This book was released on 2018-06-20 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communications systems have always been a critical element in aviation. Until recently, nearly all communications between the ground and aircraft have been based on analog voice technology. But the future of global aviation requires a more sophisticated "information infrastructure" which not only provides more and better communications, but integrates the key information functions (communications, navigation, and surveillance) into a modern, network-based infrastructure. Satellite communications will play an increasing role in providing information infrastructure solutions for aviation. Developing and adapting satellite communications technologies for aviation use is now receiving increased attention as the urgency to develop information infrastructure solutions grows. The NASA Glenn Research Center is actively involved in research and development activities for aeronautical satellite communications, with a key emphasis on air traffic management communications needs. This paper describes the recent results and status of NASA Glenn's research program. Kerczewski, Robert J. Glenn Research Center NASA/TM-2001-211150, E-13003, NAS 1.15:211150

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.

This book was released on 2019-03-15 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern systems and means of aeronautical radio communication are continuously being improved, but without the development of new technical means, the aviation industry suffers. The development of more innovative plans of aviation technology are needed in order to respond to the ever-increasing standard of aviation technology. Recent Advances in Satellite Aeronautical Communications Modeling is devoted to the modeling of satellite communication channels for aircraft and RPAS/UAV using the Matlab Simulink and NetCracker software. Featuring research on topics such as channel coding, microwave emitters, and array modeling, this book is ideally designed for scientists, engineers, air traffic controllers, managers, researchers, and academicians.

This book was released on 2014-07-01 with total page 0 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.
