1. An inertial unit comprising an inertial core that is connected to a control unit and that includes three gyros that are mounted relative to one another so as to have sensing axes that are substantially perpendicular to one another, the gyros being vibrating axisymmetric gyros with hemispherical resonators, wherein the inertial core is mounted on a carousel arranged to drive the inertial core in rotation about an axis of rotation at at least one predetermined frequency of rotation and wherein the axis of rotation coincides with a trisector of the sensing axes.
