Global Mobile Satellite Communications


Book Description

Global mobile satellite communications (GMSC) are specific satellite communication systems for maritime, land and aeronautical applications. It enables connections between moving objects such as ships, vehicles and aircrafts, and telecommunications subscribers through the medium of communications satellites, ground earth stations, PTT or other landline telecommunications providers. Mobile satellite communications and technology have been in use for over two decades. Its initial application is aimed at the maritime market for commercial and distress applications. In recent years, new developments and initiatives have resulted in land and aeronautical applications and the introduction of new satellite constellations in non-geostationary orbits such as Little and Big LEO configurations and hybrid satellite constellations as Ellipso Borealis and Concordia system. This book is important for modern shipping, truck, train and aeronautical societies because GMSC in the present millennium provides more effective business and trade, with emphasis on safety and commercial communications. Global Mobile Satellite Communications is written to make bridges between potential readers and current GMSC trends, mobile system concepts and network architecture using a simple mode of style with understandable technical information, characteristics, graphicons, illustrations and mathematics equations. Global Mobile Satellite Communications represents telecommunications technique and technology, which can be useful for all technical staff on vessels at sea and rivers, on all types of land vehicles, on planes, on off shore constructions and for everyone possessing satellite communications handset phones.




Mass Communications Research Resources


Book Description

This reference book is designed as a road map for researchers who need to find specific information about American mass communication as expeditiously as possible. Taking a topical approach, it integrates publications and organizations into subject-focused chapters for easy user reference. The editors define mass communication to include print journalism and electronic media and the processes by which they communicate messages to their audiences. Included are newspaper, magazine, radio, television, cable, and newer electronic media industries. Within that definition, this volume offers an indexed inventory of more than 1,400 resources on most aspects of American mass communication history, technology, economics, content, audience research, policy, and regulation. The material featured represents the carefully considered judgment of three experts -- two of them librarians -- plus four contributors from different industry venues. The primary focus is on the domestic American print and electronic media industries. Although there is no claim to a complete census of all materials on print journalism and electronic media -- what is available is now too vast for any single guide -- the most important and useful items are here. The emphasis is on material published since 1980, though useful older resources are included as well. Each chapter is designed to stand alone, providing the most important and useful resources of a primary nature -- organizations and documents as well as secondary books and reports. In addition, online resources and internet citations are included where possible.




International Regimes for the Final Frontier


Book Description

Neither rational choice theory, with its emphasis on interest calculation, nor sociological institutionalist theory, with its emphasis on identity-defined rule following, indicates how governments determine which of their multiple interests or identities are at stake in a particular situation or how they develop mutual comprehension of each other's goals. International Regimes for the Final Frontier addresses these gaps by tracing how governments approach an unfamiliar issue—in this case, international agreements regulating human activity in outer space between 1958 and 1988—and examines three ways situation definitions channel governments' approaches to issues or problems.




Satellite Communications


Book Description

This second edition of Satellite Communications is a revised, updated, and improved version of the first edition (Van Nostrand, 1984) and has been extended to include many newer topics that are rapidly becoming important in modem and next-generation satellite systems. The first half of the book again covers the basics of satellite links, but has been updated to include additional areas such as Global Positioning and deep space satellites, dual polarization, multiple beaming, advanced satellite electronics, frequency synthesizers, and digital frequency generators. The second half of the book is all new, covering frequency and beam hopping, on-board processing, EHF and optical cross links, and mobile satellites and VSAT systems. All of these latter topics figure to be important aspects of satellite systems and space platforms of the twenty-first century. As in the first edition, the objective of the new edition is to present a unified approach to satellite communications, helping the reader to become familiar with the terminology, models, analysis procedures, and evolving design directions for modem and future satellites. The presentation stresses overall system analysis and block diagram design, as opposed to complicated mathematical or physics descriptions. (Backup mathematics is relegated to the appendices where a reader can digest the detail at his own pace. ) The discussion begins with the simplest satellite systems and builds to the more complex payloads presently being used.
