A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects In astronomy, sextants are devices depicting a sixth of a circle, used primarily for measuring the position of stars The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.
A sextant is a navigational instrument that measures the angle between two objects 60° but it can measure angles upto 120° using double reflection principle. It uses a pair of mirrors to overlay one object over the other
Sextant, instrument for determining the angle between the horizon and a celestial body such as the sun, the moon, or a star, used in celestial navigation to determine latitude and longitude. A sextant is a marine navigation instrument used to measure the angle between two objects Learn everything about sextants in this article. A sextant is an old navigational tool that measures elevation using angular distances
You can use a sextant to determine the altitude in the sky of the sun, moon, or other celestial bodies relative to the horizon. The meaning of sextant is an instrument for measuring angular distances used especially in navigation to observe altitudes of celestial bodies (as in ascertaining latitude and longitude). A sextant is a handheld optical tool that helps you find your position at sea by measuring the angle between the horizon and a celestial body, usually the sun or a bright star.

Primarily, they have been used for navigation However, the predecessor of the sextant is the astrolabe, which was used up to the end of the 18thcentury. Sextant is one of the oldest navigation instruments used by mariners, its called sextant because its arc is 1/6th of a circle i.e
