Book Description
Every facet of satellite technology is included in this concise reference guide to a fast developing field. The latest systems are included and the coverage is worldwide. Supplemented with tables, formulae and footprints for satellites, this pocket book is the first place for communications engineers, students, satellite industry personnel and enthusiasts to look for essential data. DBS and other enabling technologies for HDTV are covered, in this wide-ranging review of technologies used in Europe, America, the Middle East and Asia. Drawing on James Wood's extensive experience as an engineer in the international broadcasting industry and a technical broadcast journalist, this book will provide the essential details of satellite communications.

Book Description
Satellites are increasingly used for global communications, as well as for radio and television transmissions. With the growth of mobile communications, and of digital technology, the use of satellite systems is set to expand substantially and already all students of electronics or communications engineering must study the subject. This book steers a middle path between offering a basic understanding of the process of communication by satellite and the methodology used; and the extensive mathematical analysis normally adopted in similar texts. It presents the basic concepts, using as much mathematical content as is necessary to make the process understandable. The principles introduced are backed up by examples of actual applications showing how professional systems engineers have achieved the required system performance capabilities. The practical systems chosen are representative of modern day applications and comprise an international communications system, an international maritime system and a regional system.

Book Description
This is the first book primarily about the satellite payload of satellite communications systems. It represents a unique combination of practical systems engineering and communications theory. It tells about the satellites in geostationary and low-earth orbits today, both the so-called bent-pipe payloads and the processing payloads. The on-orbit environment, mitigated by the spacecraft bus, is described. The payload units (e.g. antennas and amplifiers), as well as payload-integration elements (e.g. waveguide and switches) are discussed in regard to how they work, what they do to the signal, their technology, environment sensitivity, and specifications. At a higher level are discussions on the payload as an entity: architecture including redundancy; specifications--what they mean, how they relate to unit specifications, and how to verify; and specification-compliance analysis (“budgets”) with uncertainty. Aspects of probability theory handy for calculating and using uncertainty and variation are presented. The highest-level discussions, on the end-to-end communications system, start with a practical introduction to physical-layer communications theory. Atmospheric effects and interference on the communications link are described. A chapter gives an example of optimizing a multibeam payload via probabilistic analysis. Finally, practical tips on system simulation and emulation are provided. The carrier frequencies treated are 1 GHz and above. Familiarity with Fourier analysis will enhance understanding of some topics. References are provided throughout the book for readers who want to dig deeper. Payload systems engineers, payload proposal writers, satellite-communications systems designers and analysts, and satellite customers will find that the book cuts their learning time. Spacecraft-bus systems engineers, payload unit engineers, and spacecraft operators will gain insight into the overall system. Students in systems engineering, microwave engineering, communications theory, probability theory, and communications simulation and modelling will find examples to supplement theoretical texts.

Book Description
Over the past 40 years, satellites have played a key role in creating a global culture, spreading worldwide entertainment, stimulating technological interchange, and promoting trade around the world. Communications Satellites: Global Change Agents addresses communications satellites not only in terms of the technology and the services they provide, but also with consideration of the technology's impact in socio-political, security, economic, policy, news, entertainment, and cultural spheres. Editors Joseph N. Pelton, Robert J. Oslund, and Peter Marshall bring together contributions that place satellites into a broad context and examine how they influence and define today's world. Written in a non-technical, reader-friendly style, chapters investigate how satellite communications work and explore the role of satellites in such arenas as: *news and entertainment systems around the world; *Internet, E-business, and the new global economy; *global television and radio channels; *military operations; and *education, health services, economic development, and electronic immigration. Communications Satellites: Global Change Agents examines what satellites have been and projects how they will evolve in the future, articulating what they mean to the world today and forecasting what they will mean tomorrow. As the definitive source on communications satellites and their role in today's world, this volume serves as a valuable, unique, and timely resource for scholars and students in telecommunications, communication and technology, mass communication and society, and broadcasting.

Book Description
This second edition of Satellite Communications is a revised, updated, and improved version of the first edition (Van Nostrand, 1984) and has been extended to include many newer topics that are rapidly becoming important in modem and next-generation satellite systems. The first half of the book again covers the basics of satellite links, but has been updated to include additional areas such as Global Positioning and deep space satellites, dual polarization, multiple beaming, advanced satellite electronics, frequency synthesizers, and digital frequency generators. The second half of the book is all new, covering frequency and beam hopping, on-board processing, EHF and optical cross links, and mobile satellites and VSAT systems. All of these latter topics figure to be important aspects of satellite systems and space platforms of the twenty-first century. As in the first edition, the objective of the new edition is to present a unified approach to satellite communications, helping the reader to become familiar with the terminology, models, analysis procedures, and evolving design directions for modem and future satellites. The presentation stresses overall system analysis and block diagram design, as opposed to complicated mathematical or physics descriptions. (Backup mathematics is relegated to the appendices where a reader can digest the detail at his own pace. ) The discussion begins with the simplest satellite systems and builds to the more complex payloads presently being used.
