GENSS – Future-Ready Tactical Communications | Spectra Group
GENSS
Built by users, engineered in the UK, trusted for the fight ahead.
The revolutionary next-gen communications system designed to evolve with you.
GENSS is a future-ready secure communications platform built for users who need agility, adaptability and absolute confidence in contested environments. Designed by former military operators and engineered in the UK, it delivers intelligent efficiency, robust security, and a modular core able to grow with every mission.
Future-ready, by design
GENSS is a new breed of secure, software-defined communications platform — built for operational independence and designed to adapt as fast as the mission.
Developed by leading UK engineers and created by former Specialist users, GENSS delivers an agile, modular architecture that gives you voice and data dominance wherever you operate — on the move, on the soldier, or on the platform.
Built in the UK | Designed by users for users | Trusted innovation from Spectra Group
Confidently secure comms
Operate with confidence, even in the most contested and congested environments.
GENSS uses Low Probability of Intercept/Detection (LPI-D) technology, AES-256 encryption, and anti-tamper design to “hide in the noise” — ensuring mission-critical voice and data remain protected.
Communications on-the-move are maintained through adaptive waveforms that continually optimise performance in changing conditions.
Adaptable and future-ready
GENSS is built around an open, modular core — a scalable platform ready to evolve with technology, policy, and mission demands.
Whether integrated into UAVs, UGVs, sensors, or soldier systems, its architecture allows interoperability across HF, VHF, UHF, and satellite bands from 29 MHz to 6 GHz — giving you the freedom to build, deploy, and expand without limits.
Highlights:
- Common core radio module
- Open API for easy integration (TAK-ready)
- Multiple form factors for diverse mission sets
- Future software and waveform upgrades
Intelligent Efficiency
GENSS is designed to optimise performance even in degraded, congested or EW-threatened environments.
Its precision-engineered MODCOD and spectral efficiency enable high throughput with minimal bandwidth, including best-in-class L-TAC performance.
Performance proof points:
- Up to 90 kbps on a standard 25 kHz L-TAC channel
- Data-throughput down to 4.8 kbps @ 0 dB SNR
- Adaptive and autonomous modulation & coding
- Optimal performance with low power output
- True BLOS capability with both radio and satellite channels
Built for Agility
GENSS is designed for the user—intuitive, lightweight, quick to deploy and easy to operate under pressure.
Its SWaP-optimised design reduces the cognitive and physical burden on operators while enabling rapid changes between modes without complex field programming.
User-centred benefits:
- Lightweight, compact and power-efficient
- Minimal training requirement
- Intuitive menu and mission-mode switching
- Rapid integration into soldier systems
- Seamless transition between voice and data
