The improvement of the mission capability of spacecraft has made it more demanding for the in-depth, intensive design of satellite system. It is required that the ultimate goal of system performance to be carried out around the mission capability, which in turn will lead to significant changes in product integration and verification models. This paper introduces the development and application of the multi-discipline integrated development model for spacecraft, analyzes the needs and implications of integrated design, and introduces the implementation and exploratory applications of the multidisciplinary integrated collaborative platform.
