In evaluating a satellite mission which requires a pointing stability in a short term such as camera exposure, the microvibrations generated from satellite internal disturbance sources such as reaction wheel or stepping motor become critical factors which degrade the pointing stability. Taking SELENE satellite as an example, this paper shows a microvibration management synthesis consisting of microvibration management and pointing stability analysis. This method is capable of specifying the microvibration requirements for each disturbance source, and evaluating the total influences of all the internal disturbance sources on pointing stability in consideration of the satellite flexible structural characteristics. Several tests that concern SELENE's microvibration management are introduced, either.
