Here's how it works:
* Measuring the angle: The sextant measures the angle between the sun (or another celestial body) and the horizon.
* Knowing the time: The sailor also needs to know the exact time (usually using a chronometer).
* Using nautical tables: This angle and time information are then used with nautical tables to calculate the latitude and longitude of the ship.
Other details:
* The sextant uses a mirror to reflect the image of the sun onto a scale.
* It's a precise instrument that requires skill and practice to use effectively.
* While GPS has largely replaced the sextant for modern navigation, it's still a valuable tool for celestial navigation and a vital part of maritime history.
