Abstract: This work presets one of the ways to compensate for the bias in differential mode of Coriolis vibratory gyro operation. To compensate for the bias it is necessary to know both channels scale factors, SFx and SFy of differential Coriolis vibratory gyro, which, as a rule, are known by the results of calibration procedure and elastic wave angle  relative to one of the two drive axes which can be established in advance. This paper presents the different variants of bias compensation algorithms which can be applied to compensate for initial gyro bias and bias drift in motion. Experimental results on differential Coriolis vibratory gyro key parameters temperature influence are also presented.
