This book provides an overview of the latest R&D advancements in the field of ICT technologies inherent to a New Space vision. The book presents a system-level and technology-level description of future space networking and communications. The authors also expand the vision to interplanetary networks. The book spans hardware and software technologies for future space communication networks, also considering very modern paradigms like quantum technologies and Softwarization. In the book, the word “space� is intended in a wider sense than the usual “satellite communications�, including new and partially unexplored fields like quantum space communications, interplanetary communications, and extra-terrestrial Radio Access Networks (RANs). The book includes applications including Internet of Space Things, Tactile Internet/Digital twins for Space and discusses future challenges like those involved by the concept of “sustainable Space�. Provides an overview of the latest R&D advancements in the field of ICT technologies inherent to a New Space vision; Considers visions and perspectives of space technology, including a through overview of satellite communications; Presents a system-level overview of future space networking and communications.

This book constitutes the thoroughly refereed post-conference proceedings of the Third International ICST Conference on Personal Satellite Services, PSATS 2011, held in Malaga, Spain, in February 2011. The 33 revised full papers presented were carefully reviewed and selected and cover a wide range of topics such as multimedia IP, next generation satellite networks, bandwidth allocation, aeronautic communications for air traffic management, DVB-S2, hybrid networks, delay tolerant networking, channel estimation and interference management, satellite antenna design, and localization systems.

This book constitutes the refereed proceedings of the 4th International Workshop on Multiple Access Communications, MACOM 2011, held in Trento, Italy, in September 2011. The 21 full papers presented were carefully reviewed and selected from more than 40 submissions. They are divided in topical sections on cognitive radio; MAC protocols; communications theory; special session on MAC protocols for WSNs; system analysis and scheduling; and queuing systems.
