This book was released on 2018-10-04 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starpath work forms for sight reduction procedures in celestial navigation have been used by tens of thousands of navigators for over forty years. Designed to make the sight reduction of all celestial bodies flow in the same logical procedure that matches how data are presented in the Nautical Almanac and in the various sight reduction tables. There is always a place for adjusting angles to base values as needed, plus reminders on the signs of the values. Intermediate results are grouped for convenient entrance to the tables and for plotting the resulting lines of position. Once a few examples have been worked, the forms alone guide you through the process. Even after being away from cel nav for long periods, the forms are a quick refresher that gets you back up to speed quickly. Detailed instructions are included, with warnings about common errors. Forms included are: Form 104 -- Sight reduction of all bodies using Pub 249 (Vols. 2 and 3) or Pub 229 (all volumes). The workhorse of the Starpath approach to celestial navigation Form 111 -- Sight Reduction of stars using Pub 249 Vol.1 Selected Stars. Form 106 -- Sight reduction of all bodies using the NAO Sight Reduction Tables included in the Nautical Almanac. This form is a unique tool that makes these tables (that every navigator has) as easy to use as any other method. Form 108 -- A combination of Form 104 and Form 106 for those who choose the NAO Tables as standard, Form 109 -- For completing multiple solar index corrections and averaging them. This is a high-accuracy method, praised since the formative days of celestial navigation in the late 1700s, but not used as often as it could be these days. Forms 107, 110, and 117 cover latitude and longitude at noon as well as latitude by Polaris. These are basic procedures, but many new to cel nav find them helpful to get started... and they are instant refreshers after being away from the subjects for some time.

Book excerpt: This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.

Available in PDF, EPUB and Kindle. Book excerpt: Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: Simple Celestial is an instructional manual on the art of celestial navigation. The manual is clear, succinct and thorough in presenting in a simple style the process of observing the Sun, Moon, planets and stars used in celestial navigation in order to derive a position fix any where in the world. The process of celestial navigation as presented in the manual uses an assumed position to derive an intercept that is the basis for a line of position from the heavenly body. Additionally, the manual explains the alternate method of observing the Sun at local apparent noon for a position fix. Using either method and with the appropriate supporting tools, the student will find the manual an excellent guide in completing the sight reduction form to arrive at a solution. The manual deliberately relegates theory to a small chapter in the back, concentrating rather on the practical aspects of celestial navigation.

This book was released on 2010-05 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Celestial navigation is a way to find your latitude and longitude on earth using a sextant to measure the angular heights of celestial bodies above the horizon. It has been used by mariners at sea and explorers on land for three hundred years, and it is still used today as a dependable backup to modern electronic navigation. Routine celestial navigation relies upon accurate time (Universal Time) to find the longitude of a position (latitude does not require time). Advanced celestial navigators can find longitude without knowing the time using a technique called Lunar Distance. In this technique, the sextant is used to measure the angular (diagonal) distance between the moon and another celestial body. Since this distance slowly changes as the moon moves eastward though the stars, it can be used to find the time of day that is needed to complete the longitude determination. The process of finding longitude from lunar distance, however, requires special tables that have not been published in the Nautical Almanac or other sources since the early 1900s. Although software solutions have been available, most advanced celestial navigators are very grateful to navigation historian Bruce Stark for creating these printed tables dedicated to this task. They have been used and tested by mariners for more than 15 years and are praised by experts for their ingenuity and ease of use in solving this complex navigation exercise-which all agree is the hallmark of an expert celestial navigator. With The Stark Tables in your nav station, you no longer have to fear losing power to your electronic navigation aids, nor are you dependent on accurate time from any official broadcast. Besides their practical use in back up navigation, historians have used these tables for years to interpret the logbooks of Lewis and Clark, David Thompson, James Cook, Matthew Flinders, George Vancouver, Nathaniel Bowditch, and other notable explorers and sea captains. "It is remarkable in this day when the very survival of celestial navigation seems in question, that an individual should suddenly appear on the scene and present to the world such a brilliant piece of work. Stark has rendered a great service to the celestial navigation community." - Robert Eno, The Navigator's Newsletter "Captain Cook would have relished using these tables, had they been available to him then." - George Huxtable, FRIN

Available in PDF, EPUB and Kindle. Book excerpt: The 12th edition of this bestselling book is proof of the success of Mary Blewitt's concise and clear style in explaining a particularly difficult skill, and it has been the bible for many generations of ocean navigators. Since this book was first published, the huge advances in electronic navigation have transported most offshore navigators to a world of press-button convenience. However, there is still a vital need for traditional skills when things go wrong: batteries can fail, aerials go overboard, and electronics have been known to get wet. A bestseller for over 50 years, Celestial Navigation for Yachtsmen is a model of simplicity and clarity. The worked examples require only straightforward addition and subtraction, which explains why this book has truly earned its reputation for admirable conciseness and for making a tricky subject easy to understand.
