The method of developing distributed interactive simulation application systems based on HLA is analyzed. The whole framework of air force station simulation system is introduced. Based on modeling tools Labworks, PRTI, MultiGen Grreator, Vega and VC + +, the air force station simulation system is realized. Each function unit of visual simulation system is laid out, and the working flow of visual simulation system is illuminated in detail. The result validates the feasibility and validity of this method.
