real navigation signal in the air, falsify the navigation system of drones, change the auto location of drones, induce the drone to make a false response and get away from
