Spectra Group completes latest round of successful GENSS trials

Introduction to GENSS

Spectra Group, a specialist provider of secure voice, data and satellite communications systems, has announced for DSEi 25, the successful completion of their latest user trials for their next generation tactical radio GENSS.  The concept for GENSS was announced last year and since then Spectra Group has successfully completed full product development and now field testing with select user groups.  Spectra Group will be showcasing GENSS (pronounced genesis /jĕn′ĭ-sĭs), their award-winning tactical satellite SlingShot system and their recent addition to the Troposcatter Family of Systems, Troposcatter on the Move (TOTM), at DSEi, Excel, London (9-12 September 2025) at stand N2-430.

Evolution from SlingShot to GENSS

GENSS builds on the foundations created by the award-winning SlingShot system, embodying Spectra Group’s vision of producing ultimate radio systems that capitalise on technological advances, adapt to the evolving demands of military operations and simplify the user experience.

Collaboration with UK experts and military specialists

It has been designed and developed through a collaborative effort of tactical communication experts, seasoned military specialists and top-tier U.K. scientists and engineers. GENSS is a significant advancement in the field of tactical radio communications, due to its modular core framework and software-defined flexibility, heralding a new era in communication technology and along with the other Spectra Group products delivers a robust layered communications network to support mission critical headquarters and un-crewed systems over the horizon.

Latest Trials and Results

These latest field trials further validated the success and user benefits of GENSS, delivering a single tactical radio capable of meeting the extensive secure data, voice and application demands of modern military users.

Proven interoperability and modular design

GENSS is a modular, hardware-agnostic radio system designed and now proven to be exceptionally agile, providing ultimate interoperability through straightforward software reprogramming allowing it to adapt quickly and easily to diverse user needs.

Backwards compatibility and satellite integration

GENSS is backwards compatible with SlingShot and has the benefit it will automatically tune to the L-TAC frequency, converting any military or civilian HF, VHF or UHF FM radio into a mobile global satellite communications system.

Advanced Capabilities of GENSS

Multi-mode and multi-mission flexibility

GENSS is also a multi-mode and multi-mission software defined radio in its own right, designed for agility and interoperability whilst focusing on cognitive simplicity for the operator.

ATAK integration and MANET bridging

As well as a bespoke radio firmware package, Spectra Group has developed an integrated software data management package that allows Beyond Line of Sight (BLOS) bridging capability for closed/remoted MANET networks. Integrating and managing MANET data feeds into ATAK mission software, Spectra has ensured that wide band mission critical data, such as Personal Location Information (PLI) and Cursor on Target (CoT), can be transmitted over narrowband L-TAC channels, with recent trials also proving streaming video over L-TAC services is possible.

Secure and resilient BLOS communications

By maximising the capability and flexibility that L-TAC offers, GENSS overcomes all traditional BLOS barriers and delivers true Communications on the Move (COTM) for individuals and platforms and by design has a low probability of detection or interception, enhancing its security and operational effectiveness. GENSS is therefore a robust and agile solution for voice and data transmission across all domains and platforms, whether on land, sea or in the air.

Leadership Perspective

Simon Davies on GENSS development

Simon Davies, Chief Executive at Spectra Group said,

“As a veteran led organisation, my mission has been to craft the ultimate radio system — user-friendly, light, modular and supremely flexible to adapt to the evolving demands of military operations and technological advances. I am immensely proud and excited of what the GENSS team have managed to achieve, and these trials represent the pinnacle of our collective efforts to provide the user with simple and effective solutions. With this latest round of trials, and the rigorous process of full military specification certification to 801/461G complete, we remain on track to bring GENSS to market in the very near future.”
