Издание на английском языке
This book is a compact and convenient guide to celestial navigation, designed for maritime navigation and extreme situations. It contains essential data on the positions of the sun, planets, and bright stars for 10 years into the future (2022–2031), as well as methods for determining a vessel's position using azimuths and altitudes of celestial bodies. The book describes in detail the principles of measurement, calculations, and interpolation, and provides practical algorithms for accurately determining a position without the need for multiple additional sources. Special attention is paid to planning observations, using epheremides, and minimizing errors. Suitable for both yachtsmen and specialists experienced in classical methods of marine navigation, it is especially useful in emergency situations.
