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 รขโ‚ฌยฆ The sextant is a navigational instrument used to measure angles.

With the sextant, sailors could measure the angle of stars above the horizon, allowing them to determine their position more accurately than ever before. The introduction of the sextant facilitated longer sea รขโ‚ฌยฆ Learn the art of celestial navigation with a marine sextant. Learn its history, components, and techniques for accurate, navigation. Navigators used sextants to measure the angle between a visible object, like the sun or a star, and the horizon. Using mirrors and a scale, the sextant provided navigators with precise measurements that รขโ‚ฌยฆ 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.
