Book Description
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.

Book Description
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.

Book Description
The very words Astro navigation are often enough to send a cold shudder through even the most experienced boater. The funny thing is that although a lot of Astro jargon has an almost mystical ring about it, most of us know the 'secrets' on which the whole science of Astro navigation is based. RYA Astro Navigation Handbook is ideal for anyone new to celestial navigation, or wanting to update their Astro skills. It is not a textbook or manual – it is simply a book to enable you to 'just get on and do it'. It is the course book for anyone taking an RYA Yachtmaster Ocean Theory Course. Within the book, the reader will find a range of information on: The Sextant The Celestial Sphere The Noon Sight Morning & Afternoon Sights Planets Polaris Accessibility Screen Reader Friendly: Yes Accessibility Summary: This publication conforms to WCAG 2.0 Level AA.
