[0002] The theodolite, which is usually easy to adjust, is an instrument used to measure the longitude and latitude of a point on the earth's surface. The working principle of the theodolite is based on the movement of celestial bodies and the determination of the observer's position. The observer observes the position of celestial bodies through a telescope or other device, and then records the observation results. Based on the known laws of celestial motion and observation data, the longitude and latitude of the observed position can be calculated.
