Supporting, maintaining, upgrading and replacing obsolete test systems.

For more than 70 years, we have been developing test systems for the UK’s mission and safety-critical sectors. Many of the systems we developed in the 1980s and 1990s are still in-service, kept alive by our knowledge of their architecture, usage and obsolescence issues and the technology that is available to replace them.

We provide a suite of services from ongoing support and maintenance contracts to upgrades, replacements and other life-extending solutions. We know how to bring new life to old systems without compromising on compliance and ensure that commercial sensitivities are managed through a careful balance of value for money and technical assurance.

We have developed a suite of tools that can be easily adapted to any legacy test system to allow for seamless integration of new hardware without compromising its functionality (and thus certification status).

Our People

All our programme managers have technical backgrounds. They are typically experienced hardware and software engineers with long-standing experience in the development of test systems. Selected for their ability to see the bigger picture as well as their communication and customer-facing skills, we provide them with regular project management training (PRINCE2 certified) to ensure they are consistently up to date with the latest industry requirements.
