Abstract: The design of simulation platform for space mission operations is investigated. The platform has the advantages of high generality and extensibility, being easy to build up new task. FMI (Functional Mockup Interface) standard is adopted to achieve integration of multisource models, and Python scripts are used to realize the task schedule. Unity3D is adopted to implement the visual display system which could display space manipulation process with high fidelity 3D virtual scenes. Configuration tool is developed to map the 3D objects in visual scene with simulation physical variables for complex space control mechanism, which greatly improves the platform's generality and extensibility. Finally a typical space operation mission of capturing an on-orbit target by deployed robotic arm is taken to demonstrate the functions of the platform.

Key words: space operation, simulation system, visual display, FMI standard
