1. A rate sensor for detecting rotation about first and second mutually perpendicular axes, comprising first and second masses coupled together for torsional drive mode oscillation of equal amplitude and opposite phase about third axes which are perpendicular to the first and second axes, the first mass being mounted for oscillation about the second axis in response to Coriolis forces produced by rotation about the first axis, and the second mass being mounted for oscillation about the first axis in response to Coriolis forces produced by rotation about the second axis.
