This work presents investigation of differential Coriolis vibratory gyroscope ability to externalshock suppression. First of all pulse amplitude in voltage caused by external mechanical shock of 100 g isestimated for the two sensor designs. Then, using differential Coriolis vibratory gyroscope Simulink model,output signals of two measurement channels are analyzed. It is shown that differential Coriolis vibratorygyroscope damps amplitude of erroneous angle rate caused by shock directed along sensing axis of no lessthan 3 times in comparison with non differential Coriolis vibratory gyroscope. Influence of lateral shock isalso analyzed
