RFeye shown on monitor screenRFeye® Site is our state-of-the-art desktop application for all your real-time monitoring and geolocation requirements. It includes all the essential functionality needed for spectrum monitoring and management tasks such as: carrying out RF spectrum sweeps; IQ capture; measurements of power, occupancy, bandwidth and frequency deviation; and visualization via interactive charts and graphs. However, RFeye Site goes far beyond this with a vast array of advanced functionalities combined in one software suite which is ideal for the RF expert. This includes:

  • Indoor and outdoor real-time geolocation (including AOA, TDOA, POA and hybrid)
  • Detailed interactive mapping of Node networks and geolocation results
  • Alarms and triggered missions (e.g. sweep, IQ capture, geolocation) in response to frequency mask breakages
  • Signal classification
  • Post-analysis of recorded signals (including geolocation)
  • 3D TDOA geolocation for aircraft and drone tracking
  • Propagation modelling to optimize receiver networks for required coverage
  • Simulation capabilities for testing of monitoring and geolocation scenarios

The value of this extensive range of capability is maximized with our multi-mission capability enabling multiple spectrum monitoring and geolocation tasks to be run simultaneously on the same Nodes.

RFeye Site can be customized according to your application requirements by including or excluding optional plugins. Contact us if you’d like to discuss your needs further or continue reading to find out more about Site functionality.

RFeye Site monitoringCRFS knows that those charged with monitoring and management of the RF spectrum need to carry out essential measurements in a more effective and efficient way. RFeye Site allows all the basic measurements to be carried out, including frequency, power and frequency deviation according to relevant ITU recommendations. Data from receiver networks comprising many Nodes, Arrays and other RFeye hardware can then be overlaid and analyzed with customizable charts and measurement tools.

Detailed and fast updating real-time monitoring in our software is enabled by the exceptional performance of our hardware ensuring capture of short duration and low power signals. Frequency masks can also be set up on particular bands and channels with mask breakages used to trigger tasks such as recording of signals of interests, geolocation or even triggering of 3rd party alarm systems.

Monitoring scenarios can also be simulated with simulated receivers and transmitters allowing illegal and/or dangerous monitoring scenarios to be simulated and tested in a virtual environment.

Our geolocation software has been designed for optimized performance indoors and outdoors utilizing our industry-leading Nodes and direction finding Arrays. RFeye Site enables multiple targets to be tracked over wide areas in real time with extremely fast update rates ensuring accurate tracking of emissions even from fast moving vehicles. We use multiple geolocation techniques (AOA/DF, TDOA and POA) as well as hybrid geolocation which combines all of them. With the fantastic accuracy and update rates of our geolocation algorithms, this means hybrid is not just providing the ‘best of both worlds’ but the even better of many worlds.

In response to customer requirements, we have also recently developed our geolocation in post-processing feature. This allows TDOA geolocation to be carried out on recorded signals allowing for example, post-event diagnosis of interference incidents.

Simulated geolocation scenarios can also be carried out using our receiver and transmitter simulation tools. This can be used to train staff on interference hunting without requiring a real source of interference to be set up.

We have a specialist set of tools for indoor geolocation and Technical Surveillance Countermeasures applications. This package is optimized for detecting and locating signals of interest for in-building applications – for example, surveillance devices or hidden cell phones. Frequency masks can be set up to alert a security guard on detection of a suspicious signal with an indoor location overlaid on the building floorplan. Read more about our RFeye Guard system for in-building monitoring and geolocation.

3D TDOA (or 3D WAM) is a recent advance in our geolocation software enabling 3D passive tracking of targets in three dimensions even with a ground-based network of Nodes. This is used to track objects such as military/civilian aircraft, commercial drones and more advanced military UAVs. As the method is entirely passive it allows targets to be tracked without any emissions which may alert those targets.

RFeye Site signal classification in screenOur signal classification plugin allows signal types to be accurately identified using machine learning technology. Our research and development in this area has allowed us to enhance classification accuracy as well as supporting the classification of new and unrecognized signal types.

Typical military uses of this capability include classifying signals to support identification of unfriendly forces and gather intelligence on their capabilities e.g. identifying emissions from weapons control systems, specific communications protocols etc.

Signal classification can also help diagnose RF interference and identify signals which are out of band. Also see signal verification.

As we develop this product further, customers will be able to independently add their own signal types to allow the classifier to work on signal types which may be classified and hence not available to external software providers such as CRFS.

Our propagation modelling tools allow signal propagation to be simulated taking full account of earth curvature effects, terrain obstacles and custom user-created obstacles. This allows the performance of Node networks for monitoring and geolocation coverage to be analyzed prior to hardware purchase or real-world installation. Using our terrain analysis tool, Nodes can be repositioned to best optimize performance in the virtual world before deployment in their corresponding real-world locations.

RFeye Map allows large spectrum datasets from fixed and mobile spectrum monitoring to be managed and analyzed. Spectrum usage can be visualized with map overlays to get a clear indication of where spectrum is congested or not being used efficiently and how this is changing over time. National spectrum regulators use Map to spot long-term spectrum trends and this information can then be used to inform policy and decision-making.

Signal verificationSignal verifier is a tool primarily aimed at regulatory customers to allow automated identification of license violations. This plugin provides an easy to interpret spectrum overlay to identify transmissions which are not of the expected type for the band in which they are transmitting.
