What is the SOSA Technical Standard?

The SOSA Technical Standard defines a common framework for transitioning sensor systems to an open systems architecture. The SOSA standard leverages OpenVPX to define card profiles with specifications for features such as pinouts, Ethernet capabilities, and serial ports.

Exploring SOSA, CMOSS, FACE, VICTORY, and More

This white paper examines the 2019 tri-services memo regarding MOSA, and what open standards such as SOSA, FACE, and VICTORY mean for today’s military programs.

Proven Solutions Aligned to the SOSA™ Technical Standard

Curtiss-Wright is committed to delivering the broadest selection of reliable, high-performance hardware developed in alignment with The Open Group SOSA Technical Standard. We are an active participant in the development of the SOSA Technical Standard itself through our membership in the SOSA Consortium, ensuring our products will be ready to meet future requirements, alleviate interoperability challenges, and deliver a variety of benefits to mission-critical C5ISR systems.

Our innovative plug-in cards (PICs) designed to meet SOSA program requirements provide the hardware foundation for next-generation defense capabilities, like machine learning and artificial intelligence (AI). And our system integration experts are ready to provide the expertise, services, and chassis options to bring your system to market even faster.

Common Hardware and Software Components for Sensor Processing Systems

The SOSA Technical Standard defines a common framework for transitioning sensor systems to an open systems architecture. The SOSA standard leverages OpenVPX to define card profiles with specifications for features such as pinouts, Ethernet capabilities, and serial ports.

Rugged, deployable systems developed to Modular Open Systems Approach (MOSA) standards are becoming increasingly important in the defense industry. The U.S. military’s 2019 Tri-Services memo, signed by the Secretaries of the Army, Air Force, and Navy, has even explicitly mandated 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.

The MOSA directive has accelerated the adoption of several open standards, including The Open Group Sensor Open Systems Architecture™ (SOSA) Technical Standard and the U.S. Army CCDC C5ISR Center’s C5ISR/EW Modular Open Suite of Standards (CMOSS). Complementing industry standards, such as OpenVPX™ and Future Airborne Capability Environment (FACE™), the SOSA Technical Standard defines common hardware and software components for sensor processing systems.


The MOSA Imperative

This Curtiss-Wright Position Paper aims to put MOSA (Modular Open Systems Approach) into perspective and enable you, whether a defense contractor, a decision-maker at the DoD, or a public policymaker, to put the increasingly relevant MOSA to use better. MOSA drives faster time to market, lower cost, increased software portability, technology innovation, and interoperability among systems across all defense domains. This Position Paper will guide you through why MOSA exists, its history and context, and why MOSA is ideally suited to creating the capabilities required to counter an uncertain and dangerous world of rapidly shifting threats.
