What System Designers Should Know About MOSA Standards

Published in Aerospace & Defense Technology

In today’s technology-rich battlefield, new threats emerge and change quickly. Rapidly responding to new threats in this dynamic environment is one of the primary drivers behind the DoD mandate to adopt a Modular Open Systems Approach (MOSA) for procurement across the Army, Air Force, and Navy. The MOSA mandate drives a modular approach to system design that lowers the cost of integration and speeds the deployment of new capabilities to address emerging threats.

The MOSA directive has greatly accelerated the adoption of open system standards, such as the U.S. Army CCDC C5ISR Center’s Army’s Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) Modular Open Suite of Standards (CMOSS) and the Sensor Open Systems Architecture (SOSA) Technical Standard, supported by the Tri-Services and led by The Open Group’s SOSA Consortium. Defense system integrators need to understand the MOSA mandate and become familiar with leading MOSA-aligned standards, such as CMOSS and SOSA, before developing system solutions.

Your Essential Guide to MOSA

Introducing your essential guide to all things MOSA. This white paper explores the MOSA directive, its significance for defense technology, and MOSA-supporting standards like SOSA, CMOSS, VICTORY, GVA, FACE, and OMS/UCI.

What is the Modular Open Systems Approach (MOSA) Directive?

On January 7, 2019, the U.S. Department of Defense (DoD) issued a memo, signed by the Secretaries of the Army, Air Force, and Navy, mandating the use of the Modular Open Systems Approach (MOSA). The memo states that “MOSA supporting standards should be included in all requirements, programming and development activities for future weapon system modifications and new start development programs to the maximum extent possible.”
