Trends in Communications Satellites


Book Description

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.

Communications Satellites


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.
