“This book sets the record straight on just how remarkable has been the rise and rise of position-determination–the Global Positioning System, or GPS….(The) writers have combined their considerable talents to tell a highly readable story about the development of satellite navigation system….The book is a good primer and a stimulus to the more challenging aspects of what is now one of the fastest growing sectors in space applications.”
