Abstract: The control moment gyroscope (CMG) is one of the important actuators for attitude control, and it is also the main noise source of the space station. The noise of 1000N·m·s CMG is completely tested, and the results show that the maximum noise of the 1000N·m·s CMG reaches 90.9dB. Based on the analysis of the noise testing results, the main noise sources and their action mechanism are determined, which provides the theoretical basis for the subsequent study of the denoising method.

Key words: CMG, noise test, result analysis, denoising
