Guiding a craft using one of the oldest of the mariner's arts-celestial navigation As romantic–sounding as sailing to Tahiti did centuries ago, using the sun, moon, planets, and stars to guide one's boat on the seas is enjoying a comeback. For those who do not wish to be caught short when modern technology fails on board, knowing how to chart a path with the aid of a sextant is an essential navigating skill. In Celestial Navigation, veteran yachtsman, Tom Cunliffe, reveals how any boat owner can master this seafaring technique, without complex mathematics, using his simplified approach. Readers begin with a sound foundation of basic concepts and definitions, before moving on to the hardware-the sextant and how to use it. Within a few pages, you'll be working out your latitude from a noon sight, and learning how to plot a position from observing the sun, planets, moon or stars-or wherever you may be on the world's oceans.

The Practical Guide to Celestial Navigation by Phil Somerville Pdf
THIS EBOOK EDITION IS DESIGNED TO BE EXPERIENCED ON COLOUR DEVICES The practical guide to celestial navigation - know what to do step by step, understand why you're doing it, and be confident that you can put it into practice when on board. Did you know that a person standing on the equator is effectively travelling at 900mph? And did you know that you can use this information to work out where you are in the world, to an accuracy of about 3 or 4 miles? No GPS, no computers. Just a sextant, some tables from an Almanac and the knowledge in this book. It's the only back up if the GPS goes down, so it's a matter of safety. If you want to qualify as a commercial skipper/superyacht captain you need to know how to carry out celestial navigation. And if you want to pass the RYA Ocean YachtmasterTM exam, you need to know it too. It's a major stumbling block for many sailors wanting or needing to take their next qualifications, and the other books on the market are complex and often assume some prior understanding. This book fulfils the need for a clear explanation of celestial navigation, illustrated with colour diagrams and including unique checklist sheets to enable you to repeat all those calculations you learned back at home, when you're on deck. Without overwhelming the reader with a load of theory from the off, the author breaks down what you need to do, step by step, explaining why at every point – giving the information context, and making it more interesting and memorable. He has trained students in this subject for years, and here he's able to use his experiences of what works, and what are the common pitfalls – he even includes a troubleshooting chapter near the end, going through errors commonly made, and how to spot them. The objective is that readers will finish the book not only knowing what to do, but really understanding why, and being able to make sense of it all again later (rather than just getting through and exam and finding themselves at a loss when on deck). The author also includes time-tested 'proformas' – quick reference sheets that sailors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most sailors experience when they suddenly need to put their theoretical knowledge to the test in the real world.
Celestial Navigation Exercises for Class and Home study by Dominique F. Prinet Pdf
About the Manual Celestial Navigation Exercises for Class and Home Study was designed to facilitate the work of instructors using the free PowerPoint slide presentation available at CelestialNavigationBook.com. This exercise manual, available in hard copy and in PDF format for tablets, reproduces the questions posed at regular intervals throughout the slide presentation; it provides the work-forms guiding the calculations, and the solutions. Students taking a course from an instructor who follows the slide presentation will normally have the associated course book Celestial Navigation using the Sight Reduction Tables Pub. No. 249. In order to facilitate the download process, the free version of the exercise manual (available for download from CelestialNavigationBook.com), includes neither the Almanac nor the Sight Reduction Tables required for the calculations because these tables are identical to the ones in the course book. This complete version of the exercise manual, with all the required data tables in the appendix, will thus be useful mostly to navigators who do not have the course book but wish to practice on their own, as well as to students who follow the presentation and have the course book but do not wish to download and print 140 pages of questions and answers.
Astronomy for Astro Navigation by Jack Case,Jack Case Ma Pdf
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.
