Abstract

Our purpose is to improving the satellite thermal design process by developing a key technology of “satellite thermal environment uncertainty quantification”.

Reasons for using JSS2

There is no environment to perform the satellite thermal analyses of numerous samples under realistic time.

Achievements of the Year

We developed an method to create emulator for satellite thermal simulator using the Gauss process regression. The method was applied to actual satellite thermal problems, and the effectiveness was shown. JSS 2 was employed to study the speedup of calculation of the Gaussian process regression.
