Description
Book SynopsisPresents the concepts, technology, and role of satellite systems in support of personal applications, such as mobile and broadband communications, navigation, television, radio and multimedia broadcasting, safety of life services, etc. This book presents a novel perspective on satellite systems, reflecting the modern personal technology context, and hence a focus on the individual as end-user. The book begins by outlining key generic concepts before discussing techniques adopted in particular application areas; next, it exemplifies these techniques through discussion of state-of-art current and emerging satellite systems. The book concludes by contemplating the likely evolution of these systems, taking into consideration influences and trends in technology, in conjunction with growing user expectations.
In addition to addressing satellite systems that directly interact with personal devices, the book additionally considers those indirect applications where there is an
Trade Review
"Thorough, thoughtfully presented, and well illustrated, this textbook presents the world of satellite technology now prevalent in everyday life, using the individual, end-user application as its organizing principle." (Booknews, 1 February 2011)
