- Sextant - Wikipedia
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
- Sextant | Navigation, Celestial Measurement Astronomy | Britannica
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
- How Sextants Work: An Illustrated Guide – Casual Navigation
A sextant is a navigational instrument that measures the angle between two objects It uses a pair of mirrors to overlay one object over the other The angle between the objects is proportional to the angle between the mirrors, so you can read it directly from the arc of the sextant
- SEXTANT Definition Meaning - Merriam-Webster
The meaning of SEXTANT is an instrument for measuring angular distances used especially in navigation to observe altitudes of celestial bodies (as in ascertaining latitude and longitude)
- What is a Sextant and How Does it Work? - Orbitshub
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
- A Comprehensive Guide to Marine Sextant

- 3 Ways to Use a Sextant - wikiHow
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
- What is Sextant, its types, principle and errors - MarineGyaan
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
