The three-axis simulation turntable consists of two main parts: the mechanical turntable body and the measurement and control system. The turntable adopts a U-O-O or U-U-T structure, a precision mechanical axis system, and a high-rigidity platform structure. It has simulation, position, rate, and swing functions, and can simulate the three-dimensional motion of a load. It is used in ground-based semi-physical simulation systems to provide a near-realistic motion environment for loads such as inertial navigation systems. It can also provide single-axis, dual-axis, or three-axis positioning and rate references for the load under test, and is used for testing and experimentation of inertial components, assemblies, and inertial navigation systems.
