The paper proposes a rather simple rotating device based on the Maltese cross for the precision test turntable of the calibration of gyroscopic sensor elements of inertial class. The device is complemented by a mechanism of stiff and unambiguous caging in fixed positions. The problem of combining these two functions of rotation and locking is solved without increasing the number of elements of the mechanism and its complexity. This paper presents the kinematic analysis of the proposed device and optimization of its parameters, taking into account manufacturing tolerances. To reduce the magnitude of friction in the caging device, we provide a special mechanism to ensure a decrease in pressure between the contacting surfaces.
