Preface: Introduction to Satellite Communication is designed to meet the needs of working professionals and students. The first edition was a response to a request by many friends and associates for a basic and clear book that provides newcomers with an accessible way to gain knowledge and become productive. The second edition followed the same approach, updating the older and dated material and adding background in newer systems, particularly the global mobile personal communications systems introduced worldwide. This third edition brings the text in line with industry and technology trends. Whether the reader is technically trained or not, the need exists for an authoritative guidebook to the construction and usage of satellite networks.
This book is designed to give you, the reader, an understanding that should permit you to begin work as a satellite professional or as a user of satellite communication. Sufficient technical information has been included to instill a feeling for how systems are designed and operate. Many categories of professionals and students should profit from a significant portion of the material. The book’s explanatory nature and broad coverage make it suitable as a textbook for university programs and internal training in communication systems design and planning. Nontechnical professionals in associated business management, contracts, legal, and financial fields will find the book particularly helpful when they must deal with telecommunication projects and issues.
The book is organized into 12 chapters to correspond to the major areas of commercial satellite communication systems. Chapter 1, ‘‘Fundamentals of Satellite Systems,’’ identifies the structure and key features of satellite communication and reviews some of the more basic concepts in a nontechnical style. It is understandable to all readers, including high school students. Likewise, Chapter 2, ‘‘Evolution of Satellite Communication,’’ provides an easy-to-understand history of the technology and its applications. It begins with geostationary Earth orbit (GEO) systems, which are the foundation of the industry, and moves into non-GEO systems used in mobile applications. Another purpose of Chapter 2 is to capture in one place the background with which many newcomers otherwise would not be acquainted (e.g., how we got from Arthur C. Clarke’s concept in 1945 to the present day). Chapter 3, ‘‘Satellite Network Architectures,’’ covers the ways in which satellite links can be applied to practical communication problems. It gives the reader an appreciation for the variety of uses in which satellites have gained a stronghold. Technologists involved with spacecraft or communication systems will find that Chapter 3 explains many of the mysteries surrounding the business of using satellites.
The next two chapters begin the core technical material, focusing on the engineering and design of radio transmissions to and from satellites. Chapter 4, ‘‘Microwave Link Engineering,’’ gives the reader a basic understanding of the physics of the radio link between the Earth station and the satellite and covers the factors that are under the designer’s control as well as those that are not. It is assumed that the reader has little or no technical training, so the only form of mathematics used is arithmetic. Chapter 5, ‘‘Modulation, Multiple Access and Impairments,’’ rounds out the basic theory of communication as it relates to efficient satellite transmission. The chapter is fairly compact and may be helpful for interested readers to supplement their study with a basic textbook on communication engineering. Nontechnical readers can examine Chapters 4 and 5 but not delve deeply into the engineering details (which are more important to technical professionals, who need to understand features and trade-offs).
Chapters 6, 7, and 8 provide a comprehensive review of the functional elements of all communication satellites. The objective here is to aid readers in understanding the key issues in satellites and is not appropriate for the detailed engineering design of satellite components and subsystems. As is customary, the physical piece of hardware is referred to as the spacecraft, which becomes an artificial Earth satellite (or just satellite) when in orbit. The major elements of the spacecraft are the repeater (bent-pipe and digital processor), the antennas, and the spacecraft bus (the supporting vehicle), which are covered in Chapters 6, 7, and 8, respectively. While those chapters are not essential to understanding how to use satellite communications, they will be of general benefit because the actual operation of a spacecraft affects the performance of the services rendered.
The complementary topics for the ground facilities used in conjunction with the satellite are reviewed in Chapter 9, ‘‘Earth Stations and Terrestrial Technology.’’ Care has been taken to include only current classes of Earth stations, particularly those used for satellite control, television broadcasting, fixed and mobile very small aperture terminal (VSAT) applications, and mobile satellite services (GEO and non-GEO). Chapter 9 will be useful for those readers who plan to use satellite transmission, since ground facilities fundamentally are under the control of the user rather than the satellite operator.
Chapter 10, ‘‘Launch Vehicles and Services,’’ covers topics that are of great concern to operators and major users of satellites alike. The chapter is a complete review of the alternatives for placing satellites into Earth orbit and emphasizes that particular launch vehicle choices change over time. However, because reliability is based on a consistent experience record, much of the change is evolutionary rather than revolutionary. Chapter 10 also discusses the planning and operation of the mission, which is the sequence of events of launch and placement into operating orbit. Risk management is addressed as well.
Chapter 11, ‘‘Satellite Operations and Organization,’’ addresses the special needs of this type of business. In some detail, it reviews the complete satellite control system, the communication network needed to support such a system, and the human resources that are appropriate to those functions. Chapter 12, ‘‘Economics of Satellite Systems,’’ provides the underlying characteristics of satellites and Earth stations that are related to the cost of implementing and operating satellite networks. Our perspective is that of a commercial operator who is in business to make money (or reduce costs). The framework is useful for analyzing the economics of either a complete system or a portion of a system (e.g., one or a few Earth stations). Chapter 12 is expanded to address the overall systems engineering process in satellite communication. This is based on the structured approach found in the aerospace industry adapted to the needs of commercial applications. From this, we move into the topic of engineering economics and overall development of the entire satellite program.
The book can be read sequentially from cover to cover because the material follows a consistent thread. All the elements and uses of spacecraft and Earth stations are covered. Chapters also can be read out of sequence, if necessary, because each chapter explains the concepts relevant to it. References to other chapters are provided throughout. The material is completely current as of the time of publication (circa 2008), but care has been taken to emphasize concepts that are not likely to change quickly. That is the same approach taken in the first edition, a book that remained in print (and in demand) for 12 years. Once read, this book can be used as a reference because most of the terminology in current usage is defined and illustrated. This book is a mate to the author’s previous work, The Satellite Communication Applications Handbook, Second Edition, and The Satellite Communication Ground Segment and Earth Station Handbook.
