Claim:
1. A system for rotationally biasing a fiber optic gyroscope, the system comprising: a fiber optic gyroscope assembly comprising: a motor operatively coupled to the fiber optic coil and configured to apply a periodic rotation to the fiber optic coil to impart a biasing phase modulation to the optical signal; a platform operatively coupled to the motor, wherein at least a portion of the fiber optic gyroscope assembly that includes the fiber optic coil is mounted on the platform; an angle sensor mounted on the platform; and a signal processing unit operatively coupled to the fiber optic gyroscope assembly and the motor, the signal processing unit comprising an angle amplifier configured to receive a dither angle signal from the angle sensor, the signal processing unit configured to convert a measured intensity of the optical signal to rotation rate data.
