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. 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 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 Learn the art of celestial navigation with a marine sextant Learn its history, components, and techniques for accurate, navigation. 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.
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. The lower pictures showing a range of prices are past sales of fine quality used sextants* from 2003 present and are only there for historical reference We have a detailed listing of most items. A sextant is an instrument used for measuring the angle between two visible objects Both horizontal and vertical angles can be measured using a sextant

In celestial navigation, it measures the angle between the horizon and a celestial body (the sun, moon, planets or stars), and in terrestrial navigation, it measures the angle between two charted objects (lighthouses, piers, etc.). How to use a sextant on land to use a sextant on land, you either need an artificial horizon or a bubble sextant At sea, we can use the horizon, but on land, we need to simulate the horizon instead A bubble sextant works on the same principle as a spirit level. Sextants are commonly used in marine navigation and aviation A sextant is a valuable instrument used to determine the angle between the horizon and a celestial body like the sun, moon, or star
It is used in celestial navigation to calculate latitude and longitude. Experienced skipper wavy explains the many functions of a sextant and how to use it out on sea Join our upcoming sailing adventures to brush up on our celestial navigation skills. A sextant is an instrument generally used to measure the altitude of a celestial object above the horizon Making this measurement is known as sighting the object, shooting the object, or taking a sight A sextant is an instrument to measure a celestial object's altitude above the horizon
