Ouranos RF Scanner

Designed for Detection and Direction Finding of Drones

Ouranos RF Scanner is designed for detection and direction finding of commercially available drones equipped with a video broadcasting system operating in the standard frequency bands, and also for the detection and direction finding of drone ground station control signals. Not only the direction but also the position of the source can be determined if at least two or more sensors detect the signal.


  • Fully automated system design

  • User-friendly graphical user interface

  • Capable of detecting multiple targets on multiple frequency bands and target display on the map

  • Providing location information on both the drone and the controller

  • Integration to large scale alarming/ protecting systems

  • System scalability according to the field requirements

  • Software-based system improvement for new types of signals

RF System Advantages

OURANOS-RF utilizes the classic AoA type of direction-finding method. This solution provides the best performance with fast response time and fewer limitations. The main advantage is that as soon as any of the sensors capture the signal of interest, the user will get an alarm with direct information included. In many cases, this information is enough for the responsible personnel to trigger the counter activity. As soon as two or more sensors detect the signal, the OURANOS-RF can provide location information as well.


We can customize the system design, as well as support the system delivery and launch according to the customer requirements. This covers the RF coverage calculations(based on publicly available digital elevation/terrain models), site survey/deployment  selection, power feed installation guidance, on-site training for the operation personel, etc.

RF Performance

In real life, we come across plenty of RF emitting devices irrespective of the location. There might be many interfering signals in a specific band of interest (e.g., 802.11-WiFi standards, Bluetooth, ZigBee, etc.) against which the system should perform well. The overlapping signals could degrade the detection performance, classification, and direction-finding. We took these constraints into consideration right from the early stages of the development in order to create a system that can cope with very low SNR and overlapping interference signals. Our systems can also perform very well in the case of strong out-of-band RF signals (e.g., near-field radars, mobile base stations, PMR stations, repeaters).
