Designing spacecraft TT&C simulation system based on HLA

This paper presents the application of The high level architecture (HLA) of distributed and interactive simulation technology } to Spacecraft TT&C simulation system. It developes the architecture of Spacecraft TT&C simulation and defines the federates, in order to improve the reusability of components and extensibility of the simulation system. Meanwhile, this paper introduces the design and realization of federation object model(FOM), simulation object simulation model(SOM) and View federates prodecure framework.
