MSS Reference Architecture
Version 1.0 – More Chapters to Come!
Executive Summary
As satellite communications advance, Non-Terrestrial Network (NTN) systems are increasingly vital to extending connectivity to remote and underserved regions, while complementing terrestrial networks. The Mobile Satellite Services Association’s Reference Architecture document offers strategic recommendations to accelerate the development, deployment, and global integration of NTN technologies.
This 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:
- Technological advancements for satellite constellations, ground infrastructure, and mobile devices
- Guidelines for interoperability with terrestrial networks
- Prioritized use cases such as resource management, network selection, roaming, and network sharing
- Insights into delivering messaging, voice, data, and IoT services via NTN technologies
