Compass, mainly used to indicate geomagnetic direction, is usually designed in the form of compass. Its structure is relatively simple, and its main components include a magnetic needle and a dial. The pointing ability of the magnetic needle can indicate the direction, while the dial can display the specific angle. Compass has been widely used in navigation, geodesy, tourism and military fields.
Compass, also known as compass, is a precision instrument used to measure direction and angle. Its main function is to measure the projection direction and angle of objects and celestial bodies on the ground, so as to determine the direction and height of the target. The structure of compass includes telescope, reticle and degree device. When in use, you need to fix it on a horizontal plane, observe the celestial body through a telescope, and read the degrees on the cross line to determine the direction. Compasses are also widely used in navigation, geodesy and military fields.
Generally speaking, the main difference between compass and compass lies in structure and usage. Compass is mainly used to indicate the direction, and its structure is relatively simple; Compass is mainly used to measure direction and angle, and its structure is relatively precise.
