Introduction

As with previous editions, the fourth edition provides broad coverage of satellite communications, while maintaining sufficient depth to lay the foundations for more advanced studies. Mathematics is used as a descriptive tool and to obtain numerical results, but lengthy mathematical derivations are avoided. In setting up numerical problems and examples the author has made use of Mathcad™, a computer program, but the worked examples in the text are presented in normal algebraic notation, so that other programs, including programmable calculators can be used. The main changes compared to the previous edition are as follows. In Chap. 1 the sections on INTELSAT and polar orbiting satellites, including environmental and search and rescue, have been updated. Sun-synchronous orbits have been treated in more detail in Chap. 2. A new section on planar antennas and arrays, including reflect arrays, and array switching has been added in Chap. 6. Chapter 8 includes additional details on C-band reception of television signals. In Chap. 11, a more detailed description is given of linear block codes, and new sections on the Shannon capacity and turbo and low density parity check (LDPC) codes have been included. Chapter 12 has a new section on antisatellite links (ISLs), including optical links. Chapter 15 has been extensively rewritten to include more basic details on networks and asynchronous transfer mode (ATM) operation. Chapter 16 covers high definition television (HDTV) in more detail, and the Iridium mobile satellite system, which is now under new ownership, is described in Chap. 17
