Don't leave shore without this easy-to-use celestial favorite navigation primer--it could save your life! Huge advances in electronic navigation since the original publication of  Celestial Navigation  have transported offshore navigators to a world of press-button convenience. Traditional navigation skills--and technology-free position finding--are still vital, though, especially when things go wrong, as they will: batteries fail, antennas go overboard, and electronics get wet. Knowledge of celestial navigation is a life-saving emergency skill; it is also a rite of initiation and its practice still a favorite pastime among...

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...

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...

Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. ÿ In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from...

Praised by The Practical Sailor as "a first-class piece of work," Susan P. Howell's Practical Celestial Navigation was developed for Mystic Seaport's navigation courses. This third edition, originally published by the Seaport's Planetarium, retains the step-by-step format of the original, along with an abundance of diagrams and practice problems. Practical Celestial Navigation is recommended as a self-instruction text for beginners or for old celestial hands getting back in practice.
