Query: Outstanding Intro to Satellites

An excellent introduction to satellite communications. I use this book constantly to provide non-engineers and engineers alike with simple answers to common questions. I hand this book out to new employees as well as customers so that we can speak a common language.In addition, with the authors permission I used this as the textbook to teach students a Vo-Technical high school.I highly recommend this book.
