The new edition of the book is made more attractive and useful with the incorporation of lots of figures, illustrations and examples. The compact text provides a thorough, readable treatment of the principles of satellite communication and its various technologies and components. It presents a clear analysis of subsystems of satellites, orbital mechanisms, launching mechanisms, earth and space systems employed in satellite links, analog and digital communication through satellite, multiple beam satellite network, and satellite telephony. It is going to become an important subject also in Civil Engineering for the purpose of disaster management. Therefore, in the last chapter, recent developments and future trends in satellite systems are discussed adequately. Besides, it explains the different methods used to access the various services provided by a satellite. The text avoids complicated mathematical derivations, but the results of these derivations and their references are used throughout the book when required for understanding the technical concepts. This easy-to-understand textbook is primarily intended as a textbook for undergraduate students of electronics and communication engineering, telecommunication engineering, and information technology.
