The U.K. Ministry of Defence’s approach to mandate open, modular, and scalable architectures in the design of land vehicles

GVA’s standards apply to electronic and power infrastructures, mechanical interfaces, Human Machine Interfaces (HMI) and Health and Usage Monitoring Systems (HUMS). Outlined in Ministry of Defence Standard (Def Stan) 2309, the goal of the GVA approach is to realize operational, technical, and cost benefits by promoting open standards for software and hardware interfaces to enable simple and rapid replacements or upgrades of equipment as needed.

Applied to both new and upgrade land vehicle designs, the GVA infrastructure encourages the use of scalable, modular, open systems based, adapters or gateways to enable interoperability with legacy equipment. Similar to VICTORY, GVA does not mandate specific solutions but specifies a generic architecture that is platform and vendor agnostic, which can be tailored to design requirements. Interoperability is enabled by the Data Distribution Service (DDS) middleware system, a generic software interface that allows the exchange of data between equipment of different manufacturers.

GVA ready solutions help combat obsolescence, and enable an upgrade path that speeds and eases the addition of new capabilities to vehicles in the future. Using a GVA ready multi-function crew display and control unit enables the integration of multiple electronic subsystems while reducing cabling weight and clutter.

At the frontline of bringing GVA architecture into ground vehicles, rugged COTS technologies from Curtiss-Wright are helping to showcase the benefits of adopting a common communications architecture and consolidating modern computing and networking architectures for SWaP optimization.

Leveraging over 80 years of experience and expertise developing rugged, field-proven defense technology, Curtiss-Wright has engineered its GVA ready solutions to not only optimize SWaP, flexibility, and modularity in ground vehicle systems, but also ensure scalability and interoperability with legacy systems. Beyond providing these benefits to ground vehicle designers and the armies they provide for, these open standards-based solutions improve the in-vehicle experience for today’s warfighters. By reducing system complexity and clutter while enhancing situational awareness, Curtiss-Wright solutions like the DBH-670 and DBH-672 switch router and GVDU Mission Display provide the performance and reliability ground vehicle operators can trust to protect them as they protect our nations.
