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 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 precision optical instrument used primarily in maritime and celestial navigation
A sextant’s main use is to measure the angle that separates a celestial body—like the sun, moon, or stars—from the horizon 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 sextant on the other hand was made specifically for navigation and is a more accurate instrument that allows the users to find both latitude and longitude It works on a reflection principle and is easier to use compared to the astrolabe.
