The Sextant

A sextant is a navigational tool used by sailors to determine their position at sea by measuring the angle between a celestial object, like the sun or a star, and the horizon. By recording this angle and knowing the time, navigators can consult star charts or tables to calculate their latitude and longitude. The sextant's precise mirror system allows for accurate angle readings, essential for safe ocean navigation before GPS technology. It remains a valuable instrument for understanding traditional navigation techniques and for backup in modern maritime practices.
