CRFS provides intelligent systems for real-time monitoring and management of the RF spectrum. Their systems (RFeye Nodes and RFeye Arrays) can be deployed indoors or outdoors to autonomously and continuously monitor spectrum, sending data in real time over IP to a remote operator. The intelligence of the RFeye spectrum monitoring systems allows tasks to be scheduled and key insights to be highlighted, removing the need for operators to observe spectrum 24/7.

The quest for illicit intelligence is a never-ending threat; from criminals trying to obtain information for financial gain, to sophisticated state-sponsored adversaries looking for political and military gains. While we do not always know what kind of threats are around us, a robust security policy encompassing physical security, cyber security and protection from electronic surveillance is needed to ensure secrets remain secret. The security of your building, your Sensitive Compartmented Information Facility (SCIF), your private conversations, your plans and secrets can all be compromised by small, inexpensive surveillance devices (GSM bugging devices are available today from well-known online retailers for less than $50).

Critical National Infrastructure (CNI), typically defined as assets essential to the safety, security and economic well being of a country, require the highest levels of protection to prevent, mitigate and enable effective response to risks. Those charged with Critical Infrastructure Protection (CIP) face a heavy responsibility to ensure the risk of disasters (including loss of life and severe economic damage) are minimized as far as possible. Governments also impose strict regulations surrounding the protection of national infrastructure, meaning that even where there are no consequences to an unmanaged risk, organizations can still face financial penalties for failing to address it.

Drones and UAS (Unmanned Aircraft Systems) have many positive and legitimate uses but there are increasing concerns that drones are being used for illegal and dangerous activities: flying too close to passenger aircraft, smuggling drugs/weapons into prisons, privacy concerns and even weaponized drones. The list grows daily, as do the incidents.  RFeye Drone Defense is a passive RF sensing system that geolocates drone & operator emissions in 3 dimensions: latitude, longitude and altitude. The system can track multiple drones simultaneously and alert operational/security staff to the confirmed presence of a drone and its location, all in real time.

 RFeye AirDefense is a wide-area 3D geolocation and intelligence system that can identify and track aircraft while remaining invisible to electronic detection. Its covert nature makes the system ideal for border monitoring, radar augmentation, target acquisition, spoofing detection and more. RFeye AirDefense solution uses 3D TDOA to achieve highly accurate tracking of RF emissions from objects such as enemy aircraft without emitting any electromagnetic signature that may give away your presence.

The Array 300 is an intermediate-sized system for vehicle-mounted deployment or fixed installations. It is available in two different receiver configurations based on the class-leading RFeye Node 100-8 with 100 MHz IBW and 8 GHz upper frequency, or Node 100-18 with 100 MHz IBW and 18 GHz upper frequency.

The Array 300 uses a unique multi-layer approach that is more sophisticated and versatile than traditional direction finding. High-performance spiral directional antenna modules are optimized for different frequency bands and arranged in multiple orientations. The Array is sensitive to the majority of incoming signal polarizations including all linear polarizations, allowing reliable detection of signals including those invisible to most DF systems.

The Array 500 is the “big brother” of the Array 300 and is for fixed installations. It contains larger spiral antennas on the lower tier, allowing accurate AOA measurements down to 100 MHz. It is available in two different receiver configurations based on the class-leading RFeye Node 100-8 with 100 MHz IBW and 8 GHz upper frequency, or Node 100-18 with 100 MHz IBW and 18 GHz upper frequency.

Feye Guard is a continuous TSCM (Technical Surveillance Countermeasures) solution that combines highly sensitive and broad bandwidth receivers with simple autonomous software to ensure you never miss an illicit signal.

The high-specification receiver technology is able to detect low-power and advanced signals that would be missed by many handheld sweepers. And since electronic surveillance devices are not guaranteed to operate in obvious parts of the RF spectrum, the ability to continuously monitor the spectrum up to 18 GHz is a critical feature built into our systems. Sweep rates of almost 400 GHz/s and a resolution down to 1 Hz enable the highest possible probability of interception to be achieved.
