ENGINEERING FREEDOMFOR THE FUTURE FORCE
OPEN SYSTEMS ARCHITECTURE
Building adaptable, interoperable systems that evolve with demanding requirements and accelerate capability across every domain.
As platforms become more complex and technology cycles accelerate, organizations must field systems that can upgrade faster, integrate easier, and remain relevant longer. Proprietary architectures slow modernization, increase lifecycle costs, and restrict the ability to introduce new technology at speed.
Open Systems Architecture (OSA) changes this dynamic by delivering modular, interoperable, vendor-neutral designs that allow programs to integrate emerging capabilities without rebuilding the system around them. With OSA and Modular Opens Systems Approach (MOSA) principles in place, organizations gain flexibility, reduce risk, and ensure their platforms remain operationally-ready over decades, not years.
The Precise Difference
Precise Systems applies Open Systems Architecture to enable scalable, adaptable, and affordable systems across aviation, maritime, land, for crewed and uncrewed platforms. Our teams have more than two decade of experience shaping OSA approaches across U.S. and international defense initiatives, including work with NATO and key allied partners.
By pairing deep technical expertise with a strong understanding of operational, acquisition and lifecycle demands, we help customers implement architectures that are modular, standards-compliant, and built for rapid integration. Whether modernizing legacy systems or engineering new ones, we ensure architectures remain flexible enough to support the technology of today, and the innovations that will define tomorrow.
Enabling Rapid Advancement with Open Systems Architecture
Open Systems Architecture provides a framework for building systems that are interoperable, modular, and designed to evolve. By relying on open standards and clearly defined interfaces, OSA enables components to integrate seamlessly, scale predictably, and be upgraded or replaced without disrupting the broader system. This approach reduces dependency, accelerates technology insertion, and preserves architectural flexibility over time, ensuring systems remain adaptable, portable, and relevant as requirements and technologies change.
Interoperability
Open, standards-based interfaces allow systems and subsystems to work together without custom integrations. OSA improves compatibility across platforms, services, and allied partners, reducing integration time and supporting coordinated operations.
Portability
By separating software from hardware dependencies, OSA makes capabilities easier to reuse or migrate across platforms. Standardized interfaces and runtime environments minimize redevelopment effort and accelerate fielding of proven solutions.
Modularity
OSA structures systems into well-defined modules that can be developed, upgraded, or replaced independently. This reduces risk, supports parallel development, and enables faster insertion of new technology.
Scalability
Open architectures support system growth without major rework. Whether adding processing capacity or integrating new subsystems, OSA keeps upgrades stable, predictable, and cost-effective across a platform’s lifecycle.
Extensibility
With clear extension points and open standards, OSA enables new capabilities to be added as needs evolve. This ensures systems remain adaptable, relevant, and aligned with emerging technologies.
