Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the surface of the Earth without relying solely on estimated positional calculations, commonly known as dead reckoning.
Publications called Nautical Almanacs give, for each hour of each day of the year, the exact coordinates of the GP of the sun, moon, major planets, and brightest stars on the celestial sphere. A straight interpolation allows the calculation of the coordinates of the main celestial bodies at any time in between (fig. 1.6).
