Celestial navigation

n. astronavigation, navigation of a ship or aircraft according to the position of celestial objects; navigation in space between celestial bodies

Celestial navigation, also known as astronavigation, is a position fixing technique that was devised to help sailors cross the featureless oceans without having to rely on dead reckoning to enable them to strike land. Celestial navigation uses angular measurements (sights) between the horizon and a common celestial object. The Sun is most often measured. Skilled navigators can use the Moon, planets or one of 57 "navigational stars" whose coordinates are tabulated in nautical almanacs.
