The Design and Implementation of Spacecraft Co-simulation Platform

With the continuous improvement of complexity in the space simulation system and the enhancement of multi-technology integration, the co-simulation technology is an important way to solve complex simulation problems in the big system. After analysis of relative theories and main methods of co-simulation, collaboration data interfaces among multiple software are improved and matched with a number of simulation software system. The co-simulation framework is designed and a set of spacecraft dynamics co-simulation analysis system is established on the frame of HLA/RTI and on the principle of co-simulation technology. The key task on orbit service of the spacecraft is modeled and simulated. The software can complete the work that a single simulation software could not be done and achieve good results.
