Mission-Critical Communications for the Modern Battlespace

Spectra Group designs and delivers mission-ready communication systems that ensure decision advantage in any environment. Built by experienced operators and engineers, our solutions give users the freedom to move, communicate, and command — securely, reliably and without dependency on vulnerable infrastructure.

From small teams on the move to multi-domain task forces, Spectra’s systems provide resilient communications capability for distributed forces, empowering faster decisions and safer operations.

GENSS™ Evergreen Tactical Communications

Built to Endure. Engineered to Adapt.

Developed by Spectra with leading UK technologists, GENSS™ is an Evergreen software-defined tactical communications system delivering secure beyond-line-of-sight voice and data communications for distributed forces.

Designed for distributed and mobile operations, GENSS enables secure voice and data communications beyond line of sight while extending tactical MANET networks beyond the traditional line-of-sight “bubble”.

Built around a scalable, modular SDR architecture, the system supports adaptable waveform development, ATAK interoperability, and efficient operation across contested and degraded environments.

Key Capabilities

Evergreen Architecture – Modular, software-defined and designed to evolve as operational requirements change.
Secure – AES-256 encryption and “hide-in-the-noise” resilience against detection or exploitation.
Lightweight & Intuitive – SWaP-optimised and designed by ex-operators for ease under pressure.

Troposcatter Systems

Reliable, High-Throughput Links Anywhere

Spectra’s Troposcatter systems— including COMET, TOTM (Troposcatter On-The-Move), and MTTS — deliver assured communications where infrastructure is lacking, unreliable, or has failed.

Proven in international trials and field deployments, these systems achieve exceptional data rates at minimal power, providing sovereign, high-capacity communications for expeditionary, maritime, and autonomous operations.

Key Capabilities

High Capacity – Up to 210 Mbps over distances of up to 250km (depending on conditions).
Contested-Environment Resilience – Maintains connectivity under jamming and EW pressure.
Scalable Mobility – From on-the-move to modular transportable configurations.
