Author Description

The Textbook on Navigation and Nautical Astronomy, written by James Gill and originally published in 1918, is a comprehensive guide to the principles and practices of navigation at sea. The book covers a wide range of topics, including the use of nautical charts, the measurement of distances and bearings, the calculation of latitude and longitude, and the use of celestial bodies such as the sun, moon, and stars for navigation. The book is divided into several sections, each of which covers a different aspect of navigation. The first section provides an introduction to the basic principles of navigation, including the use of charts and the measurement of angles. The second section focuses on the use of the sextant, a critical tool for celestial navigation. The third section covers the use of the sun for navigation, including the calculation of latitude and longitude using the sun's altitude and the time of day. The fourth section covers the use of the moon and stars for navigation, including the calculation of latitude and longitude using lunar and stellar observations. Throughout the book, Gill provides detailed explanations of the various techniques and methods used in navigation, as well as numerous examples and practice problems to help readers master the material. The book also includes numerous illustrations and diagrams to help readers visualize the concepts being discussed. Overall, the Textbook on Navigation and Nautical Astronomy is an invaluable resource for anyone interested in navigation, whether they are professional mariners, amateur sailors, or simply enthusiasts of the art and science of navigation.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
