A spacecraft is a complex system which involves the integration of both hardware and software. It requires different IoT architectures with sensors, networks and applications, and many others for information modelling, simulation, optimization and decision support methods and techniques. IoT and Spacecraft Informatics provides the theory and applications of IoT systems in the design, development and operation of spacecraft. This book presents a high-level overview of IoT and introduces key concepts needed to successfully design IoT solutions, key technologies, protocols, and technical building blocks that combine into complete IoT solutions. The book features the latest advances, findings and state-of-the-art in research, case studies, development and implementation of IoT technologies for spacecraft and space systems. It also concentrates on the different aspects and techniques to achieve automatic control of spacecraft. This book is for researchers, PhD students, engineers and specialists in aerospace engineering as well a those in computer science, computer engineering, or mechatronics interested in both of space engineering and IoT.
