Handheld UAV jammer introduction

The handheld UAV jammer is a UAV defense product released by our department. By disturbing the data link and navigation link of the UAV, the communication and navigation between the UAV and the remote control are interrupted to force the UAV to land or drive away automatically to ensure the safety of the low-altitude airspace. This product is compact and lightweight, easy to carry and operate, and can be quickly deployed according to needs. It can be widely used in airports, prisons, water (nuclear) power plants, government agencies, important meetings, large gatherings, sports events and other important places.

As we all know, drones usually rely on GPS signals for positioning, and GPS relies on medium-orbit satellites. In popular terms, the signal is very weak when it reaches the Earth's surface after tens of thousands of kilometers. Therefore, when the UAV is close to the defender, it is more convenient to perturb the GPS signal. To deceive it, it is necessary to use a more complex method to simulate the GPS satellite, which will be a very difficult thing. At present, the UAV control mainly uses radio communication technology, which can send high-power interference signal to the target UAV and suppress the control signal to force the UAV to land or return by itself.

There are 3 types of drone interference:

1) The use of hand-held UAV jammers requires personnel investigation, and it is found that manual intervention is controlled by hand-held UAV jammers;

2) Distributed UAV jamming The distributed UAV jammer is mainly based on a relatively large control area to avoid the UAV entering the controlled area, which greatly reduces the security risk; It doesn't take a lot of people to do it; Control.

3) Radar-type anti-jamming device, expensive, is its primary problem, usually can not be used.
