The JDZT240H two-axis testing turntable consists of two main parts: a mechanical platform and a measurement and control system. The platform adopts a U-T structure and a precision mechanical axis system, with position, speed, and low-frequency sine swing motion functions. It can provide accurate single axis and dual axis positioning and rate reference for the tested load, and is used for static testing and calibration of inertial components and inertial navigation systems.
