Announcements
The ISTO Space Systems MOSA Interface Standards Alliance (AKA, MOSA Alliance) is pleased to announce the instantiation of a new committee for MBSE Modeling Standards. This committee will develop standards that will enable interoperability across MBSE models. Interoperability across MBSE models will allow greater assessment fidelity for the identification of future Enterprise capability needs, gaps, and technology onramp opportunities. Current MBSE models lack sufficient standardization, even when using the same modeling tools and language, to support the ability to string together models of different systems from different companies to visualize (via simulations) and optimize the utility of the different systems toward Enterprise mission objectives. The ISTO MOSA Alliance’s MBSE Modeling Standards committee will provide the first steps in the incremental and evolutionary advancement of interoperable MBSE system models.
The MOSA Alliance is seeking interested subject matter experts with the appropriate expertise to actively participate in driving accelerated development of Standards using an agile approach of minimum viable product deliveries in six-month sprints. MBSE Modeling Standards are needed as soon as possible to start driving the development or revision of models that will help us more effectively coordinate and interoperate with a variety of key space resources.

Who we are
The Space Systems MOSA Interface Standards Alliance is interested in rapidly developing modular open system approach (MOSA) compliant space system standards that will enable interoperability at key system interfaces. Collaborating with the Institute of Electrical and Electronics Engineers Industry Standards and Technology Organization (IEEE-ISTO) will enable the Space Systems MOSA Interface Standards Alliance to leverage agile development methods to expedite the standards development process.
The Space Systems MOSA Interface Standards Alliance is a government-guided collaboration with industry for the purpose of voluntary consensus development of space system interface standards, in accordance with Public Law 104-113, and OMB Circular A-119. Furthermore, in accordance with the MOSA laws specified in the 2015/2017/2022/2021 National Defense Authorization Acts (NDAA), the space system interface specifications will enable and foster interoperability at key system interfaces

What We Do

The Space Systems MOSA Interface Standards Alliance consists of committees and subcommittees developing interoperability standards that meet Enterprise-defined objectives. The collection of standards developed by the alliance will synergistically support Enterprise objectives. By creating standardized interfaces, the Enterprise seeks to benefit from a wider range of industry innovations and bring newer technologies to our warfighters faster. Standardization will also enable and foster the ability of non-traditional companies to enter the established market.
