Explanation: The astrolabe enables astronomers and sailors to calculate the position of the Sun and stars with respect to the horizon and the meridian.  The astrolabe can calculate the altitude and predict the position of celestial objects in time.  An astrolabe is a device that uses astral bodies like the sun and stars to either tell your position in latitude or tell the local time.
