The JDZT340E three-axis inertial navigation system test turntable consists of two main parts: a mechanical platform and a measurement and control system. The platform adopts a U-O-O or U-O-T structural form and a precision mechanical shaft system, with a high stiffness platform structure. The main functions include position, velocity, and low-frequency oscillation motion, providing accurate single axis, dual axis, or three-axis positioning and velocity reference for the tested unit, used for static testing and calibration of inertial components and inertial navigation systems.
