Celestial Navigation When Your GPS Fails is about finding position at sea from the Sun, Moon, planets or stars. If you have a sextant and the time, in both senses, this book contains all you need to find your position. This book is for real and aspiring bluewater sailors; those who leave the sight of land and rely on various electronic devices for navigation. When satellite navigation fails because of seawater in the electronics or just plain battery failure then being lost at sea is a life-threatening situation, especially when night falls. Everything you need is here, apart from the sextant and a watch. A calculator is handy but not essential. There is complete instruction on how to use a sextant, on making astronomical observations and on how to do the calculations with or without the forms. All tables and the forms needed to make the calculations are available. You do not need any further almanacs or tables for the next ten years! The text explains the celestial framework in which we must operate, with particular reference to the way that the Sun, Moon stars and planets appear and the principles of astronomical navigation. The sextant is described along with its errors and the necessary corrections that need to be applied. Reductions of observations for dip, refraction, semi-diameter of bodies and parallax are covered. With the theory well established, the practicalities of position finding are explained in detail. There is a chapter on the origins of some of the formulae used for those who want a deeper understanding of the mathematics involved but this may be omitted by those who prefer to focus more on the practice of position finding. The main text concludes with a detailed worked example and blank forms for your own observations of celestial bodies and for the calculation of position. All the tables that you will need are included. All the other tables that you might need, depending on when and where you are going, are on the Celestial Navigation website.

Traditional navigation with a sextant, an almanac, and a book of tables is still thriving, even with the availability of accurate, cheap GPS receivers. Batteries sometimes go dead, and electronic devices fail, especially in salt air. Also, it can be satisfying and fun to work out a position and plot it, all on your own - but getting good at it requires some practice.100 problems is a self-contained book of realistic celestial navigation problems, including excerpts of all the necessary Nautical Almanac pages and sight-reduction tables, with answers and explanations.

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.

With just four required items: 1-This all inclusive book (with simple terms, teaches you how to use a sextant/navigate and includes all celestial data needed till the year 2056), 2-sextant, 3-compass and 4-universal time (shortwave radio or time piece) you can navigate the globe by using latitude and longitude derived from the sun with these four items and have peace of mind knowing that you have a reliable backup to GPS. Once you have your position in latitude and longitude, this book teaches you basic navigation (destination, heading and distance), so you will never be lost.For safety reasons and because equipment fails, batteries die, and equipment falls overboard, people going to sea should have at least two different methods of navigation. The preferred primary method is using a GPS system. This book will teach a secondary backup method of my version of the "Noon Shot Fix".If you are headed offshore, just curious about celestial navigation or have an old sextant and wonder how it works, buy this book with the other required items and you won't be disappointed. This book can be read in a short amount of time with sextant readings starting immediately. This book is a combination of basic theory, teaching only what you need for a noon shot fix and basic navigation/plotting, along with a checklist type form to calculate your position, all inclusive celestial data, many "completed" examples and information on emergency navigation.There are many other great celestial navigation techniques out there that people use every day, however many of these techniques require more dedication to learn/use. My goal was to create a simple book, that could be used by the average person with no background on the subject, and contain all the information needed that could be called on in a time of emergency. Anyone with basic math skills can learn/use this technique.

Driving down the glamorous Las Vegas Strip, Bryce Hartman is plotting revenge against his former boss, the powerful governor of Nevada. Three thousand miles away, in Washington, D.C., Peter Holden, a two-bit lobbyist, will soon be doing the same. Long silenced by Governor Logan Key, they alone suspect the dark secret he hides, one that threatens a multimillionaire Las Vegas casino baron who will stop at nothing to protect his interests. When Albert Tom, a young Paiute Indian, discovers a body in the desert, he tells his story to reporter Mike Stanton. Now Stanton must uncover a web of deceit and murder stretching from Las Vegas to Washington, two cities where power, greed and illusion are the real games of chance.

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.

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.
