4.1 Innovative architecture design

XOS adopts the U.S. military standard open architecture. It is able to flexibly expand and adapt to the needs of various scenarios, and at the same time ensures the stability and reliability of the system.

It is rare to have brand new technology innovation starting from scratch. Most innovations nowadays are cross-field.

Components of an open architecture

The open system architecture is primarily based on the guiding principles of Modular Open Systems Architecture (MOSA) that is implemented at both business and technical levels. On the business side, it focuses on unified procurement models and control over intellectual property rights for both new and existing technologies. On the technical side, it follows the design principles of MOSA and employs a modular design pattern to separate systems, subsystems, and components. This establishes an open system architecture with standardized modular interfaces and consensus standards across various domains. Additionally, all software and hardware integrations undergo uniformity certification to ensure the generality, reusability, upgradeability, configurability, and other attributes of each module. The diagram above illustrates the relationships between these concepts, with OSA serving as a general term for numerous open system architectures.

Background of MOSA

In the 1990s, the U.S. Department of Defense introduced the Modular Open Systems Approach (MOSA) as a strategic standardization plan. This initiative aimed to ensure the efficient operation of the thousands of products and systems procured annually by the military services. MOSA represents a significant guiding principle for military equipment development, utilizing modular design to maximize equipment interoperability across heterogeneous and cross-generational platforms.
