Auhtor of The Satellite Communication Ground Segment and Earth Station Handbook

Bruce R. Elbert, the author of eight Artech House books on satellite communications and information technology, has 45 years of technical and management experience in these fields.

As president of the Application Technology Strategy, a consulting and training firm based in Texas, he assists corporations and government agencies in developing their technical and operational capabilities in satellite and broadband communications systems. Mr. Elbert was with Hughes Electronics for 25 years.

He held several key management positions, including director of marketing and engineering for the Galaxy satellite system, and senior communications engineering manager for Indonesia’s first domestic satellite network, Palapa A. His first industry position was as a satellite systems engineer with COMSAT back in the early days of communications satellites.

He holds masters degrees in business administration (Pepperdine University, 1985) and electronics engineering and computer science (University of Maryland, 1972), and obtained his bachelor of electrical engineering from CCNY in 1965.

Mr. Elbert served in the U.S. Army as a captain and radio communications officer, including a tour in Southeast Asia with the 4th Infantry Division.

He is series editor of two Artech House Libraries: Space Technology and Applications and Technology Management and Professional Development.

Preface to The Satellite Communication Ground Segment and Earth Station Handbook

Our ability to apply space technology to communication needs on earth is necessarily dependent on the ground segment and the earth stations that comprise it.

Little has been documented on the methodologies and practices that ground segment developers employ to design and implement these facilities.

Another aspect is the powerful trend toward consumer-style user terminals that bring satellite communications down to an affordable and practical level, and by doing so have caused the satellite use to reach substantial populations.

Doing so has not reduced demands on the larger earth stations used as hubs and gateways; rather, the opposite has occurred.

This situation was the primary motivation for this handbook, and we were able to draw on over 40 years of development in this field when putting it together.

The book is organized into 11 chapters that discuss the history, requirements, systems engineering, hardware design, systems analysis, and operations and maintenance of earth stations and user terminals.

Our approach is to provide a thorough understanding of the technology and implementation issues for the ground segment, rather than delving into copious detail on each element.

This is how we could keep the book to a tractable form and allow the reader to learn how to develop specific approaches for fixed, broadcasting, and mobile satellite applications.

A cover-to-cover reading will provide a comprehensive review of almost every aspect of the system, considering real-world aspects of earth station design and engineering.

From there, the book provides a reference and technologies to be incorporated for subsequent analysis and selection of the appropriate architecture design approach.

References containing detailed information on specific engineering issues and solutions are included with each chapter.

We begin in Chapter 1 with a brief history of the satellite communication earth station, which is fundamentally a radio station operating at microwave frequencies.

We draw heavily from the fields of radio-astronomy (the first dish antennas were actually radio-telescopes), radar, and terrestrial microwave. Basic engineering principles common to all earth stations are contained in Chapters 2 and 3, the latter delving in particular into the RF link budgeting process for geostationary earth orbit (GEO) and non-GEO satellite transmissions.

Chapter 4 addresses ground segment requirements for two-way communications services for telephony and VSAT data applications.

One-way (broadcast) service requirements are covered in detail in Chapter 5, is by addressing digital video broadcasting as well as audio and data broadcasting.

The data aspects are of particular interest in the context of applying the Internet Protocol over satellite links. Chapter 6 addresses what has become a vital concern in designing integrated ground segments for digital services—that of baseband architecture.

The topic, which defied proper characterization in the past, involves complex data processing, information transfer over a network, multiple access tradeoffs, modulation and coding, and a host of other aspects of creating an automated network environment that satisfies subscribers and other users.

We address an overriding concern about implementing a competitive architecture that can make money in commercial services. Also of importance is the demand for enhanced transportable and in-motion systems to serve emergency and military needs.

The more traditional topic of earth station RF and equipment design is addressed in detail in Chapter 7, extending from the general subject of gain budgets (EIRP and G/T) to the specifics of the antennas, high power, and low noise amplifiers, and up- and down-converters.

We provide up-to-date coverage of high power solid-state amplifiers as a replacement for traditional vacuum-tube base units.

Also considered in the chapter are important design and performance issues such as group delay, local oscillator stability, and phase noise.

Interaction of all of the RF and baseband elements are covered in Chapter 8, which deals with signal impairments and PC software tools for link analysis and end-to-end simulation.

Our next focus is on fixed and mobile user terminals, covered in Chapter 9 from a design and performance standpoint.

Also addressed is the development of baseband and modem functions through the principles of the software designed radio, as well as specific considerations for handheld satellite phones.

Design requirements and implementation of major facilities for large earth stations are covered in detail in Chapter 10.

We round out the handbook in Chapter 11 with a comprehensive discussion of operations and maintenance principles based on practical experience with many successful projects over the years.

This considers both the operational needs of the earth station and network, as well as lessons learned in managing the human side of the equation.

This second edition of the handbook is intended for working satellite communications engineers, telecommunications specialists, and managers who need to consider how to design, implement, and manage the ground segment.

It is also appropriate for specialists in RF, baseband, information network technology, and space systems who wish to gain a better understanding of the total system and the interaction of its key elements.

Operations and maintenance personnel should find the book useful as an introduction to ground segments and earth stations, and as a handy reference. From an education standpoint, much of the material is in current use for technical training.

There is a lot that goes into a book like this, which captures much of a lifetime’s experience with the practical side of applying technology to a real need.

I would like to express my appreciation to my technical reviewer, Ray Sperber, to whom this second edition is dedicated, for his outstanding guidance and input during the development of the manuscript.

His insight, motivation, and mastery of all things satellite have helped me make this a better book. Also, I wish to thank Bill Bazzy, Mark Walsh, and Samantha Ronan of Artech House for their support from start to finish.

I am very appreciative of my wife, Cathy, for helping get the project together and to my younger daughter, Michelle, who kept us moving forward with research assistance.

I especially thank my older daughter, Sheri Lucas, who educated me on the value and fine points of engineering a sustainable facility (see Section 10.5).
