Presents the concepts, technology, and role of satellite systemsin support of personal applications, such as mobile and broadbandcommunications, navigation, television, radio and multimediabroadcasting, safety of life services, etc.
This book presents a novel perspective on satellite systems,reflecting the modern personal technology context, and hence afocus on the individual as end-user. The book begins by outliningkey generic concepts before discussing techniques adopted inparticular application areas; next, it exemplifies these techniquesthrough discussion of state-of-art current and emerging satellitesystems. The book concludes by contemplating the likely evolutionof these systems, taking into consideration influences and trendsin technology, in conjunction with growing user expectations.
In addition to addressing satellite systems that directlyinteract with personal devices, the book additionally considersthose indirect applications where there is an increasing interestby individuals - notably, in remote sensing. As such, the bookuniquely encompasses the entire gamut of satellite-enabled personal/ end-user applications.
Key Features:
* Broad scope - views satellite systems generically with regardsto their applicability across a wide range of personal applicationareas
* Strong foundation in underlying concepts
* State-of-the-art system examples
* Review of trends in relevant areas of satellite technology
* Revision questions at the end of each chapter
The book is suited to individuals, engineers, scientists,service providers, system operators, application developers andmanagers interested or involved in the use of satellite technologyfor personal applications. It should also hold interest for use inresearch institutes interested in promoting inter-disciplinarycross-fertilization of ideas, as well as by financiers, policymakers, and strategists interested in gaining a betterunderstanding of this technology.
