Uav, as a new aircraft, has been widely used in military, civil, entertainment and other fields. But at the same time, drones also bring some security risks and challenges, such as illegal invasion of drones, malicious surveillance, terrorist attacks and so on. How can we effectively defend against and counter these threats? The traditional methods include interception, interference, destruction, etc., but they all have their own limitations and risks. Today, we're going to introduce an anti-drone technology: navigational decoy.
Navigation decoy is a technology that uses satellite signals to deceive and control drones. Its working principle is to generate a navigation satellite positioning code signal with the same frequency and time synchronization through simulation, inject the guidance information into the unmanned aerial vehicle navigation system, indirectly obtain flight control, and achieve a variety of tactical functions such as no-flight, drive away, and track guidance.
What are the advantages of a navigation-decoy drone defense system?
First of all, it can carry out omnidirectional or directional defensive attacks on multi-rotor or fixed-wing UAVs in various stages such as standby, take-off, cruise and hover within the defense range.
Secondly, it can realize the control and guidance of the UAV without destroying the UAV itself, avoiding unnecessary losses or consequences.
Finally, it can work in conjunction with other anti-drone equipment such as radar and electromagnetic interference devices to improve the efficiency and effectiveness of countermeasures.
So, in what scenarios can you use navigation to trick drone defenses? For example:
Protecting leaders or VIPs from drones at important venues or events;
Prevent illegal reconnaissance or attack by UAVs in sensitive areas or facilities;
Jamming or capturing enemy UAVs during military exercises or war;
Command or coordinate friendly UAVs in public safety or emergency rescue.
