This is the first book primarily about the satellite payload ofsatellite communications systems. It represents a uniquecombination of practical systems engineering and communicationstheory. It tells about the satellites in geostationary andlow-earth orbits today, both the so-called bent-pipe payloads andthe processing payloads. The on-orbit environment, mitigated by thespacecraft bus, is described. The payload units (e.g. antennas andamplifiers), 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, environmentsensitivity, and specifications. At a higher level are discussionson the payload as an entity: architecture including redundancy;specifications--what they mean, how they relate to unitspecifications, and how to verify; and specification-complianceanalysis (“budgets”) with uncertainty. Aspects ofprobability theory handy for calculating and using uncertainty andvariation are presented. The highest-level discussions, on theend-to-end communications system, start with a practicalintroduction to physical-layer communications theory. Atmosphericeffects and interference on the communications link are described.A chapter gives an example of optimizing a multibeam payload viaprobabilistic analysis. Finally, practical tips on systemsimulation and emulation are provided. The carrier frequenciestreated are 1 GHz and above. Familiarity with Fourier analysis willenhance understanding of some topics. References are providedthroughout the book for readers who want to dig deeper. Payload systems engineers, payload proposal writers,satellite-communications systems designers and analysts, andsatellite customers will find that the book cuts their learningtime. Spacecraft-bus systems engineers, payload unit engineers, andspacecraft operators will gain insight into the overall system.Students in systems engineering, microwave engineering,communications theory, probability theory, and communicationssimulation and modelling will find examples to supplementtheoretical texts.

This book throws a lifeline to designers wading through mounds of antenna array patents looking for the most suitable systems for their projects. Drastically reducing the research time required to locate solutions to the latest challenges in automotive communications, it sorts and systematizes material on cutting-edge antenna arrays that feature multi-element communication systems with enormous potential for the automotive industry. These new systems promise to make driving safer and more efficient, opening up myriad applications, including vehicle-to-vehicle traffic that prevents collisions, automatic toll collection, vehicle location and fine-tuning for cruise control systems. This book’s exhaustive coverage begins with currently deployed systems, frequency ranges and key parameters. It proceeds to examine system geometry, analog and digital beam steering technology (including "smart" beams formed in noisy environments), maximizing signal-to-noise ratios, miniaturization, and base station technology that facilitates in-car connectivity while on the move. An essential guide for technicians working in a fast-developing field, this new volume will be warmly welcomed as a powerful aid in their endeavors.

Global Mobile Satellite Systems - A Systems Overview makes mobile satellite communications understandable for communication engineers, candidates for an engineering degree, technicians, managers, and other decision makers such as financiers and regulators. It provides a systems oriented top-level view of mobile satellite communications. In particular, it focuses on Global Mobile Satellite Systems (GMSS) including active programs such as Globalstar, IRIDIUM, ORBCOMM, ACeS, and Thuraya, or so-called the second generation mobile satellite systems class. The authors start with a brief description of three generations of satellite systems in use or planned in the telecommunications industry. Selected systems architectural trades are identified and explained to illustrate how various GMSS systems are formulated, developed and evaluated. It includes an examination of market demand trends, business trades, regulatory issues as well as technical considerations. Major issues are examined in trade study style to provide easy access to key information. Key systems drivers such as orbit trades between LEO's, MEO's, and GEO's, frequency, protocols, customer bases, and regulatory and engineering issues are included. This book should appeal to individuals interested in the basic elements of Global Mobile Satellite Systems.

Rapid progress in information and communications technologies is dramatically enhancing the strategic role of information, positioning effective exploitation of these technology advances as a critical success factor in military affairs. These technology advances are drivers and enablers for the "nervous system" of the military—its command, control, communications, computers, and intelligence (C4I) systems—to more effectively use the "muscle" side of the military. Authored by a committee of experts drawn equally from the military and commercial sectors, Realizing the Potential of C4I identifies three major areas as fundamental challenges to the full Department of Defense (DOD) exploitation of C4I technology—information systems security, interoperability, and various aspects of DOD process and culture. The book details principles by which to assess DOD efforts in these areas over the long term and provides specific, more immediately actionable recommendations. Although DOD is the focus of this book, the principles and issues presented are also relevant to interoperability, architecture, and security challenges faced by government as a whole and by large, complex public and private enterprises across the economy.
