Navigating seafarers. in order to ascertain the height in degrees of the Sun above the Horizon at 12 noon.
They are still used today , in ships that do not have electronic navigation aids.
All navigating seafarers are trained to use a sextant in case of any breakdown in electronic gear on a ship.
The sextant was developed in the 18th century, with significant contributions from several inventors. The first practical sextant is attributed to British instrument maker John Hadley, who created a working model around 1730. However, the design was also influenced by earlier navigational instruments such as the quadrant and the astrolabe. The sextant became widely used by sailors for celestial navigation, allowing them to measure the angle between a celestial body and the horizon.
The horizon shades on a sextant are used to block out excess light from the sun or other bright sources on the horizon, making it easier to take accurate measurements of celestial objects such as stars or planets. They help to reduce glare and improve visibility when using the sextant for navigation or celestial observations.
Explorers in the 1700s such as James Cook and Antoine de Bougainville used the sextant for celestial navigation during their voyages. This tool helped them determine their position at sea by measuring the angle between the horizon and a celestial body, such as the sun or stars.
A sextant is an instrument used in navigation to measure the angle between a celestial body (like the sun or a star) and the horizon. By determining this angle, along with the time of the measurement, a navigator can use trigonometry to calculate their position on the Earth's surface.
Lewis and Clark used a sextant to determine their latitude by measuring the angle between the horizon and the sun or a star. This helped them navigate and map their route across uncharted territory during their expedition to the western United States.
you use a sextant to navigate.
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. ... The angular distance of the star above the horizon is then read from the graduated arc of the sextant

The term "sextant" comes from the Latin word "sextans," meaning one-sixth. This refers to the instrument's ability to measure angles up to one-sixth of a circle (60 degrees). The sextant is commonly used in navigation to determine the altitude of celestial bodies.
