The Asia-Pacific is the frontline between competition & conflict. Grey-zone tactics, increased militarization, and border disputes are reshaping the region’s security landscape. Dr Thomas Withington’s special report examines how electromagnetic sensing can strengthen deterrence, enhance situational awareness, and prevent escalation. 

Silvus Technologies provides sub-systems for defense companies and system integrators requiring RF capabilities in larger systems or platforms. This guide introduces solutions and applications.

Maximize your ISR capabilities for air, maritime, and land operations. RFeye proven RF sensor integrated into a high-performance tethered drone enables variable-height monitoring of VHF, UHF, and SHF transmissions. It supports tactical surveillance, geolocation as part of a TDoA network, signals intelligence, and over-the-hill reconnaissance to enable rapid decision-making.

Designed with an Uncrewed-Vehicles Platform Manufacturer for a NATO member, Silvus Technologies created a self-contained spectrum monitoring and TDoA system that fits onto a Group 1 USV. The system facilitates ISR missions for the VHF and UHF bands in hostile environments.

A robust, reliable extension for intelligence and electromagnetic EW system direction finding in a tactical form-factor. The system is small, rapidly deployable and ruggedized. It is suitable for stationary and mobile (dismounted) deployment.

Ultra wide frequency, high performance radio direction finding up to 40 GHz.

High performance twin channel system for simultaneous wideband radiomonitoring and direction finding.

This guide explores critical strategies for identifying and managing these risks, including RF interference detection, VHF and ILS compliance, GNSS jamming countermeasures, and advanced drone detection methods.

This white paper discusses how adding RF technology to existing port security measures can help augment port protection and security.

RFeye Site Simulator provides EW operators with simulated RF sensors. This powerful tool can be used for teaching spectrum operations and conducting wargames, allowing EMSO professionals to simulate scenarios and resolve tactical problems. 

Dr Withington’s in-depth analysis highlights essential lessons from the conflict for future warfare. NATO forces can no longer assume spectrum dominance and will likely depend on passive, networked, unattended sensors across the battlefield.

This white paper was guided by the results of a border security survey aimed at border control, border security, and military personnel tasked with national security and defense. It examines how RF sensor technology can be used to tackle modern border security threats.

The RFeye Node 100-18 LW offers the same high performance and real-time spectrum operations as our standard RFeye Node 100-18 sensor, but in a smaller, lightweight form well suited for all types of autonomous systems and operations needs

Silvus Technologies provides a range of APIs, and by leveraging them customers can seamlessly integrate the capabilities of CRFS software into their proprietary systems, thereby automating tasks, which would otherwise have to be performed manually.

This white paper provides an overview of contemporary radio spectrum monitoring and the sensor and geolocation technologies required to meet emerging challenges.

Obtain RF intelligence, maintain spectrum awareness, and achieve mission-critical objectives.

Radio receivers are essential for spectrum monitoring operations. Therefore, an understanding of receivers' key radio parameters and minimum recommended values allows spectrum managers to select the best radio receiver for their spectrum monitoring solution.

This white paper addresses the basic operating principles of 3D TDoA; Practical limitations on its accuracy; Applications of the technique.

Transportable direction finding system combining broadband monitoring and DF on wideband signals to 8 GHz.

This white paper outlines the various forms of AoA , including how they work, how they can be applied in practice, and how they can be combined with other geolocation techniques, such as time difference of arrival (TDoA).

This white paper explores how to enhance standard geolocation techniques such as AoA (Angle of Arrival), TDoA (Time Difference of Arrival), and PoA (Power on Arrival) by using the advanced signal processing methods employed by RFeye software and hardware. 

This white paper outlines the most important geolocation techniques, explains the differences between them, and provides an outline of their applications.
