Available in PDF, EPUB and Kindle. Book excerpt: Conventional assumptions hold that U.S. government research and development efforts produced the satellite communications industry. David J. Whalen has looked deeply into the history of the industry and presents remarkable new information to tell a much different story. He finds that most of the satellite technology was privately developed by AT&T and Hughes Aircraft Company, and that the market for satellite communications existed before the government stepped in. In this detailed history of satellite communication's earliest years, Whalen explains that NASA, the White House, and Congress intervened in satellite communications development to show the world that the U.S. was in the space race and that the billions of dollars the U.S. government planned to spend would result in practical applications. He traces many different outcomes of government intervention, such as the marginalization of AT&T, who designed and paid for the first real communication satellite, Telstar 1; the positioning of Hughes as the dominant commercial satellite manufacturer; and the establishment of geosynchronous Earth orbit as the preferred orbit. Had the market been allowed to operate freely, AT&T would have launched their commercial low-earth-orbit telephone satellite in the 1960s. Many previous histories of satellite communications have emphasized government contributions; this version is the first to focus on the industry's contributions.

Available in PDF, EPUB and Kindle. Book excerpt: A fascinating account of how the United States established the first global satellite communications system to project geopolitical leadership during the Cold War. On July 20, 1969, the world watched, spellbound, as NASA astronaut Neil Armstrong stepped off the Apollo 11 lunar module to walk on the moon. NASA estimated that 20 percent of the planet's population—nearly 650 million people—watched the moon landing footage, which was made possible by the first global satellite communications system, the International Telecommunications Satellite Organization, or Intelsat. In Beyond Sputnik and the Space Race, Hugh R. Slotten analyzes the efforts of US officials, especially during the Kennedy administration, to establish this satellite communication system and open it to all countries of the world. Locked in competition with the Soviet Union for both military superiority and international prestige, President John F. Kennedy overturned the Eisenhower administration's policy of treating satellite communications as simply an extension of traditionally regulated telecommunications. Instead of allowing private communications companies to set up separate systems that would likely primarily serve major "developed" regions, the new administration decided to take the lead in establishing a single world system. Explaining how the East-West Cold War conflict became increasingly influenced by North-South tensions during this period, Slotten highlights the growing importance of non-aligned countries in Asia, Latin America, and Africa. He also underscores the importance of a political economy of "total Cold War" in which many crucial aspects of US society became tied to imperatives of national security and geopolitical prestige. Drawing on detailed archival records to examine the full range of decisionmakers involved in the Intelsat system, Beyond Sputnik and the Space Race spotlights mid- and lower-level agency staff usually ignored by historians. One of the few works to analyze the establishment of a major global infrastructure project, this book provides an outstanding analytical overview of the history of global electronic communications from the mid-nineteenth century to the present.

Book excerpt: "Fifty years after the founding of NASA, from 28 to 29 October 2008, the NASA History Division convened a conference whose purpose was a scholarly analysis of NASA's first 50 years. Over two days at NASA Headquarters, historians and policy analysts discussed NASA's role in aeronautics, human spaceflight, exploration, space science, life science, and Earth science, as well as crosscutting themes ranging from space access to international relations in space and NASA's interaction with the public. The speakers were asked to keep in mind the following questions: What are the lessons learned from the first 50 years? What is NASA's role in American culture and in the history of exploration and discovery? What if there had never been a NASA? Based on the past, does NASA have a future? The results of those papers, elaborated and fully referenced, are found in this 50th anniversary volume."--Introduction.

Book excerpt: The compelling and little-known history of satellite communications that reveals the Soviet and Eastern European roles in the development of its infrastructure. Taking its title from Hannah Arendt’s description of artificial earth satellites, No Heavenly Bodies explores the history of the first two decades of satellite communications. Christine E. Evans and Lars Lundgren trace how satellite communications infrastructure was imagined, negotiated, and built across the Earth’s surface, including across the Iron Curtain. While the United States’ and European countries’ roles in satellite communications are well documented, Evans and Lundgren delve deep into the role the Soviet Union and other socialist countries played in shaping the infrastructure of satellite communications technology in its first two decades. Departing from the Cold War binary and the competitive framework that has animated much of space historiography and telecommunications history, No Heavenly Bodies focuses instead on interaction, cooperation, and mutual influence across the Cold War divide. Evans and Lundgren describe the expansion of satellite communications networks as a process of negotiation and interaction, rather than a simple contest of technological and geopolitical prowess. In so doing, they make visible the significant overlaps, shared imaginaries, points of contact and exchange, and negotiated settlements that determined the shape of satellite communications in its formative decades.

