Celestial Navigation in the GPS
Age
Covers all modern methods of celestial
navigation including H.O. 229 and 249, direct calculations
using calculators and 72 different exercises in five
categories of interest.
Celestial navigation is a crucial
skill for the offshore navigator. This book provides the
shortest path to acquiring that skill.
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.
In addition, you will learn novel ways
to plot lines of position, ways to check your sextant
accurately by star sights, and how to tell time from a moon
sight. The many appendices are a treasure of references and
explanations of abstract ideas.
This may not be the only book you read
while learning celestial navigation, but it certainly should
be one of them. |
