Abstract
A rotation sensing system includes a rotation sensor that produces a signal in response to an input rotation about a sensing axis. A servo system is arranged to rotate the rotation sensor at an angle about the sensing axis to null the signal from the rotation sensor such that the rotation sensor is substantially inertially stable. The rotation sensing system is mounted on a resolver arranged to measure the angle through which the servo system has rotated the rotation sensor.
