Abstract
To measure, in a reference frame, angular displacements of a privileged axis tied to a carrier, angular velocities or angular increments of the carrier are measured about two axes tied to the carrier, which axes are orthogonal to each other and at an angle of about 90.degree. the privileged axis. Said mutually orthogonal axes are caused to rotate at high speed about said privileged axis. The angular positions of said mutually orthogonal axes about the privileged axis are determined continuously relate to a reference position. Their angular displacements are calculated by integrating their angular velocities while taking account of said angular positions of the orthogonal axes about the privileged axis.
