| The simulation system complied with HLA is distributed and consists of not only one federate. While designing a federation, the following must be considered carefully: How many federates consist of the federation? What functionalities each federate will be responsible for? Is each federate implemented by modifying the legacy simulation or developing new one? Is each federate a virtual simulation, constructive simulation or live simulation? How to transfer the object attribute ownership between federates? This dissertation studies above typical issues while designing a HLA federation with some examples.The paper finished the design on the satellite passing data analysis simulation system based on HLA by combining with the research on the project of the satellite passing data analysis. The design constructed a simulated environment including three federates and did some applied researches on simulation in base of this environment. The main achievements and new points of the thesis conclude as follows:1, Analyzing integrated the development of DIS in china, and finishing the design of the satellite passing data analysis system. It also gave a reference federation model of the satellite passing data analysis simulation application;2, By using a tool named KD-RTI, it constructed this simulation system based on HLA, and realized the simulating function of the system in the condition of local net;3, It realized the output of the satellite data report in STK by connecting the output module of STK with RTI, and makes the whole federation run synchronically;4, In allusion to the magnitude calculation module of the satellite at present, it realizes initially the dating calculation of the exact size of the magnitude when the satellite passes territory;5, It finished the data-writing, data-keeping and data-analyzing when the satellite pass territory simulate, it also concluded a reference data-analyzing report for the operators according to the outcome of the analysis. |
