The development of a large singlegimbal control momentum gyro(CMG)for the space station developed by the Beijing Institute of Control Engineering(BICE)has entered a new phase.The next-generation CMG product with the largest output torque and the most complicated structure in China is under commissioning.Once being put into operation,it can meet the requirements of attitude control for large spacecraft and The development of a large singlegimbal control momentum gyro (CMG) for the space station developed by the Beijing Institute of Control Engineering (BICE) has entered a new phase.
