About this title

Synopsis

Master practical celestial navigation with a time-tested method for finding longitude.

This guide explains how lunar distances are used with the Nautical Almanac to compare observed positions with geocentric distances, and how to correct for refraction and parallax. It also covers the step-by-step process, from taking measurements to interpolating Greenwich mean time, using clear formulas and classic techniques.

The text presents the methods in accessible terms, emphasizing real-world observation and calculation. It shows how to manage the complex factors involved, including the motions of the Moon, planets, and stars, and how to translate observations into precise time and location data. By following the procedures, readers gain a solid foundation in practical spherical astronomy.

How lunar distances are observed and prepared for comparison with geocentric distances
Corrections for refraction and parallax to turn observed data into true values
Interpolation and successive approximation techniques for Greenwich time
Alternative methods and historical context for mastering lunar-distance calculations

Ideal for students, navigators, and enthusiasts who want a reliable, hands‑on approach to celestial navigation and practical astronomy.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
