With the development of technology, it is very important to measure the parameter of angle. This paper gives an introduction of basic principle of Non-gyro Inertial Measurement Unit. According to the theory of geostatics, Arithmetic and basic principles of NGIMU are given. In describing the movement of rigid body, we suppose an inertial frame and revolving frame, the expression of angle acceleration is given by the arrangement of linear acceleration. The application of arithmetic and basic principles is given in the paper, calculating the single angle acceleration by three linear acceleration and processing the signal through analog filter, amplifier and digital filter, then discussing the possible problem in practicality.
