Study of Distributed Virtual Test System Based on HLA

According to the long simulation time and bad expansibility of traditional virtual test system, a new virtual test system based on HLA (High Level Architecture) was developed. The composition of general purpose ATS (Automatic Test System) and it’s working environment were introduced, the federates of the virtual test system was proposed, the FEDEP (Federation Development and Execute Process) of the virtual test system was proposed, the FOM (Federation Object Model) and SOM (Simulation Object Model) of the federation was developed, and the simulation flow of the virtual test system was shown.
