Abstract

Readout signals of a dithered ring laser inertial integrating rate sensor are processed by a signal combining circuit which forms part of a closed loop scheme for removing the dither signal other than the base motion component thereof. The output of the signal combining circuit has a computed base motion component removed therefrom by a second signal combining circuit. The output of the second signal combining circuit is used to control a correction signal that is subtracted from the gyro output signal by the first signal combining means. The correction signal is multiplied by a ratio of the rotational inertia of the sensor over the sum of the rotational inertia of the sensor and the rotational inertia of the base to obtain the computed base motion component of the dither signal.
