From the World Cup to F1: Why regulators choose the RFeye Node for major events

We see why the RFeye Node has been a key component in ensuring the success of major global sporting events. Securing 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 the hosting countries. The UEFA Euro 2016 tournament in France [...]

How accurate is TDOA geolocation

by Michael Knott 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 [...]

Direction Finding RMS error: Lies, damned lies and statistics

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 [...]

Geolocation in post-processing

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 [...]

How to deal with GPS jamming and spoofing

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 [...]

Terrain Analysis

RFeye software includes a terrain analysis tool allowing you to easily optimize receiver placement by visualizing obstacles between candidate receiver and transmitter locations. This makes it a very useful tool in network planning. The image below shows how several terrain analysis functions can be applied to a network at once in order to visualize elevation variations between two points. As we can see, the terrain [...]

Cumulative Tracking with Direction Finding Vehicles

CRFS’s Cumulative Tracking feature allows single or multiple transmitters to be located in complex multi-path environments using just a single antenna array RFeye software facilitates single receiver geolocation with its AOA Cumulative Tracking feature. As shown in the image below, a location is gradually built up over time using the multiple Lines Of Bearing obtained as the vehicle-mounted receiver moves. Left to right: Antenna Array, [...]
