San Ramon, Calif. — November 19, 2025 — The Mobile Satellite Services Association (MSSA) is proud to announce the release of its Reference Architecture document, offering strategic recommendations to accelerate the development, deployment, and global integration of open and interoperable Non-Terrestrial Network (NTN) solutions.
As satellite communications advance, NTN systems are increasingly vital to extending connectivity to remote and underserved regions, while complementing terrestrial networks. MSSA’s Reference Architecture emphasizes the importance of system-level design to ensure consistent device performance and seamless user experiences.
Developed by the MSSA Technical Committee’s Reference Architecture Work Group, the document addresses key challenges and outlines best practices across the entire service delivery chain, from satellite constellations and ground infrastructure to mobile devices, to meet growing demands for high-speed, reliable, and secure connectivity.
Key Focus Areas Include:
“This Reference Architecture is a major step forward in shaping a cohesive and interoperable NTN ecosystem,” said Jeff Snyder, MSSA Reference Architecture Work Group Lead and Chief Technology Officer at MSSA member Omnispace. “By aligning with 3GPP specifications and addressing real-world use cases, our recommendations aim to guide industry stakeholders toward scalable, secure, and high-performance NTN solutions.”
The document also supports ongoing standardization efforts led by global bodies such as 3GPP and GSMA, reinforcing MSSA’s commitment to fostering innovation and industry-wide collaboration.
Future versions of the Reference Architecture will explore emerging topics and provide deeper insights into areas introduced in this first release. MSSA invites interested stakeholders to become members and participate in its technical committees, collaborating to solve key challenges and shape the future of NTN technologies.
