It consists of a graduated arc of 60 degrees, a sighting mechanism, and two mirrors that reflect the image of the celestial object and the horizon onto the arc. By aligning the two images and reading the angle on the arc, a navigator can determine their position on the Earth with great accuracy. The sextant was developed in the 18th century and replaced earlier navigation instruments such as the quadrant and the astrolabe. It remains an important tool for navigation at sea and in aviation, although it has largely been replaced by electronic devices such as GPS in many applications.
