| how to use sight reduction tables: Celestial Navigation Dominique F. Prinet, 2014-07-17 This manual has grown out of all the courses given by Dominique Prinet, a certified Instructor-Evaluator for Sail Canada who has been teaching celestial navigation since 2000. It has benefitted from the thoughtful contributions of over 100 students. The aim of Celestial Navigation is to give a sufficient grounding in the subject to determine position at sea using a sextant for fixes on the sun, moon, stars and planets. Furthermore, the material presented will prepare a reader who wishes to pursue a Celestial Navigation Certificate through self-study. The subject requires some comfort with the basic concepts of navigation, but the prospective navigator only needs to know how to add and subtract either times or angles. Lucid and well-paced, Celestial Navigation starts with fundamentals and definitions which ensure that a motivated student need not bring anything more to the table than his or her willingness to master the subject. Richly illustrated, it includes a chapter with more than forty pages of review exercises covering all topics. The cleverness of many of the concepts, explained here, will bring about great intellectual joy and satisfaction. Whether you are a recreational sailor or an individual pursuing professional certification as a navigator, Celestial Navigation will teach you what you need to know. |
| how to use sight reduction tables: Pub 229, Sight Reduction Tables for Marine Navigation NIMA Staff, 2002 The Sight Reduction Tables for Marine Navigation (Pub 229) is published in six volumes, each of which contains two-eight degree zones of latitude with a one-degree overlap between volumes. They are designed to facilitate the practice of celestial navigation at sea. The tables are primarily used with the intercept method of sight reduction by entering arguments of latitude, declination, and local hour angle and obtaining tabulated altitudes and azimuth angles. The tables are prepared and published by NIMA on an as-needed basis. |
| how to use sight reduction tables: Celestial Navigation Exercises for Class and Home study Dominique F. Prinet, 2016-01-15 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. |

| how to use sight reduction tables: Norie's Nautical Tables John William Norie, A. George Blance, 2007-01-01 This famous set of mathematical tables was first published in 1803. It has been a bestseller ever since, and despite developments in electronic navigation it remains an essential requirement for anyone learning and practising astro-navigation. Last updated in 1994, the editor, George Blance, has worked for some time on the modernisation of all the tables for this major new edition. New tables have been included and obsolete ones deleted to conform with the changing techniques of navigation, with the aim of improving the accuracy of the calculated position and reducing the tedium of the calculation. All the tables required for coastal and deep sea navigation are included. A simple uniform method of interpolation for all the trigonometrical tables is used. Certain tables and data are also included which are not readily available on board ship or are only used in the examination room. The section 'Seaports of the World' has also been extensively updated and restructured with several hundred additional ports. The ports are listed geographically in the following order from Arctic Russia, Scandinavia, the Baltic Sea, the Atlantic coast of Europe, the Mediterranean Sea, West Africa, East Africa, Arabia, the Persian Gulf, the Indian sub-continent, the Far East, Australasia, the west coast of North and South America and finally the east coast of North and South America. At the back of the section is an index of the seaports. |

| how to use sight reduction tables: Celestial Navigation for Yachtsmen Mary Blewitt, 2013-09-21 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. 'The bible of navigation for generations of yachtsmen... worth its weight in gold' Sailing |

Barrie takes readers straight to the helm of some of history's most important expeditions, interweaving these heroic tales with the account of his own transatlantic passage as a young man. A heady mix of adventure, science, mathematics, and derring-do, Sextant is infused with a sense of wonder and discovery. At once a dramatic history of maritime endeavor and a love letter to the sea and sky, it is timeless storytelling at its best. |

| how to use sight reduction tables: Celestial Navigation Bruce Steely, 2020-06-24 Celestial navigation can be a daunting and intimidating subject for some to learn. There are many comprehensive books on the subject which I recommend, but the beginning student can be overwhelmed by the vast amount of information in these texts. To initially learn celestial navigation, sometimes less is more. By clearing a path through the esoteric details and providing just enough information with concise explanations, simple visual aids and examples, learning celestial navigation becomes easier and more enjoyable. The goal of this booklet is to serve as a launch pad into the subject which may be all that many yachtsmen need. For those who want to learn more, this booklet will prepare you for more in-depth studies. Includes full-color 3-D illustrations. Forward by John Kretschmer |

| how to use sight reduction tables: Celestial Navigation in the GPS Age John Karl, 2007 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. |
