A thermal mathmatical model plays an important role in operations on orbit as well as spacecraft thermal designs. The thermal mathematical model has some uncertain thermal characteristic parameters, such as thermal contact resistances between components, effective emittances of multilayer insulation (MLI) blankets, dscouraging make up efficiency and accuracy of the model. This paper presents a new parameter estimation method for spacecraft thermal mathematical models in order to streamline model creation and to realize high accurate models, by using a particle filter which is one of successive data assimilation methods, which can create a fusion of numerical simulation and observation data.
