Late 16th century (denoting the sixth part of a circle)

A sextant 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 estimation of this angle, the altitude, is known as sighting or shooting the object, or taking a sight A sextant is a navigation instrument used to measure the angles between celestial bodies and the horizon It works by aligning the index mirror with the celestial body and reflecting its image onto the horizon mirror. 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

The device consists of an arc of a circle, marked off in degrees, and a movable radial arm pivoted at the centre of the circle A telescope, mounted rigidly to the framework, is lined up with the horizon. 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 You can then use that. A sextant is a doubly reflecting navigation instrument used to measure altitude or the angle between any two visible objects

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

60° but it can measure angles upto 120° using double reflection principle Nautical sextant nautical sextant, also called as vernier sextant or marine sextant, is an instrument mainly used to determine latitude and longitude by measuring angles between two objects Celestial objects such as sun, moon, and stars are sighted using a nautical sextant, and angular measurements between them and the horizon can be.
