Celestial Navigation in the GPS Age

Klappentext 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.
