This turntable is a temperature controlled three-axis electric turntable, with all three axes being electric shaft systems and equipped with functions for position, speed, swing, and high/low temperature testing. The turntable is mainly composed of three parts: the mechanical platform, the temperature control box, and the measurement and control system. It is mainly used for testing and calibrating the dynamic and static parameters of the inertial navigation system within the full temperature working range, as well as for testing and calibrating the inertial navigation system at room temperature and inertial components.
