Abstract�� To predicate the equilibrium temperature and simulate the heat variation influence of satellite thermal balance test more easily and correctly, a double layer lumped parameter model of the satellite equipment temperature was set up. The dynamic model had a simple nesting structure, its parameters can be reached from thermal balance test datum by using system identification method, and the temperature changes of different equipments on same satellite can be predicated and simulated separately, this can save a lot of computing works. Comparison studies show that the prediction and simulation results accord with the satellite thermal balance test results of accurately.
Keywords�� satellites   simulation   thermal balance test   temperature prediction   double layer lumped parameter model
