A single-axis rate sensor for determining angular speed theta in inertial space of an object rotating about the axis. The rate sensor includes a mass, a motor for rotating the mass about the axis at an angular speed omega relative to the object, and a microcomputer for determining a centrifugal force at a radius R from the axis due to the rotation of the mass about the axis at an angular speed OMEGA in inertial space, where OMEGA is the sum of theta and omega . Alternative embodiments provide a closed loop system where OMEGA is held constant, and a dual rotor arrangement which can be used to reduce a nonlinear factor in a relationship between theta and centrifugal force and/or to provide an in-operation self-checking feature.
