A sextant helps navigators determine their position by measuring the angle between a celestial object, such as the sun or a star, and the horizon. By comparing this angle with known values, sailors can calculate their latitude and longitude accurately. This tool is essential for celestial navigation when GPS or other electronic systems are not available.
A sextant was a crucial tool for navigators during the Age of Exploration, allowing them to measure the angle between celestial bodies and the horizon. By determining these angles, sailors could calculate their latitude and, with additional tools, their longitude. This capability significantly improved their ability to navigate open waters, leading to more accurate mapping of the world's oceans and coastlines. Ultimately, the sextant contributed to safer and more efficient sea voyages, facilitating exploration and trade.
They wouldn't have had to depend on the stars for navigation. If the sky were cloudy, they wouldn't have been able to use a sextant. GPS and accurate maps would help them avoid obstacles.
Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
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.
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 helped explorers by allowing them to determine their latitude at sea by measuring the angle between the horizon and the sun or a star. This helped navigators plot their position on a map and accurately navigate the vast oceans.
The sextant was the instrument that aided explorers by allowing ship navigators to determine their location by measuring the angles between celestial bodies, such as stars and planets, and the horizon. This device enabled navigators to calculate their latitude and longitude, which was essential for accurate navigation on the open sea. By using the sextant in conjunction with precise timekeeping, explorers could chart their positions more effectively and embark on longer voyages with greater confidence.

Ancient mariners used tools called an astrolabe, a sextant, and a quadrant. These instruments were used in conjunction with celestial bodies, sunrises and sunsets.

To measure the altitude of the North Star (Polaris), an instrument called a sextant is commonly used. The sextant allows navigators to determine the angle between the horizon and the star, which corresponds to their latitude in the Northern Hemisphere. By measuring this angle, one can accurately ascertain their position relative to the North Star.
