Download or read book Dynamics of Meteor Outbursts and Satellite Mitigation Strategies written by Glenn E. Peterson and published by AIAA. This book was released on 1999 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential threat posed by Leonid meteroids to orbiting spacecraft over the next several years calls for new dynamic mitigation strategies to assist the satellite community in reducing the danger to its vehicles. This book offers deliberate dynamic mitigation strategies to complement the traditional shielding strategies, providing mission operators additional ways to decrease the danger. Five different attitude control and orbit maneuvering options are examined in detail. The information is presented in algorithmic form to allow technically competent, but meteoroid inexperienced, operators to easily understand the phenomena, assess the danger, and implement procedures. Although general in scope, the book emphasizes the Leonid meteor events of the 1998-2002 timeframe.

Download or read book Proceedings of the Third European Conference on Computer Supported Cooperative Work 13 17 September 1993 Milan Italy ECSCW 93 written by Giorgio De Michelis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer-Supported Cooperative Work (CSCW) is an interdisicplinary research area devoted to exploring the issues of designing computer-based systems that enhance the abilities of cooperating workers to coordinate and integrate their activities in an efficient, effective, and flexible manner. This rigorously selected volume represents both practical and theoretical approaches from many of the leading researchers in the field. As an interdisciplinary area of research, CSCW is characterized by bringing together widely disparate research traditions and perspectives into an arena of collaboration and contention. The selected papers reflect the diverse approaches and cultures of this multi-disciplinary field. This collection will be of interest to a wide audience - because of the huge practical import of the issues and because of the interdisciplinary nature of the problems and the solutions proposed. In particular, the volume will be of interest to researchers and professionals in computing, sociology, cognitive science, and human factors.
Download or read book Third Generation Mobile Telecommunication Systems written by Peter Stavroulakis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred years ago, the notion of transmitting information without the use of wires must have seemed like magic. In 1896, the first patent for wireless communication was granted to Marchese Guglielmo Marconi. Since then the field of wireless communications which includes cellular systems has taken various forms of development. It basically evolved through three Eras. The Pioneer Era over the period of 1860-1921, the Precellular Era over 1921-1980 and the Cellular Era after 1980 and beyond. The first generation cellular era started with the Analog Systems and evolved in the digital domain utilizing Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA), thus comprising the Second Generation Mobile Systems. The first generation RF cellular communications systems deployed in the early to mid 1980's had air interfaces comprised of analog technology. Among them were AMPS (Advanced Mobile Phone System), NMT (Nordic Mobile Telephone), and TACS (Total Access Communications System). These were designed for use in a specific geographic area and not intended to be deployed in other areas. There was not much commonality beyond using the same air interface technology and same modulation. The air interface technology was Frequency Division Multiple Access (FDMA) and the modulation was analog FM, but with different deviations and channel spacings. The frequency bands, air interface protocols, number of channels, and data rates were different. In general, these systems provided local and national coverage.
Download or read book Mobile Satellite Communications written by Madhavendra Richharia and published by John Wiley & Sons. This book was released on 2014-02-27 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demand for Mobile Satellite Service (MSS) is on the increase, with a huge surge of interest in mobile communications in recent years and high-paced advancements in the supporting system architectures, devices and applications. This thoroughly revised and updated book provides a comprehensive guide to the MSS technologies and emerging trends. It takes a system level approach, giving in-depth treatment of technical and business related issues. The author, a leading professional in the area, draws on his extensive experience in industry and research, to provide the reader with a sound and informed understanding of the technology. Mobile Satellite Communications includes introductory material for the reader new to the field, in addition to exploring prevalent system concepts, architecture, practices and trends for the more experienced. An in-depth review of scientific principles merged with business models and regulatory considerations presents a balanced perspective of commercial mobile satellite systems. This book will be of interest to practicing engineers in mobile satellite communications and mobile broadcasting, research and development professionals working in these areas, mobile satellite service providers and operators. Academics and students studying satellite systems/technology, specialists in other classes of satellite systems, technical and marketing managers, strategists and planners of telecommunication systems: individuals interested in mobile communications, satellite and telecommunications/broadcasting technology will also find this book insightful. Key Features: Comprehensive treatment of mobile satellite communications topics, including radio link aspects, satellite constellations, architectural and operational aspects, as well as business planning models, MSS radio interface standards, spectrum forecast methodologies and system examples. Addresses related themes such as mobile broadcasting, mobile VSATs, search and rescue, and navigation systems. Introduces emerging technologies such as mobile broadband, television broadcasting to handheld units, advanced capacity enhancement techniques, hybrid system architecture concepts, including a rich sample of research topics such as multiple input multiple output, satellite-based ad-hoc networks, and highlights initiatives in the use of Q/V frequency bands. Includes revision questions at the end of each chapter. An accompanying website for interaction (www.satellitesandyou.com).

Download or read book Mobile and Personal Satellite Communications 3 written by Marina Ruggieri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of Proceedings contains papers of the "Third European Workshop on Mobile/Personal Satcoms" (EMPS '98), held in Venice, Italy, November 1998. For the third time, EMPS has given to the experts an opportunity for exchanging opinions and novel ideas in the exciting field of mobile and personal satellite communications. As with the 1996 edition, EMPS '98 issued a formal call for papers, gathering a large number of contributions from many different countries. Each submitted paper has been reviewed by international referees and, finally, selected by the Workshop Steering Committee (WSC). Furthermore, key-topics in the field of mobile/personal satcoms have also been focused on through a few invited papers. As EMPS has been conceived to gather trends and novelties in the field of mobile/personal satcoms, it is tightly matched to the natural evolution of the field itself. In this frame, the reader will notice how the dominant topics are related to system and network issues, while a very little number of contributions have been provided in the propagation and channel related areas. This represents a natural trend of a field, where deep efforts have been paid in the past years to understanding and modelling the physical layer and where the present interest is mostly migrating to the applications. Further changes and novelties may be envisaged in the future of this field. I believe that EMPS will continue to represent an effective opportunity to catch and understand more deeply this evolution.
