Abstract
An inertially referenced motion sensor that may be rigidly coupled to a relative motion sensor. Signals from the relative motion sensor and inertially referenced motion sensor may be combined to produce an inertially referenced relative signal.
Claims38
An apparatus, comprising:
- a relative motion sensor configured to sense a motion relationship between itself and an object;
- an inertially referenced motion sensor rigidly coupled to the relative motion sensor and configured to sense a motion relationship between itself and an inertial reference frame;
- and
- a combiner configured to combine output signals from the relative and inertially referenced motion sensors to produce a signal representative of a motion relationship between the object and an inertial reference frame.
