I am throughly enjoying working through the wonderful book, ‘Astro Navigation Demystified’. Devised by Jack Case HOME.

A wealth of information on the subject of astro navigation can be found under the various headings on the menu bar at the top of the page and in the archives listed down the right. I am throughly enjoying working through the wonderful book, ‘Astro Navigation Demystified’. At last a well written book on the subject.

Astro Navigation Demystified. Navigate Without GPS. Skip to content. The ‘Where To Look’ Method. Devised by Jack Case In part 1 of this series, we discussed how we can establish whether or not a selected star or planet will be visible during nautical twilight. In this post, we discuss.

Astro Navigation Demystified. The ultimate book of the series; it is a complete course in astro / celestial navigation. This unique self-teach course comprehensively covers all relevant elements of the examination syllabuses of the main sailing associations. However, if you are looking for something to enable you to rote-learn only what you need to pass an exam without real understanding, then sorry, this is not the book for you; if, on the other hand, you want a book that will not only help you to pass exams but also teach you to navigate and to understand what you are doing, then you have come to the right place. Part one ranges from simple explanations of the basic principles through to detailed expositions of the important aspects of the subject. Part two provides a comprehensive coverage of the use of rapid sight reduction techniques for position fixing. Although it is a large book (containing 324, letter size pages) it is thoroughly cross-referenced and the language style used allows the text to flow smoothly from beginning to end so that it makes enjoyable reading. It is emphasised that this book teaches the rapid reduction method of astro navigation. If you wish to learn how to use the traditional method which involves the application of spherical trigonometry, then you may prefer 'Celestial Navigation - The Ultimate Course' which forms part of the series. Other books in the Astro Navigation Demystified Series: Applying Mathematics to Astro Navigation. This addition to the 'Astro Navigation Demystified' series focuses on the mathematical principles upon which astro navigation is based and it will appeal to anyone with an interest in these subjects whether they be navigators or mathematicians. Section two of the book, which is very popular with teachers and college lecturers, contains activities that are designed to provide opportunities to consolidate the knowledge acquired and provide ideal starting points for 'open-ended' projects. Celestial Navigation. The Ultimate Course The prime aim of this book is to teach the practical skills of celestial navigation and has been uniquely designed to teach the important skills from the outset while 'tying-in' the relevant theory as progress is made. There are numerous examples and self-test exercises which enhance the learning process and help to embed the knowledge and skills needed to practise the art of celestial navigation. The traditional method of celestial navigation involving the use of spherical trigonometry to calculate a vessel's position is comprehensively taught in this book. Note. The terms celestial navigation and astro navigation are generally regarded as synonymous. Astronomy For Astro Navigation. 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 - no other book focuses on only those aspects of astronomy that are relevant to astro navigation. An ideal introduction to both astronomy and astro navigation containing 178 letter size pages packed with illustrations, detailed diagrams and clear explanations. “Know the stars and you will always have a compass” (The Revenant) The Astro Navigation Demystified website provides a free resource for all those interested in the subject of astro navigation (or celestial navigation as it is also known):
  • MilsoN
This is the best book on celestrial navigation I've found so far. I'm currently about 25% through the book.
I really like the format of... explanation, example, self test. There are a lot of new concepts and terms (to me)
in this study and I often find, while taking the self test at the end of each chapter, that I didn't understand something
as well as I thought I did so I go back and review and retest. Another feature I like is the appendix with explanations
of trig formulas that are used in the chapters. You don't need how the formulas were derived to understand the material
in the chapters but if you're into math and want to know how they were derived- It's there. Shipping and all that stuff
was fine. Not sure why I didn't give it 5 stars. Probably has more to do with me than the book.
  • Tisicai
I have a taste for mathematics in general, studied civil engineering at university, and looked upon astro-navigation as a short-term challenge that I'd like to have a reasonably good understanding of. I'm not a sailor or navigator, and have no friends who have this background. I just have an interest in applied mathematics, and this book helped me achieve my goal. Jack Case really does see things from a student's perspective in his explanations of abstract, mathematical, or physical concepts. He outlines the theory, then gives examples and test questions (both with full solutions). Having completed the book I will complement it with one or two more, but this will probably remain my reference point. I highly recommend it.
  • Danial
Well written
  • Waiso
I have been using celestial navigation for 40 years, and I am in awe and love with it. This book, plus it's companion book are wonderful primers to give to novices, as well as great reminders ones' own forgetfulness.
  • Hǻrley Quinn
Very interesting though maybe just a bit much if your learning nav by rote
  • Qutalan
Easy read; but for the complete novice there is a lot of terminology that must be understood.
Let me give you a little background about me. I haven't done geometry or trig since high school; where I got good grades with challenging teachers. This book may "demystify" but it is not a quick read by any means. I won't say I gave up, but let's say I put it down after about 60 pages. I do not mind theory, or doing the homework, but it is there in spades.
Very difficult to follow explanations of dirt simple concepts. A lot of unnecessary trig diagrams using his own designations which are not standard in c-nav adding to the confusion.

The number one underlying basic premis of circles of position glossed over until late in the text and then presented in confusing math-speak. A new student probably wouldn't pick up the concept at all since it was so buried and obfuscated. Very poor explanation of equation of time and its use making me think he doesn't really understand it himself. Also poor explanation of Assumed Position seeming to indicate he has an unusual grasp on that concept as well. Made a mess of parallax, I couldn't follow him at all on that simple but important concept.
Your head will spin trying to follow his spherical trig explanations where simple common sense explanations will do.
What I bothered to unravel was correct, so that is better than some books on the subject, but definately the hard way to learn. I've got a pretty good grip in this subject but even stuff I know cold was made impossible to follow such as latitude by meridian sight of sun or calculating local hour angles.

Two stars because it isn't flat out wrong which some books on this subject are.

skip this one unless you are an applied math type. One reviewer who IS an applied math type and NOT a navigator liked this book very much. Fair enough.

This book takes simple concepts and makes them difficult and confusing. On the other hand If you want to discourage people from asking you to teach them c-nav, this is the book to give them. They won't come back to bother you again.
