In this revised and expanded version of Celestial Navigation in the
GPS Age, John Karl has shortened the reader's path to the first
complete celestial sight while expanding a broad range of later
topics, making this simultaneously the most accessible and the most
comprehensive book on the subject. Many books on celestial
navigation take shortcuts in explaining concepts; incorrect
diagrams and discussion are often used for the sake of moving the
student along quickly. This book tells the true story--and the
whole story. It conveys celestial navigation concepts clearly and
in the shortest possible time. It's tailored for navigation in
the GPS age--a time of computers, calculators, and web resources.
Although it covers all of the traditional methods of "working
a sight," the primary thrust is using the (under $10)
scientific calculator. Using equations that you key into your
calculator, this book guides you toward a better understanding of
the concepts of celestial navigation.
