At AOC Europe 2026, CRFS is participating alongside Silvus Technologies, presenting a range of technologies focused on passive RF sensing, electronic warfare (EW), and multidomain operations. AOC Europe is one of Europe’s leading electronic warfare events taking place from 19–21 May at Messukeskus Helsinki.
The event comes at a time when modern military operations are placing increasing emphasis on the ability to monitor, interpret, and manage the electromagnetic spectrum. CRFS is demonstrating how its RFeye technology supports situational awareness and operational decision-making in contested environments.
Among the systems on display is the RFeye Ranger, an operator-portable RF sensing and geolocation platform designed for dismounted electronic support measures (ESM). The system covers frequencies from 9 kHz to 18 GHz and weighs less than 6.5 kg, enabling easier transport and deployment in field environments.
CRFS is also presenting its Aerial Monitoring System, which combines an ISR drone with an RF sensor payload to expand monitoring coverage across land, air, and maritime domains. According to the company, the system can be deployed in under eight minutes and supports variable-height monitoring up to 100 metres, extending radio horizon capabilities.
Another featured system at AOC Europe is the DFH40 Antenna, a compact direction-finding head operating across a frequency range of 500 MHz to 40 GHz. The antenna supports wideband spectrum monitoring, angle-of-arrival (AoA) direction finding, and both 2D and 3D time difference of arrival (TDoA) capabilities in a ruggedized tactical format.
The company is also demonstrating its Signal Discovery Software, developed to identify difficult-to-detect drone signals, as well as RF payload integration capabilities designed for unmanned platforms and command-and-control systems through open interfaces and APIs.
CRFS said its broader defense portfolio includes applications for air defense, border security monitoring, and direction-finding operations. Company representatives are available during the exhibition to discuss operational requirements ranging from coverage gap monitoring between fixed assets to persistent long-endurance surveillance missions.
