Announcements

The MOSA Alliance is pleased to announce the release of two new products, designed to advance interoperability and drive innovation in space missions. Here is what is new:

ISTO GUIDE MOSA-IF-T-001: Tailoring for SDA-9100-001-09, Space Development Agency (SDA) Optical Communication Terminal (OCT) Standard Version 4.0.0

This guide focuses on the physical layer and data link layer for space-to-space optical communication networks.  Its primary goal is to enable interoperability between LEO space to space optical communication terminals, creating a strong foundation for reliable communication in space.

ISTO STD MOSA-IF-S-005: Payload to Launch Vehicle Interface Standard for NSSL-Class Missions (Volume 1: Mechanical Interfaces)

This standard enhances the National Security Space Launch (NSSL) Standard Interface Specification (SIS) by introducing greater mechanical interface standardization. It offers an efficient alternative to existing SIS mechanical requirements, enabling faster integration and helping compliant payloads meet tight, mission-critical timelines.

These new MOSA products are paving the way for more efficient, reliable, and standardized space systems. Dive in, explore, and join us in shaping the future of space exploration!

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 (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.

Committees

The objective of the Space Systems MOSA Interface Alliance is to have multiple committees/subcommittees developing interface standards across all segments of space systems.  The Alliance will target a subset of interfaces within and across the Space, Ground, Launch, and User segments.
