This book acts as a manual for the ancient methods of navigating by the stars, which continue to provide the sailor or pilot with a timeless means of determining location. Despite the prevalence of GPS, a comprehensive set of formulae that can be evaluated on any inexpensive scientific calculator in the event of a catastrophic software or systems failure is a vital failsafe. It also serves as a living link to centuries of explorers from centuries past. Beginning with the basics of positional astronomy, this guide moves on to the more complex math necessary to understand the ephemerides, tables showing the future positions of the stars and planets. These astronomical almanacs were the satellite navigation of their day. The objective of this book is twofold: to provide the reader with a concise, comprehensible manual on positional astronomy as it applies to astro-navigation and to furnish the concise algorithms for finding the position of the Sun and various navigational stars at any given instant. In a world where too many mariners and aeronauts rely solely on technology and are vulnerable to solar flares, electrical issues, and the like, this knowledge can be a life-saving backup, not to mention a fascinating study in its own rights. Included is an exact mathematical way to determine your position in the air or on the sea far more quickly and accurately than by using the old celestial navigational method, without even needing to know or understand the underlying mathematics. There is even a section that teaches how to measure the azimuth of a star using an analog wrist watch so if a sextant gets damaged, locating position is still possible. This book offers mathematicians and adventurers a way to determine position when the skies go dark. The U.S. Navy has recently realized that their electronic navigation systems are vulnerable to cyberattack, and as a result has instructed the Naval Academy to begin teaching celestial navigation again.

An ideal introduction to astronomy and astro navigation. 178 letter size pages packed with full colour illustrations, detailed diagrams and clear explanations. This book focuses on those aspects of astronomy that are essential for a complete understanding of astro navigation - a must for sailors, navigators, nautical colleges and navigation tutors. Teachers and students of many other subjects including geography and mathematics will also find this book interesting, entertaining and very informative. The only book of its kind! The final book of the 'Astro Navigation Demystified' trilogy, Author's preface: Astronomy is a vast and complex subject and when I was taught astro navigation, I often wished my tutor would 'cut to the chase' and focus on only those aspects of astronomy that were relevant. When I taught navigation myself, I searched high and low for an astronomy book that would allow me to pick out just those topics that I needed to teach my students but I was never able to find one. For many years, I meant to write such a book myself to help other astro navigation tutors and students and now, at last, I have found time to do so.

This latest addition to the 'Astro Navigation Demystified' family focuses on the mathematical principles upon which astro navigation is based and will appeal to anyone with an interest in these subjects. It's aims are not only to demonstrate the application of mathematics to astro navigation but also to provide a system of navigation which could be used in circumstances where navigators are faced with problems caused by failure of satellite navigation systems or even in 'survival at sea' situations.Few navigation books describe techniques that involve first principles; instead they mostly describe methods which rely upon the use of tables of computed data and rote-learned procedures. There is obviously very little educational value in such techniques; far better that students of the subject should be helped to discover and apply the underlying principles for themselves. Accordingly, the approach adopted in this book involves putting the student in the place of a navigator who has no automated navigation equipment, chronometer or 'Sat. Nav.' and who must therefore discover a means of navigating without them. To this end, readers are guided through a method of calculating a position on the earth's surface by the application of spherical trigonometry without reliance upon equipment other than a sextant and a nautical almanac.

Reeds Astro Navigation Tables is an established book of annual astro-navigation tables compiled specifically for the needs of yachtsmen. It contains all the information the ocean-going sailor needs (without the bulk) in order to navigate by the sun, moon, planets and stars, using tables devised by practical ocean navigators. This book, together with a sextant, will enable sailors to navigate confidently and safely when out of the sight of land. The book continues to feature the well-received additions of the past couple of years, including forms to help determine True Altitude (for the sun, planets and stars), Calculated Altitude (using the versine formula) and Azimuth (using the ABC Tables), as well as a pro forma for calculating Intercept. With 8 extra pages and an improved layout, there is plenty of space for making notes and calculations.
