DET-350A small dual-axis motorized rotary table consists of two major parts: mechanical table body and measurement and control system. It adopts U-T structural form and precision mechanical axis system with position, rate and low-frequency sinusoidal swing motion, which can provide accurate horizontal and positional benchmarks for the loads to be measured; it provides single-axis and dual-axis positioning and rate benchmarks for static test and calibration of inertial system, and it supports inertial guided multi-position measurement and It supports multi-position measurement and rate detection of inertial guide, and the accuracy of inertial guide attitude test is 0.06°.
