This paper presented a silicon micromachined gyroscope for the autopilot of the spinning projectile.The characteristics of the gyroscope is that gyroscope replaces a drive force from the drive conformation with a rotating force from the spinning projectile and that the output signal contains the information of the self-rolling,yawing and pitching angular rate of the spinning projectile.According to the conformation and working principle of the gyroscope,the motion equation is established.For gyroscope signal characteristics,the algorithm which can simultaneity extract the self-rolling,yawing and pitching angular rate of the spinning projectile from a output signal and the algorithm which can eliminate the change of the gyroscope scale factor resulted from the change of the self-rolling angular rate of the spinning projectile are presented.Both the principle and the algorithm are validated by the experiments.
