This book is a dizzyingly broad but thoroughly non-technical survey of the entire field of commercial satellite communications. Almost every conceivable aspect of the field is covered, from legal and regulatory issues, to signal processing, to orbital calculations, to satellite engineering. Chartrand has gone to great lengths to accommodate his non-technical audience; for example, even Kepler's Laws, which govern orbits, have been cast in nonmathematical terms. This emphasis necessarily reduces the depth of the treatment, but within this limitation Chartrand has provided as much detail as possible. Virtually anyone involved or interested in satellite communications but lacking a technical background will find this book useful; some examples cited in the introduction include professionals in marketing, law, finance, and journalism.
