Abstract :
Fiber Optical Gyroscopes (FOGs) have been used as satellite attitude sensor because of low power and small body. To keep FOG bias rate stable, temperature control is needed. However it is reported that thermal input of temperature control causes Shupe effect. Due to Shupe effect, bias stability of FOG is deteriorated. In this paper, Shupe effect compensation method of FOG with temperature control is proposed. Experimental results show proposed method is efficient to compensate Shupe effect. And as a result of Shupe effect compensation, FOG performance of all time range is improved.
