celestial navigation

A form of navigation where the known position of celestial bodies and their angle to the observer, along with the time of the observation, are used to determine position. The exact position of stars is given in a nautical or aeronautical almanac. This form of navigation has been almost entirely replaced by various forms of electronic navigation.
