Still in the UK, Rinicom proposes its SkyPatriot, an optic-based UAS detector with a detection range of over 1 km. The 520 mm diameter, 5 kg system includes a 7.513.5 µm thermal sensor with a 150 mm lens and a colour optic sensor with a x30 zoom; according to Rinicom detection range varies between 1 and 8 km, the system allowing simultaneous detection of more than 10 drones flying up to 25 m/s with minimum size of 5 cm. Robin Radar Systems of the Netherlands, specialised in bird radars (its name derives from the TNO project name: Radar Observation of Bird INtensity - ROBIN, the company being a spin-off of TNO) developed a sensor dedicated to drone detection. Known as Elvira, the company aim was to produce an affordable system, with a much lower price than derivatives of military radars. An FMCW X-band radar with a weight of 82 kg, it has a detection range of 3 km and a classification range of 1.1 km against drones, coverage being 360° in azimuth and 10° in

elevation, with azimuth resolution of 1° and range resolution of 3.2 meters. Controp of Israel proposes its Twister lightweight passive IR scanning system, which covers a 360° sector with a scan frequency of 1 Hz. It can be backpacked by two people or mounted on fixed installations.
DroneCatcher, the Dutch solution In the Netherlands Delft Dynamics developed the DroneCatcher under the auspices of the Ministry of Security and Justice, the Royal Netherlands Marechaussee and the National Police. The system is based on a multicopter “armed” with a compact mechanically shooting net system. Once the target is identified by a ground sensor, the DroneCatcher flies towards it, maximum speed being 20 m/s, multiple onboard sensors allowing to lock the net gun on
