Satellite Communications

Fascinating Information Details the History, Design, Use and Future Development of Six Types of Satellites Currently Orbiting Our Planet Since the launch of the Soviet satellite Sputnik in 1957, space has been considered the latest--and perhaps final--frontier of exploration, research, espionage, and even warfare. Forty-five years after the Soviets placed the small, beeping metal ball into orbit, there are now thousands of satellites orbiting our planet with very specialized jobs. Some of them, like earth imaging satellites, photograph Earth in order to track environmental changes. Others, like communications satellites, connect the peoples of the world together in an ever faster and tighter web of radio, television, cell phone, and computer connections. Some gaze outward to explore the darkest mysteries of deep space, while others gaze down on Earth to reveal the most shadowy secrets of our enemies. The Library of Satellites examines in detail some of the most intriguing, sophisticated, and technologically advanced satellites orbiting Earth. The first "real time" communications satellite was launched in 1962, allowing live broadcasts to be viewed on both sides of the Atlantic. Today, communications satellites provide services that those first viewers would hardly have been able to imagine: hundreds of television channels that broadcast directly to three-foot dishes; crystal-clear reception of the same radio station from coast to coast; table-top, laptop, and handheld personal computers; e-mail and instant messaging that truly are instant. The future promises further mind-boggling advances that will make communication even faster and easier. Ann Byers leads an intriguing tour throughthis brave new world of space-based technology.

Donald C. Mead provides communication engineers with a comprehensive reference on direct broadcast satellite (DBS) communications. Empowered by technological developments in satellites, along with advances in MPEG technology (a set of standards for audio and video compression) DBS is now being widely deployed. This unique book provides a timely reference to both MPEG compression and the technical details of the bestselling DBS implementation, DirecTV. Providing a general overview of DBS, the history of communication satellites, and the FCC regulatory process, this book serves as an up to date reference. In addition, Mead provides the many technical facets of DBS in depth, coverage of the terrestrial systems that connect the customer to the satellite, plus specifics on the use of MPEG with DBS technology. Suitable for satellite and broadcast engineers, wireless communication engineers, and engineers working in video processing and compression, this book meets the growing demand for practical information and an authoritative reference on the topic. The many valuable case studies in the book, come from Mead's own experience and reflect technological advances made by DirecTV.

Hermes Communications Technology Satellite - The Hermes Communications Technology Satellite was an experimental high-power direct broadcast communications satellite which was also known as the CTS or simply as the Hermes. It was a joint effort of Canada's Department of Communications, who designed and managed it, NASA who launched it and provided a traveling wave guide, the European Space Agency or ESA who provided the 1200 watt solar panels and other devices.

Communications satellite - A communications satellite (sometimes abbreviated to comsat) is an artificial satellite stationed in space for the purposes of telecommunications. Modern communications satellites use geosynchronous orbits, Molniya orbits or low Earth orbits.

Canadian Satellite Communications - Canadian Satellite Communications Inc., or Cancom, is a Canadian company responsible for providing and managing the distribution of television channels to cable companies via satellite.
