Onyx Spectrum Legacy Solutions (OSLS) is the Division of Onyx Spectrum Technology,

providing long-term support and sustainment for embedded legacy products critical to long- lasting applications in the defense, government, utility and OEM sectors for Embedded

Electronics, Signal Processing Electronics and Systems, Electro-Optical Systems and Communications Systems, addressing both Legacy Support and Legacy Sustaining issues.

Sustaining Engineering is crucial to end-user organizations with reliance on or planning transitioning from manufacturer discontinued products, or where the manufacturer is no longer in business and there is a need to extend the life and capabilities of the installed systems that are part of the end-user’s critical infrastructure and there is no ongoing support for the systems.

Sustaining engineering is also an increasingly competitive advantage for OEM companies providing commercial off-the-shelf (COTS) technology. With extending the life of existing products gaining focus, a robust sustaining engineering strategy increases product lifespan by multiple years. Moreover, it helps to ensure that the product addresses the market needs, is compliant, cost-effective and can support a planned approach to transitioning to newer equipment.
