Satellites For World Communication

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.

Communication Satellites, Fifth Edition, chronicles the worldwide development of communication satellites over a period of more than four decades. Descriptive text and tabular data are presented for experimental and operational satellites of communications and broadcasting systems of individual nations and international organizations. Descriptions are enhanced by drawings of satellites, communication subsystem block diagrams, and coverage maps. The book includes extensive references and a supplemental bibliography.

Global mobile satellite communications (GMSC) are specific satellite communication systems for maritime, land and aeronautical applications. It enables connections between moving objects such as ships, vehicles and aircrafts, and telecommunications subscribers through the medium of communications satellites, ground earth stations, PTT or other landline telecommunications providers. Mobile satellite communications and technology have been in use for over two decades. Its initial application is aimed at the maritime market for commercial and distress applications. In recent years, new developments and initiatives have resulted in land and aeronautical applications and the introduction of new satellite constellations in non-geostationary orbits such as Little and Big LEO configurations and hybrid satellite constellations as Ellipso Borealis and Concordia system. This book is important for modern shipping, truck, train and aeronautical societies because GMSC in the present millennium provides more effective business and trade, with emphasis on safety and commercial communications. Global Mobile Satellite Communications is written to make bridges between potential readers and current GMSC trends, mobile system concepts and network architecture using a simple mode of style with understandable technical information, characteristics, graphicons, illustrations and mathematics equations. Global Mobile Satellite Communications represents telecommunications technique and technology, which can be useful for all technical staff on vessels at sea and rivers, on all types of land vehicles, on planes, on off shore constructions and for everyone possessing satellite communications handset phones.

The first comprehensive account of the development of communication satellites and their political, economic, social, and cultural impact over the past twenty-five years.

Trends in Communications Satellites offers a comprehensive look at trends and advances in satellite communications, including experimental ones such as NASA satellites and those jointly developed by France and Germany. The economic aspects of communications satellites are also examined. This book consists of 16 chapters and begins with a discussion on the fundamentals of electrical communications and their application to space communications, including spacecraft, earth stations, and orbit and wavelength utilization. The next section demonstrates how successful commercial satellite communications have become, citing the INTELSAT series of satellites. The forerunners of INTELSAT satellites are mentioned, and the major characteristics of all INTELSAT satellites are surveyed. One chapter is devoted to the rapidly growing use of communications satellites for various domestic systems, focusing on the systems developed by the Hughes Aircraft Company for Canada, Indonesia, and the United States. The next section considers the economics of communications satellite systems using the INTELSAT and COMSAT experience. The concluding section presents a compilation in tabular and graphical form of the physical characteristics of the satellites discussed in the text. This monograph will be a useful resource for satellite communications engineers as well as policymakers concerned with communications satellites and space exploration more generally.
