This is the essential yearly reference work for celestial navigation at sea using a marine sextant. It is carried on every ship of the Royal Navy and on many sea-going vessels around the world. It is also at the core of celestial navigation training courses worldwide.
The Nautical Almanac contains tabulations of the Sun, Moon, navigational planets and stars for use in the determination of position at sea from sextant observations. In addition, it gives times of sunrise, sunset, twilights, moonrise and moonset, phases of the Moon and eclipses of the Sun and Moon for use in the planning of observations. All the necessary interpolation and altitude correction tables are provided as well as pole star tables and diagrams and notes for the identification of stars and planets. Information on standard times for most countries around the world is provided. A concise set sight reduction tables and sight reduction form are also included.