Available in PDF, EPUB and Kindle. Book excerpt: October 1995 marked the fiftieth anniversary of Arthur C. Clarke's famous article in Wireless World proposing the use of satellites placed in geosynchronous orbit for worldwide communications relay. The article proved prophetic, for it heralded the modern era of telecommunications. Beginning in the early 1960s, several series of satellites were launched into Earth's orbit; collectively they transformed the latter twentieth century, creating a global village of instantaneous communications. Previously, the ionosphere had defined the limits of radio communication; today, by going beyond the ionosphere, broadband telecommunication has entered a new age. This book describes the first attempts to go beyond the ionosphere, including both the earliest uses of the Moon as a passive, natural relay satellite and Project Echo, the massive inflated satellite off which Earth stations bounced radio signals, as well as contemporary communications via active-repeater artificial moons in orbit about the Earth. It analyzes both American and foreign satellite communications, the histories of several satellite communications companies, the roles of government agencies, and the contribution of research laboratories. The book is a collection of papers originally presented during an international symposium held in Washington, D.C., at the time of the fiftieth anniversary of Clarke's 1945 article. Contributions from historians and other scholars from throughout the world present a stimulating analysis of one of the most important global technologies at work today—and how it originated and evolved.

Download or read book Satellite Communication Systems Design written by S. Tirró and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writing a comprehensive book on satellite communications requires the com mand of many technical disciplines and the availability of up-to-date information on international recommendations, system architectures, and equipment stand ards. It is therefore necessary to involve many authors, each possessing a good level of knowledge in a particular discipline. The problem of using a coherent and unambiguous set of definitions and basic terms has been solved by including in the book all the background information needed for understanding satellite communication systems, without any major reference to other textbooks specializing in particular disciplines. The obvious consequence of this approach has been the large size of the book, with the advantages, however, of practically complete independence from other books, more systematic discussion of the subject matter, and better readability. After the required background information, emphasis has been placed on the discussion of techniques and system design criteria rather than on specific equipment implementation or description of particular systems. The book may be divided in five parts as follows: • The first five chapters provide most of the required background information. • Chapter 6 is an introductory outline of satellite communication systems. • Chapters 7 to 13 deal with the various aspects of technical system design. • Chapter 14 discusses system economics. • Chapter 15 provides a brief insight into some foreseeable future develop ments of satellite communications.

Available in PDF, EPUB and Kindle. Book excerpt: Extensive revision of the best-selling text on satellite communications — includes new chapters on cubesats, NGSO satellite systems, and Internet access by satellite There have been many changes in the thirty three years since the first edition of Satellite Communications was published. There has been a complete transition from analog to digital communication systems, withanalog techniques replaced by digital modulation and digital signal processing. While distribution of television programming remains the largest sector of commercial satellite communications, low earth orbit constellations of satellites for Internet access are set to challenge that dominance. In the third edition, chapters one through three cover topics that are specific to satellites, including orbits, launchers, and spacecraft. Chapters four through seven cover the principles of digital communication systems, radio frequency communications, digital modulation and multiple access techniques, and propagation in the earth’s atmosphere, topics that are common to all radio communication systems. Chapters eight through twelve cover applications that include non-geostationary satellite systems, low throughput systems, direct broadcast satellite television, Internet access by satellite, and global navigation satellite systems. The chapter on Internet access by satellite is new to the third edition, and each of the chapters has been extensively revised to include the many changes in the field since the publication of the second edition in 2003. Two appendices have been added that cover digital transmission of analog signals, and antennas. An invaluable resource for students and professionals alike, this book: Focuses on the fundamental theory of satellite communications Explains the underlying principles and essential mathematics required to understand the physics and engineering of satellite communications Discusses the expansion of satellite communication systems in areas such as direct-broadcast satellite TV, GPS, and internet access Introduces the rapidly advancing field of small satellites, referred to as SmallSats or CubeSats Provides relevant practice problems based on real-world satellite systems Satellite Communications is required reading for undergraduate and postgraduate students in satellite communications courses and an authoritative reference for engineers working in communications, systems and networks, and satellite operations and management.
