S192013 超小型衛星における振動型MEMSジャイロセンサの軌道上校正方法について([S192-01]宇宙システムに関する実践的解決と知見の汎用化(1))
詳細
In this paper, an on-orbit calibration method for vibrating structure MEMS-gyroscopes for micro-satellites is proposed. The purpose is high-accuracy attitude determination with low power consumption sensors under tight restriction of electrical power. This research is based on a micro-satellite " TSUBAME " , which is being developed at Matunagalab, Titech/ISAS. If MEMS-gyroscopes are calibrated by fiber optic gyroscopes once, then the subsequent attitude of the satellite is determined accurately with low power consumption sensors during the normal operation. The effectiveness of this method is confirmed by the numerical simulation.
