Application of HLA time management in space mission simulation framework

Aiming at applying time synchronization and data interaction between components of space mission simulation framework, a time synchronization strategy was designed based on high level architecture (HLA). The strategy achieved a self-adjusted selection of time steps by using event driven simulation technology, and compounded different time advancing services to achieve logical time synchronization and simulation data interaction between federates. Analysis shows that this strategy unifies the time management across the components within the framework, realizes compatibility of components across federation, and improves the reusability of components. The strategy satisfies the space mission simulation framework effectively, and also can be used as an example of time management for other similar analysis simulation systems.
