Abstract
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. The main purpose of this study is to confirm thermal feasibility of KSAT2. We performed the steady state analysis of simplified KSAT2 model. Then the temperature of the main body was surveyed for the thermo-optical properties, as/εH, from 0 to 2 for the hottest and coldest cases on orbital operation. The result of the present analysis reveals that the temperature of KSAT2 averaged along the orbit falls within the allowable limits.
