Download or read book The ITU and Managing Satellite Orbital and Spectrum Resources in the 21st Century written by Audrey L. Allison and published by Springer Science & Business. This book was released on 2014-05-03 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Access to satellite orbits and spectrum is managed by the ITU, a United Nations body that strives to extend the benefits of new technologies to the world, while ensuring equitable access to these resources. This book explores how the ITU approaches these dual missions in light of the increasing saturation of the geostationary orbit by a vibrant global satellite industry and the rising interests of developing countries in accessing these limited resources. These issues were the subject of debate at the 2012 World Radiocommunication Conference. This book describes and assesses various regulatory approaches undertaken to manage the increasing requests for access to space and especially access to spectrum and orbital locations in the geosynchronous or “The Clarke” orbit.

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.

Download or read book Space Warfare in the 21st Century written by Joan Johnson-Freese and published by Routledge. This book was released on 2016-11-08 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the recent shift in US space policy and the forces that continually draw the US back into a space-technology security dilemma. The dual-use nature of the vast majority of space technology, meaning of value to both civilian and military communities and being unable to differentiate offensive from defensive intent of military hardware, makes space an area particularly ripe for a security dilemma. In contrast to previous administrations, the Obama Administration has pursued a less militaristic space policy, instead employing a strategic restraint approach that stressed multilateral diplomacy to space challenges. The latter required international solutions and the United States, subsequently, even voiced support for an International Code of Conduct for Space. That policy held until the Chinese anti-satellite (ASAT) test in 2013, which demonstrated expanded Chinese capabilities. This volume explores the issues arising from evolving space capabilities across the world and the security challenges this poses. It subsequently discusses the complexity of the space environment and argues that all tools of national power must be used, with some degree of balance, toward addressing space challenges and achieving space goals. This book will be of much interest to students of space policy, defence studies, foreign policy, security studies and IR.

Download or read book The 21st Century Media r evolution written by Jim Macnamara and published by Peter Lang. This book was released on 2010 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of 'new media' and social media is widely discussed in contemporary society. However, media and public communication are mostly analyzed within particular theoretical frameworks and within specific disciplinary fields. Such approaches have created polarized views on media and communication, and fail to create an understanding of the interdependencies between these fields. This book expertly synthesizes competing theories and disciplinary viewpoints, integrates scholarly and cutting edge research, and examines international data from fast-growing markets including China, to provide a comprehensive, holistic view of the twenty-first century (r)evolution in media and public communication. The book identifies how the changes are located in practices rather than technologies and that these practices are emergent in highly significant ways. Engaging and accessible, the book is essential reading for media scholars and communication professionals, and a valuable text for courses in media studies, journalism, advertising, public relations, and organisational and political communication.
