Description
The Sextant is a device used by mariners to navigate the sea and solve celestial navigation problems such as finding a specific latitude or altitute on a particular atoll or island. In order to solve these problems, one must know the current position of the boat and the time their departure. These instruments are known as sextants because they let you take altitude readings very accurately. This is how they were used in order to calculate longitude in the past when accurate navigation was not possible using other navigation tools such as dead reckoning and astrolabe.
