2025年9月3日As an important testing equipment in aerospace engineering, high-precision turntables are mainly used for satellite camera parameter calibration. The high-precision one-dimensional turntable developed has a maximum load-bearing capacity of 150kg and an angle measurement accuracy of better than ± 0.3 “. It has high repeatability positioning accuracy and precision maintenance capability, ensuring the continuous operation of the turntable and meeting the calibration requirements of high-resolution, large-diameter, and long focal length satellite cameras.
