KSAT2 is a nano-satellite developed by Kagoshima Satellite Development Team. KSAT2 will be launched as one of the piggyback satellites of GPM, which is developed by NASA. Since the thermal environment in space is very harsh, the thermal design of the satellite is necessary in order to control the temperature of electric devices installed in the satellite within the allowable limits. In this study, we will clarify the attitude of the hottest and coldest conditions, and decide the most suitable surface finish method of the KSAT2. The authors performed a steady state analysis in various attitude of simplified KSAT2 model. As a result, we obtained the thermal worst condition and attitude of KSAT2.Furthermore we found that the best surface finish method is no-treatment for outer panels and black alumite coating for the two paddles.
