Measuring instruments are the third party standards required for measuring in order to obtain some attribute values of the target. Measuring instruments generally have scales, volumes and other units. Scholars and navigators know very well that if the position of celestial bodies can be accurately measured on the sea, then sailors can know their latitude with certainty. To do this, we need precise measuring instruments. Ptolemy once described the astrolabe (also called the astrometer). The larger ones are used in observatories and the smaller ones are used on ships. The use of the astrolabe requires the cooperation of three people - one holds the thumb ring on the astrolabe, one aims, and the other reads the results on the dial. When the ship shakes violently.
