Description: If you have ever tracked the North Star across the night sky or held a sextant in your hand, you can learn more from this fine new study of celestial navigation. This book is a unique, concise resource for the history of navigation techniques that began in the 1840s using the stars to steer a ship -- but are still in use today with modern GPS technology. This authoritative book from Unlimited Publishing LLC includes a complete reprint of the rare first edition Captain Thomas H. Sumner wrote in 1843 to describe his new method for finding a line upon which a ship's position rested. Also included are translations of two articles from the 1870s in which French Naval Capitaine Marcq Saint-Hilaire published his new technique for establishing position using the estimated altitude of the celestial body.
Notes: Includes bibliographical references (p. 30-31).
