| Abstract: | To improve the reusability and scalability of the space mission simulation system,heterogeneous runtime infrastructure(RTI) interconnection method is adopted,so the federates constructed in previous mission simulations is reused.Through the analysis of the key techniques of high level architecture(HLA) applied in this system,and also based on the concepts of bridge federate and heterogeneous RTIs,an application is designed and implemented to connect federates of different RTIs in order to make this system flexible.Then,the time advance velocity is tested and the result proves that the bridge is qualified for use. |
