A sextant a sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects Learn how to use a sextant for celestial navigation with this detailed guide, covering techniques, tips, and practical insights. 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 60° but it can measure angles upto 120° using double reflection principle. A sextant is a navigational instrument used to measure angles
In celestial navigation, it measures the angle between the horizon and a celestial body (e.g
A star or a planet). In modern usage the term is applied to all modern. 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.
