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 the resilient backbone for assured connectivity — empowering faster decisions and safer operations.


GENSS™ — Adaptive Connectivity for the Decisive Edge

Future-Ready Tactical Communications

Developed by Spectra with leading UK technologists, GENSS™ is a revolutionary tactical radio platform that delivers secure, low-probability-of-intercept communications beyond line of sight.

With adaptive modulation, open architecture, and modular form factors, GENSS™ connects dismounted, vehicle and command users through a single resilient network — providing simultaneous voice and data, higher throughput, and reduced operator burden.

Key Capabilities

  • Future-Ready – Modular, software-defined and interoperable with leading mission systems.
  • 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 connectivity 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.
