Download or read book Satellite Communications Payload and System written by Teresa M. Braun and published by John Wiley & Sons. This book was released on 2012-08-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005-07-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States must operate successfully in space to help assure its security and economic well being. The Department of the Navy is a major user of space capabilities, although those capabilities are now primarily provided by DOD, the Air Force, and NOAA. Following a DOD assessment of national space security management in 2001, the Navy commissioned a Panel to Review Space to assess Navy space policy and strategy. As an extension of that review, the NRC was requested by the Navy to examine its needs in space for providing future operational and technical capabilities. This report presents a discussion of the strategic framework of future space needs, the roles and responsibilities for meeting those needs, an assessment of Navy support to space mission areas, and a proposed vision for fulfilling Naval forces space needs.

Download or read book ORIGINS SATELLITE COMM written by WHALEN DAVID J and published by Smithsonian Institution Scholarly Press. This book was released on 2002-08-17 with total page 248 pages. 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.
