摘要：

In this paper, a method to improve the long term stability of a virtually rotated rate integrating gyroscope (RIG) is reported. The fluctuation in the virtual rotation rate causes the angle instability. The virtual rotation rate is estimated from the resonant frequency of the gyroscope structure. Using the proposed method, the RIG could operate over than 7 hrs with the bias instability as small as 2.5 degrees=hr and the angle random walk as small as 0.002 degrees=s(0.5).
