1. A device comprising:

  • at least one sensor configured to sense rotation of said device about a first axis and to generate at least one first output associated therewith; and

    a zero-rate output (ZRO) tracking filter configured to receive said at least one first output and to compensate said at least one first output for a bias associated with said at least one sensor, wherein said ZRO filter is implemented as a Kalman filter having at least one constraint enforced on at least one parameter associated therewith.
