Securing industrial sites from trespassing drones

On another instance last October in France, drones were reported to have been caught flying over the country's state-operated nuclear power plants. The incident stirred a lot of debate about nuclear plant security and highlighted the bold fact that no one had been able to prevent nor trace these repetitive intrusions.

The fact that French Gendarmerie may be allowed in the future to shoot down such trespassing drones (using firearms) may not be a deterrent against a swarm of malevolent drones and could also cause collateral damage. Securing large industrial sites against non-authorised drones is still an issue, but drone geo-fencing countermeasures are already in the making.

Just a few weeks after these events, during electronica, I stopped by the IMST GmbH booth where a radar-bearing drone was exhibited. Here, Siegfried Schulze, responsible for business development at the research-driven industrial engineering and design house, told me that an increasing amount of research was taking place to come up with preventive measures against such drone intrusions in established no-fly zones.

Talking about no-fly zones, if you buy a small drone, a notice is usually included in the box warning that it's pretty much illegal to fly it anywhere in populated areas or anywhere you could put someone at risk (the definition is as broad as it is vague except for airport routes or specific flying zones mapped in aeronautical charts).

Catcher drone

But this in itself won't prevent any malicious flights, and judging by the number of camera drones that are offered to consumers and pro-users alike to map and record their surroundings, it is inevitable that more drones will venture beyond the strictly private boundaries of a garden or a living room.

"For the next months to come, until the industry comes up with drone interception solutions, drones will represent a new potential threat to a lot of industrial sites," warned Schulze who leads a research group on special security systems and is active in the German UAV DACH working group. According to Schulze, there will definitely be a market for catcher drones.

So what could be done to intercept a drone before it causes any harm?

"First, you want to identify it, know exactly what drone it is, what radio link it uses and possibly communicate with it. Then you want to stop it before it trespasses the site's boundaries, then you want to catch it or take it down," explained Schulze.

"Here we are exhibiting a high precision 3D radar technology light enough to be used on-board drones for anti-collision and flight control, but it could also be used to exactly pinpoint and locate simultaneously other drones, learn about their speed and flight direction."

"We are also developing sensor and radar solutions in order to determine the unique acoustic, thermal, EMI and optical signatures of any given drone," he added, "because you don't want to raise false alarms every time a bird flies over your site."

Practically, the idea would be to record these multi-domain signatures for all known commercial drones and have their unique signatures ready in a database for quick profile matching and 100 per cent physical identification.
