Abstract
A rotation sensor system is presented. The system comprises a rotating frame configured to be mounted on a gimbal and adapted for controllable rocking motion about a predetermined axis of said frame, and a proof mass assembly mounted on said rotating frame. The proof mass assembly comprises one or more proof mass elements each mounted for controllable movement with respect to the predetermined axis along a certain path, a distance of each proof mass element from said axis corresponding to a direction of the rocking motion of said frame, thereby affecting a moment of inertia of said rotating frame.
