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.
