This paper analyses and studies spacecraft AIT project argument, and puts forward argument methods and procedures suitable to spacecraft AIT according to the current status of argument and management modes in spacecraft development. At the same time, the risk management theory of NASA is introduced, analyzed as well as related theories are applied to the study of risks existing both in project argument of spacecraft AIT and throughout the argument process. After analyzing the risk management process with a specified risk as an example, we here propose the argument risk control method to decrease risks in argument of spacecraft AIT projects, to improve argument quality and to prepare a solid base for smooth implementation and completion of spacecraft development projects in future.
