Sextant
A sextant is a navigational instrument used to measure the angle between any two visible objects. It is commonly used in maritime navigation to determine the angle between the horizon and a celestial body such as the sun, moon, or stars. This angle, along with the time of day, can be used to calculate the ship's position on the globe. The sextant is an essential tool for celestial navigation and has been used by sailors for centuries.
