A symmetrical micromechanical gyroscope includes an inertial mass symmetrically supported about both drive and sense axes, for detecting rotational movement about an input axis. Two pairs of flexures attached to diametrically opposed sides of the inertial mass support the mass within a gyroscope support frame. Each of the flexures are oriented at generally a 45 DEG angle from both the drive and the sense axes. In response to an applied drive signal, the inertial mass is induced to vibrate about a drive axis which is co-planar with and orthogonal to the sense axis. Both pair of flexures participate equally during rotation of the mass.
