This book delves into the burgeoning field of space-ground integrated networks (SGINs), focusing on the evolution, architecture and application scenarios of large satellite constellations. As global communication demands surge, the next-generation SGINs are transitioning towards large-scale, hyperscale, and hierarchical constellations to address diverse user needs, such as ultra-long-haul, high-speed and instantaneous communications. Through an in-depth exploration of network working principles, traffic and link modeling, and performance analysis and optimization methods, this book offers substantial guidance to readers. It aims to uncover pathways for enhancing network service capability and to establish a solid theoretical foundation for the future development of mega-satellite constellations within the SGIN framework.



Furthermore, this book provides a comprehensive analysis of SGINs, examining its network architecture, developmental trajectory and application scenarios. It delves into the core challenges faced by SGINs and proposes response strategies. This book introduces various methods for service capability modeling and quantitative performance analysis across different traffic types, emphasizing the intricate relationships between network performance, traffic patterns, nodes, links and network characteristics. Through an exhaustive study of large-scale satellite network operations, this book illuminates avenues for improving network service capacity, thereby paving the way for theoretical guidance and technical support for future ultra-large-scale SGINs. By offering systematic analyses and insights, this book aims to equip readers with a profound understanding and practical guidance for SGIN network planning and optimization. It also highlights future trends and potential application scenarios in the evolving landscape of network technology.



This book targets advanced level students, professors, researchers and scientists working in the fields of telecommunications, satellite communications and network engineering, who wish to gain an in-depth understanding of SGIN principles, performance analysis and optimization techniques. Practitioners working in aerospace or telecommunications policy making to gain insights into future trends and challenges in satellite network design and optimization will want to purchase this book as well.
