In just a few years, drones have gone from niche to popular. Because of its rapid development, the safety hazards and accidents caused by the drone "black fly" have been repeatedly banned, so the anti-UAV counter system will also be operational. So what kind of methods do the "natural enemies" of these drones use to encircle drones?
Disruptor drone signal; this type is generally suitable for the current UAV flooding, widely used anti-UAV mode, drone disruptor is the most extensive UAV Blockers. The drone jammers mainly transmits directional sound waves or radio frequencies to the target drone, interferes with the hardware of the drone or cuts off the communication between the drone and the remote controller, thereby forcing the drone to land or return by itself.
Signal disruptors: The simplest and straightforward way to block interference is signal interference, which is relatively low in technology and less costly. At present, most UAVs on the market use a combination of GPS satellite navigation system and inertial navigation system. It is not difficult to disturb the GPS signal. The UAV jammer only needs to transmit to the target UAV. The directional radio frequency of the power can be obtained. After the GPS signal of the drone is interfered, the accurate self-coordinate data cannot be obtained, which will cause the drone to lose control to a certain extent, so that the operation fails. This method is also the mildest of the many "encirclement and drooping" drones. It does not allow the drone to fall. It is a way to reduce the "harmful purpose" of drones by interference.
