The 955 Rackmount RF COMINT and Geolocation System and the 957 Rackmount RF COMINT and Independent Geolocation System will be shown for the first time at DSEI 2025, 9th–12th September, ExCeL London.
The systems deliver rapid detection, filtering, and geolocation of RF communication signals across congested spectrum environments, enabling faster decision-making and reaction times, improved threat awareness, and greater operational agility. Their 80 MHz Instantaneous Bandwidth – double that of its predecessor – allows wide-area signal collection for broad situational awareness, or narrower focus for heightened sensitivity in challenging RF conditions.
Combining two geolocation techniques – Hybrid Angle of Arrival (AOA) and Time Difference of Arrival (TDOA) – enables precise signal location with fewer deployed assets, even over low-bandwidth or intermittent networks.
The rugged, rack-mounted design supports deployment in vehicles, fixed installations, or forward field positions. Both models are built for mission flexibility, with the ability to switch roles without reconfiguration, from counter-terrorism and border security to front-line combat. The 955 is optimised for single-unit, vehicle-mounted, or stand-alone operations, while the 957 offers enhanced processing capacity for simultaneous, independent tasking and networked multisensor geolocation across dispersed teams.
The RF systems also feature a 72-hour look-back recording capability, enabling operators to identify a new threat and immediately analyse historical spectrum activity to extract further intelligence. The feature also supports automated and remote monitoring options, reduces manpower requirements for persistent 24/7 operations and lowers operational costs. A database allows further intelligence analysis for days, weeks and months.
Both systems operate using TCI’s Blackbird software, currently in operational use on almost 1,000 frontline systems worldwide. Blackbird provides an intuitive interface that reduces training time and enables less experienced operators to perform effective COMINT tasks, immediately expanding the possible pool of operators. It allows highly skilled personnel to remain in safer, decentralised positions while remotely managing deployed systems, multiplying force effectiveness.
Built on the combat-proven heritage of their predecessor, the 953 receiver, the new 955 and 957 are backwards compatible with existing SPX Communication Technologies and partner systems, including the ECS BLACKTALON counter-uncrewed aerial system (C-UAS) solution, for scalable integration into wider electronic warfare architectures.
“Today, electronic warfare is at the heart of all defence operations, and mastering the spectrum is now as critical as controlling the air,” says David Beckett, Battlespace Business Development Director at TCI. “Our new systems give defence teams the decisive intelligence they need to succeed.”
