Germany does not have adequate defenses against drones, said Jan-Eric Putze, the managing director of German company Droniq specializing in drone traffic management and integration into civilian and commercial air traffic. In his opinion, the country lacks a system that would provide a comprehensive picture of drones and other flying objects in its airspace. He suggested radio frequency (RF) scanning, aimed at tracking the frequencies typically used for remote drone control, as the first and most accessible method. It will allow the detection and tracking of the vast majority of drone movements, he continued. Based on the threat level to the protected facilities, the use of passive radars could provide the next possible level of protection.
