Description

technical field [0001] The invention relates to a high-precision and miniaturized dual-axis rotating bidirectional locking and positioning device, in particular to a biaxial rotating and bidirectional locking and positioning device used for an inertial measurement device, and belongs to the field of locking and positioning. Background technique [0002] The function of the inertial measurement device is to provide relevant motion parameters and motion instructions for the real-time measurement of the moving carrier, and to control the moving carrier to achieve the movement of the expected trajectory. Because of its high requirements for the installation and use environment, it is mostly installed inside the moving carrier, but the inertial measurement The characteristics of the device require that it needs to be inspected, calibrated and maintained from time to time, but the installation location and environment make the use and maintenance process cumbersome and costly. In ...
