UK Firms Successfully Develop Technique That ‘Freezes’ Drones During Flight

Authorities who were concerned about drones flying in sensitive areas may have finally got a solution.

Three British companies have created a new technique that can freeze drones in mid-flight and prevent them from entering sensitive areas.

So, what is the technique and how does it work?

The Anti-UAV Defense System (Auds) works by covertly jamming a drone’s signal, making it unresponsive.

A drone flying in sensitive airspace can be detected by the Auds radar and then sighted via a camera equipped with thermal imaging capabilities so that it can be targeted visually.

Then, a high-powered radio signal can be focused on the drone – essentially overriding the connection to whoever is operating it.

After this disruption, the operator is likely to retrieve the drone believing that it has malfunctioned or  it can be frozen until its battery dies and it crashes.


Surprisingly, the whole process takes as little as 25 seconds.

Paul Taylor of Enterprise Control Systems, which developed the product along with Blighter Surveillance Systems and Chess Dynamics, said:

“There are a number of frequency bands that are used by all of the manufacturers. We transmit into those frequencies in the direction of the UAV (Unmanned Aerial Vehicle) using a directional antenna. There’s quite a lot of radio power on to the UAV – so much so that it can only hear our Auds signal.”

Auds has been tested in the UK, the USA and France, said Taylor, and government organisations in all three countries had been involved in those tests.

The success of the tests means that these governments will eventually integrate this technology into their defence systems. Since drones are fast becoming the preferred choice of carrying out critical missions, countries will find the Auds technology immensely useful.
