Preface to The Satellite Communication Applications Handbook

The first edition of The Satellite Communication Applications Handbook established an important milestone in industry publications by defining the different application segments and providing up-to-date design and development information.

As with any handbook, a sufficient percentage of the material lost its timeliness not long after the start of the new millennium. It was imperative, therefore, to update and expand its content to reflect the changes in application focus and industry structure.

We did this in a way to preserve the methodical approach of the first edition while introducing a considerable amount of new technology and application information that has been gained through more recent experience and research.

The handbook is intended for anyone interested in satellite communications, whether an active member of the industry or someone considering entry into one of its segments.

The book can be read sequentially so as to follow the thread of developing ideas and processes, or it can be used as a reference on any of the specific topics, outlined next.

A technical background, while helpful, is not necessary for understanding the principles and the majority of concepts in this book.

Throughout the 1990s, the satellite communication industry experienced tremendous growth, surpassing the expectations of all who have contributed to its success.

The gross revenues in 2000 reached $60 billion, big chunks of which were contributed by satellite manufacture, launch, satellite transponder sales and leases, ground equipment supply, and direct-to-home (DTH) TV and very small aperture terminal (VSAT) data networks.

This book provides a comprehensive review of the applications that have driven this growth. It discusses the technical and business aspects of the systems and services that operators and users exploit to make money, serve and protect, and even have fun.

The book is organized into four parts, which deal with the most fundamental areas of concern to application developers and users: the technical and business fundamentals, the application of simplex (broadcast) links to multiple users, duplex links that deliver two-way interactive services, and regulatory and business affairs that drive investment and financial performance.

The 13 chapters of the book fall nicely into these general categories. Chapters 1 through 6 follow the first edition rather closely—they have been changed only to account for some of the new features developed over the intervening 7 years.

Part I consists of the first three chapters. Chapters 1 and 2 provide the basis for designing any satellite communications application, which includes finding the most appropriate structure for and suppliers of systems and technology. As in the first edition,

Chapter 2 takes the reader through the entire process of designing a satellite link with the methodology of the link budget (explained line by line).

Issues for the space segment are covered in Chapter 3 and now include details on both analog (bent-pipe) and digital onboard processing repeaters.

The reason we include this here is because of the close tie between the application and the construction of the satellite repeater, particularly if it is of the digital processing variety. Chapters 4 through 6 (Part II) are presented as in the first edition to review the scope and detail of creating a satellite television application and system.

The basics are covered in Chapter 4 from the standpoint of service possibilities: entertainment TV for local TV stations and cable, videoconferencing and business video, and distance learning.

Chapter 5 covers the range of digital TV standards such as MPEG 2 and the H series of the International Telecommunication Union (ITU) standards.

This provides the base for Chapter 6, which deals with the largest single application segment in our industry—DTH television broadcasting.

New to the handbook (Chapter 7, also in Part II) is the application called Digital Audio Radio Service (DARS), now an established service in the United States thanks to XM Satellite Radio and Sirius Satellite Radio.

Borne out of the innovative WorldSpace system that provides satellite radio programming to Africa, DARS is beginning to have the same strategic impact on terrestrial AM and FM radio as DTH had on cable and over-the-air TV.

Part III consists of Chapters 8 through 11 and deals with two-way interactive applications for data and voice. Two chapters, rather than one, are now devoted to the important topic of VSAT networks for the provision of two-way interactive data communications.

Focusing on Internet-based services (e.g., IP networks), Chapters 8 and 9 cover the enhanced capabilities of satellite-delivered interactive data to homes and businesses.

Chapter 8 reviews the uses of star and mesh VSAT networks for various applications, and Chapter 9 provides technical criteria and guidelines for how a VSAT network is sized and optimized. Chapters 10 through 13 follow the same content flow as Chapters 8 through 11 in the first edition.

In Chapter 10, which covers fixed telephony networks, we have added material on the all-important topic of voice over IP (VoIP) over satellites.

This adds to the foundation of satellite telephony for providing basic communications in remote locations and for temporary operations. Mobile telephony is covered in Chapter 11, from both geostationary Earth orbit (GEO) and non-GEO perspectives.

Most of the Mobile Satellite Service (MSS) providers continue to use GEO satellite platforms to extend service beyond ships to include handheld devices and IP-based satellite modems.

The technical and operational issues of providing MSS applications are covered in detail in this chapter. To conclude the second edition, we provide updated regulatory and business guidance in Chapters 12 and 13, respectively (Part IV).

The procedures and issues surrounding how one obtains a satellite orbit slot and Earth station license are covered in Chapter 12.

In some ways, the process has been simplified, such as with the 2001 edition of the Radio Regulations of the International Telecommunication Union. Issues of gaining access and licenses in specific countries continue to be a challenge, and so we cover this topic to give readers a head start in the process.

Finally, the business of satellite communication is described in Chapter 13, where the industry is divided up by the elements of a typical satellite application.

This gives developers of new applications a framework for organizing and managing the process of going from the idea to a revenue-generating resource or entire network.

Anyone entering this exciting field at this time has many options to consider and many avenues to follow. Fortunately, there is a great deal of useful information and experience available to anyone who wishes to do the research and explore its many dimensions.

The origin of this book comes from the author’s journey of more than 30 years as an independent consultant and educator, at Hughes Electronics, COMSAT, Western Union, and the U.S. Army Signal Corps (where one really learns how to communicate).
