„Flight training for beginners – How to get your drone under control“ headline SPON end of July this year. According to a report by the German Air Traffic Control (DFS), it is currently assumed that there are more than 400,000 drones in Germany, most of them in private hands. Besides hobby drones, the unmanned aerial vehicles, as they are correctly described, have a long military tradition. Not least for this reason, safety circles have been discussing for some years what threats drones pose and whether they can actually be used for economic and industrial espionage or for terrorist attacks. And if so, how to prevent it.
So if you want to invest in drone defense, you should first find out what kind of threat is actually caused by drones for a company or an organization. In principle, there is not much that is needed to plan a drone mission: commercially available drones with the associated controls are available on the Internet, while laptops, tablets or smartphones are used for image transmission. In addition, drones can be equipped relatively easily with additional camera systems such as night vision, thermal imaging cameras or sensors for W-Lan spying. Nevertheless, it is not nearly as easy as one might think to use drones for spying.
But there are scenarios where the threat is quite real. Prisons have had to deal with the fact that drugs or phones were smuggled in with drones. Increasingly, drones are also being considered in event security concepts. Even civilian flying drones are currently able to carry a weight of 100 kilograms. Terrorist attacks on this path are conceivable. At present there have not been any significant personal injuries, but there have been and there are enough incidents. Interested parties who are seriously considering drone defense are often not sufficiently familiar with the legal framework in Germany.
The most important requirement is the detection of the aircraft drone. For example, you can supplement existing video surveillance systems and video analysis. The software then triggers an alarm on flying objects of a certain size. Every commercial drone (no self-build) has unique identifiers, and they can be detected with sensors. This is a way to detect drones. As well as radar or detecting over typical acoustic patterns. Others recommend again to combine all the known technologies. Basically, it is a relatively young market and a lot of research is done.
Incidentally, since December 2015, drones must not only be registered with the American aviation authority FAA, but also carry a type of license plate. In Germany there are similar efforts.
Difficult is the actual defense of the buzzing threat. Not everything is allowed here that pleases. Some manufacturers rely on Geofencing, a kind of programmed fence based on GPS. GPS spoofing, the disruption of the radio signal, is controversial and not allowed everywhere. In addition, there are more military defense methods with the help of drones, net cannons, firearms, lasers or even birds of prey, as tested in the Netherlands. Since the end of last year, Deutsche Telekom has also been involved in the protection against drones. The systems are primarily intended to protect places such as airports, sports stadiums, car test tracks or major events with celebrities.
