Inertial Navigation System (INS) is an autonomous navigation system,based on the principle of Newton's laws of mechanics, does not depend on external information and radiation, and can be applied in air, ground or underwater operating environments. In recent years, the great role of inertial technology has been increasingly evident in various fields, and the demand for this technology and inertial sensitive devices has developed into space, aviation, navigation, marine surveys, geological surveys, robotics and other technologies.
