As COVID-19 continues to disrupt normal life across the globe, we’re all having to adapt to the (hopefully temporary) new reality of working remotely. As part of that process, we wanted to reach out directly to our customers and to the wider RF community by organizing a series of interactive webinars. We’ve chosen a selection of topics that we hope will prove useful and [...]
What are LEO satellites, what can they be used for, and how can they be tracked using RF? In this blog, we will find out. Low Earth Orbit (LEO) satellites are far from a new phenomenon (indeed, the very first satellite, Sputnik, was an example back in 1957), but they are attracting increasing interest for their current and potential future uses in financial services, [...]
Security & Policing is THE official Government global security event, offering a world-class opportunity to meet, network and discuss the latest advances in delivering national security and resilience with UK suppliers, colleagues and Government officials.
Quick Read Summary: A new training video from CRFS to help users of 'Radio Direction Finding' (DF) Arrays understand the importance of multipath. The video animation is designed to help users visualize real world environments in terms of multipath/RF reflections. Different object models are used alongside materials that reflect RF differently to demonstrate the principle. View the full animation here RF Training A slightly [...]
A fully functioning radar provides crucial situational awareness in a wide variety of military settings. And as a key component in the electronic warfare arsenal, it is likely to be the target of countermeasures by opposing forces designed to degrade friendly capabilities, most likely some variety of radar jamming. This can range from straightforward brute-force jamming attempts, where an overwhelmingly powerful wideband RF signal [...]
In a recent blog post, we described how 3D TDOA could be used to detect spoofed ADS-B signals from aircraft. And it’s fair to say that the area around an airport is a heavily congested area, with large numbers of planes constantly coming and going. If you’ve got some familiarity with TDOA, though, there might have been something nagging at the back of your [...]
The Annual AOC International Symposium and Convention is the leading event for electronic warfare, electromagnetic spectrum operations, cyber-electromagnetic activities, and information operations professionals from around the world. CRFS will be exhibiting on booth #211. [email protected] New products and capabilities demonstrated at AOC New for 2019: RFeye Mission - Automated spectrum monitoring 3D TDOA - 3 Dimensional geolocation for Aircraft and cUAS CRFS will be demonstrating [...]
In a rapidly emerging field like drone detection, it can be difficult to separate fact from fiction. At CRFS, we've got years of experience designing and deploying drone detection and geolocation systems, so we thought we'd do our bit by collecting some of the myths and misconceptions that we’ve come across, and trying to clear them up in this blog. 1) All you need [...]
What is AIS? The AIS (Automatic Identification System) is designed to allow ships, boats and other maritime vessels to provide information about their identity, position and heading to other vessels and base stations. It works by broadcasting information using RF signals that can be detected by other users with AIS equipment. This data is transmitted over the maritime channels 87B (161.975 MHz) and [...]
ADS-B Basics Automatic dependent surveillance-broadcast (ADS-B) is a surveillance technology currently being introduced in the US (Next Generation Air Transportation System), Europe (Single European Sky ATM Research) and across the globe. It functions as a replacement for secondary surveillance radar, and possibly even to replace primary radar in future, for air traffic monitoring and control. It requires planes to determine their current position using [...]
