UK ENGINEERING PROVIDING ASSURED CONNECTIVITY

Spectra Group designs, engineers and delivers communications systems and services for defence and security organisations. We support all elements of the Communications PACE plan – Primary, Alternate, Contingency and Emergency – to help users maintain assured connectivity in demanding operational environments.

Drawing on decades of military communications experience and UK engineering expertise, we help dispersed formations maintain voice and data connectivity where distance, terrain and limited infrastructure constrain communications, including in denied, disrupted, intermittent and limited (DDIL) conditions.

Built on an established heritage that includes the award-winning SlingShot, our capabilities span Evergreen software-defined tactical communications, range extension for in-service tactical radios, high-capacity over-the-horizon connectivity and optical communications.

Our experience extends from system development and integration to delivery and ongoing support for operational users.

Our Communications Capabilities

GENSS™

Evergreen Software-Defined Tactical Communications

An Evergreen software-defined tactical communications system enabling secure satellite networking, MANET extension and efficient beyond-line-of-sight voice and data connectivity for distributed forces. Its architecture is designed to support capability evolution as operational requirements and technologies change.

SlingShot®

Range Extension for In-Service Tactical Radios

SlingShot gives existing tactical radios access to L-Band satellite communications, extending voice and data connectivity beyond line of sight while allowing forces to continue using familiar equipment.

Troposcatter

High-Capacity OTH Connectivity

Troposcatter systems provide high-capacity, low-latency data links beyond the horizon without relying on satellites or chains of terrestrial repeaters. Deployable and mobile options help sustain connectivity where fixed infrastructure is unavailable or degraded.

EOS

High-Capacity Optical Connectivity. No RF Signature.

EOS uses narrow, invisible beams of light to provide high-capacity point-to-point connectivity. It adds a rapidly deployable transmission path outside the RF spectrum, supporting network resilience where line of sight and local conditions permit.

Communications Across Operational Environments

Spectra Group develops communications systems that connect distributed forces, extend operational reach and support the movement of mission data. Our engineering-led approach integrates complementary capabilities to meet operational requirements and strengthen network resilience.

Connecting Dispersed Forces

Reliable voice and data connectivity for personnel operating across dispersed locations and demanding environments, supporting interoperability with coalition forces.

Extending Communications Reach

Maintaining connectivity beyond terrestrial line-of-sight limitations through satellite and other beyond-line-of-sight communications systems.

Supporting Data-Intensive Operations

High-capacity communications for moving operational data between deployed locations and network infrastructure.

Strengthening Network Resilience

Complementary communications bearers support the Communications PACE plan, providing alternative connectivity paths in denied, disrupted, intermittent and limited (DDIL) environments.
