Sextant Sextanten är ett noggrant mätinstrument som används för att mäta himlakroppars höjd men kan också utnyttjas för att mäta horisontella vinklar. Namnet sextant kommer ifrån en sjättedels cirkel dvs 60gr. Till våra sextanter medföljer ett fabrikscertifikat så att man kan ta hänsyn till ev. fel.

Sextanten (ett redskap för navigation) tillverkades till sjöofficer Rudolf Nissen (1841-1891). Hans namn finns sirligt ingraverat på en mässingsbricka på lådan. Nissen var lärare i navigation på Kungliga Sjökrigsskolan och ska enligt uppgift ha använt sextanten i undervisningen.

A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.

The name comes from the Latin sextus, or “one-sixth,” for the sextant’s arc spans 60°, or one-sixth of a circle. Octants, with 45° arcs, were first used to calculate latitude. Sextants were first developed with wider arcs for calculating longitude from lunar observations, and they replaced octants by the second half of the 18th century. 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. The principle of the instrument was first implemented around 1731 by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but it was also found later in the unpublished writings of Isaac Newton (1643–1727).
