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.


  • Powerful detection and direction finding capabilities on all UAV frequency bands
  • Location estimation with simultaneous detection of multiple (at least three) sensors
  •  Automatic operation with 7/24 hours support
  • User-Friendly control interface
  • Alarm indication and automatic notification (software option, SMS or e-mail)
  • Encrypted standard interface is available upon request for system integration
  • Weather proof design for outdoor devices
  • Remote Control : Ethernet interface (both near and far remote control are available)
  • System scalability according to the field requirements

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).
