We see why the RFeye Node has been a key component in ensuring the success of major global sporting events. Securing the RF spectrum at major events is a crucial part of the national spectrum regulator’s role. Major sporting events such as the Olympics and F1 world Championship can mean big money for governing bodies and hosting countries. The UEFA Euro 2016 tournament in [...]

SOF (Special Operations Forces) must act with the highest levels of discretion in hostile and often unfamiliar environments. In these scenarios, real-time RF situational awareness is vital for ensuring friendly forces remain undetected and detecting enemy activity. However, this vital capability must be weighed (literally) against the need for forces to be able to carry the equipment and remain agile. So what levels of situational [...]
With the threat from radio surveillance devices re-emerging, Jon Bradley looks at the problem of reliance on manual bug sweeping strategies and how the alternative of a continuous real-time In-Place Monitoring System (IPMS), such as CRFS’s RFeye Guard system, can enable true 24/7 vigilance in secure buildings and facilities. Cyber security is continually in the news and is the focus of significant efforts and resources [...]
By Dave Robertson, International Sales Manager for Defence and Security As the premier event for the global Defence and Security market, DSEI was the place to be seen last week for many companies including CRFS. Of course, the biggest challenge was achieving the balance of meeting key suppliers and customers, and hearing from the numerous distinguished keynote speakers. Whilst innovation was once again a key [...]
TDOA (Time Difference Of Arrival), also known as multilateration, is a well-established technique for the geolocation of RF emitters. Using three or more receivers, TDOA algorithms locate a signal source from the different arrival times at the receivers. We trust that existing users of CRFS’s TDOA geolocation know, from their own experience, that it is very accurate and effective for most signal types. New [...]
By Filip Zganec, Regulatory Sales Manager, CRFS Is the RMS error of a DF system as important as some manufacturers would have you believe? Some of our competitors go to extraordinary lengths to talk up the significance of 1° RMS error and to get it specified in tenders as the supposed gold standard. Ever wondered why? It’s because they can limit the competition and can [...]
Just seen an interesting transmission appear on your spectrum, but now it’s disappeared? Need to know where it came from, but you weren’t running a geolocation task at the time? Tough luck, it’s gone forever. If you’re lucky, you can sit there staring at your screen and it might pop up again. Sounds ridiculous? That’s what we thought, which is why we’ve developed our geolocation [...]
CRFS’s next generation intelligent radio receivers, or RFeye Nodes as we call them, allow multiple users to run multiple independent sets of monitoring and geolocation tasks simultaneously using the same hardware. This maximizes your return on investment. Distributed networks may vary from a few Nodes over a small area like a building, to hundreds of Nodes across a whole country. Users can log on to [...]
Radio receiver technology is advancing with larger available instantaneous bandwidths at high resolution. However, for desktop-based or portable systems connected to a PC, this higher performance is constrained by the relatively low speed data transfer capabilities available over USB. CRFS is pioneering Thunderbolt™ 3 connectivity in our portable spectrum monitoring solutions to enable full rate high fidelity 16-bit data transfer is achievable. Many spectrum monitoring [...]
From ship navigation to financial transactions, we’re increasingly reliant on GPS. Jamming and spoofing can therefore cause significant disruption and represent a public safety threat. Fortunately, spectrum monitoring allows detection and location of jammers and the possibility to pre-empt attacks with anti-jamming and anti-spoofing technologies. During an L1 and L2 GPS band monitoring campaign over just a few weeks in London, we detected significant jamming [...]
