A diagram of a typical nautical sextant, a tool used in celestial navigation to measure the angle between two objects viewed by means of its optical sight. 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 ...

These stars are typically used in two ways by the navigator. The first is to obtain a line of position by use of a sextant observation and the techniques of celestial navigation. [4] Multiple lines of position can be intersected to obtain a position known as a celestial fix.
Celestial navigation 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.
The instrument was discussed in all navigation manuals beginning in the mid-16th through the 17th century; it lost its prominent place in celestial navigation when the cross staff and the Davis quadrant gained general acceptance. According to a census of 2018 more than 100 astrolabes are preserved, most of them salvaged from wrecks.
