These tables were designed for air navigation where weight and space are at a premium, however, they are very popular with sailors too due to the fact that Vol. 1 offers a speedier way to compute stars. Volume 1 contains some stars (whose declinations may be more than 29°) that are pre-selected for optimum viewing and direction. This volume is applicable for an 8 year period, centered on its Epoch date.
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.
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.
In the tradition of Dava Sobel's Longitude comes sailing expert David Barrie's compelling and dramatic tale of invention and discovery—an eloquent elegy to one of the most important navigational instruments ever created, and the daring mariners who used it to explore, conquer, and map the world. Since its invention in 1759, a mariner's most prized possession has been the sextant. A navigation tool that measures the angle between a celestial object and the horizon, the sextant allowed sailors to pinpoint their exact location at sea. David Barrie chronicles the sextant's development and shows how it not only saved the lives of navigators in wild and dangerous seas, but played a pivotal role in their ability to map the globe. He synthesizes centuries of seafaring history and the daring sailors who have become legend, including James Cook, Matthew Flinders, Robert Fitz-Roy, Frank Worsley of the Endurance, and Joshua Slocum, the redoubtable old "lunarian" and first single-handed-round-the-world yachtsman. He also recounts his own maiden voyage, and insights gleaned from his experiences as a practiced seaman and navigator. Full of heroism, danger, and excitement, told with an infectious sense of wonder, Sextant offers a new look at a masterful achievement that changed the course of history.
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.
This edition of this this flight stability and controls guide features an unintimidating math level, full coverage of terminology, and expanded discussions of classical to modern control theory and autopilot designs. Extensive examples, problems, and historical notes, make this concise book a vital addition to the engineer's library.
