  1. Sextant

    A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the object's altitude. Making this measurement is known as sighting the object, shooting the object, or taking a sight and it is an essential part of celestial navigation. 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 and sighting Polaris at night, to find one's 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. A sextant can also be used to measure the lunar distance between the moon and another celestial object in order to determine Greenwich time which is important because it can then be used to determine the longitude. The scale of a sextant has a length of ⅙ of a turn; hence the sextant's name. An octant is a similar device with a shorter scale, whereas a quintant and a quadrant have longer scales.

The Nuttall Encyclopedia

  1. Sextant

    an instrument used in navigation (sometimes also in land-surveying) for measuring the altitudes of celestial bodies and their angular distances; consists of a graduated brass sector, the sixth part of a circle, and an arrangement of two small mirrors and telescope; invented in 1730 by John Hadley.

Dictionary of Nautical Terms

  1. sextant

    A mathematical instrument for taking altitudes of, and measuring the angular distances between, the heavenly bodies. It is constructed on a principle similar to Hadley's quadrant; but the arc contains a sixth part of a circle, and measures angles up to 120°.

Military Dictionary and Gazetteer

  1. sextant

    An instrument of reflection for measuring angular distances between objects. It is constructed on the same optical principle as Hadley’s quadrant, but usually of metal, with a nicer graduation, telescopic sight, and its arc the sixth, and sometimes the third part of a circle.
