what does aastrolabe
An astrolabe is a historical astronomical instrument used by astronomers, navigators, and astrologers. Its many uses include locating and predicting the positions of the Sun, Moon, planets, and stars, determining local time given local latitude and vice-versa. There is often confusion between the astrolabe and the mariner's astrolabe. While the astrolabe could be useful for determining latitude on land, it was an awkward instrument for use on the heaving deck of a ship or in wind. The mariner's astrolabe was developed to address these issues. The mariner's astrolabe, also known as a sea astrolabe, was used to determine the latitude of a ship at sea by measuring the sun's noon altitude (declination) or the meridian altitude of a star of a known declination.

a sailor uses an astrolabe by using it to tell latitude
An astrolabe helped sailors because it could determine any direction based on the position of the stars. This is why the astrolabe helped sailors.
