MESUREMENT OF THE SOLAR ARRAY PANEL'S VIBRATION CAUSED BY THERMAL SNAP AND DELTA-V USING MONITOR CAMERAS ON THE GREENHOUSE GASES OBSERVING SATELLITE (GOSAT)

摘要

When a low Earth orbiting satellite goes through the eclipse, rapid cool down or rapid warm up of the solar array panels occur. These cause vibrations of the solar array panels and disturb satellite attitude stability. Since vibration of the solar array panels is very slow and therefore it is difficult to measure the vibration by such as an accelerometers. This paper reports vibration measurements result that were gained using satellite mounted CMOS camera's images. This paper introduces measurement system and measurement ways. Then, image processing to measure the vibration is conducted, and results of the measurement and vibration analysis are introduced.
