Design and Application of SpaceSim:A Spacecraft System Simulation Software
In order to meet the great demand of domestic space system design software for Chinese space industry,SpaceSim,a spacecraft system simulation software,is designed.Facing the problem that the simulation for large-scale space systems is inefficient,the coupled simulation of advanced loads in various fields such as communication,navigation and remote sensing is complex and the traditional simulation framework is difficult to meet the requirements of time-sensitive tasks,a GPU-based multi-domain modeling and efficient simulation method for large-scale space systems is proposed.A time and event driven space system software running framework is constructed,and a high-performance co-simulation interface with third-party software is implemented.SpaceSim can complete the simulation and verification of the whole mission cycle of spacecraft design,testing,launch,operation and control,and can be widely used in project type task.
