The primary use of a sextant is to determine the angle between an astronomical 

object and the horizon for the purposes of celestial navigation. 

The determination of this angle, the altitude, is known as sighting 

(or shooting) the object, or taking a sight. The angle, and the time 

when it was measured, can be used to calculate a position line on a 

nautical or aeronautical chart. 

Common uses of the sextant include sighting the sun at solar noon or Polaris at night 

(in the Northern Hemisphere) to determine latitude. Sighting the height of a landmark 

can give a measure of distance off and, held horizontally, a sextant can measure angles 

between objects for a position on a chart.[1] A sextant can also be used to measure the 

lunar distance between the moon and another celestial object (such as a star or planet) 

in order to determine Greenwich Mean Time and hence longitude.
