Abstract
This invention discloses a pose tracking apparatus operative to track the pose of a moving object based on magnetic flux measurements taken in the vicinity of the moving object. The pose tracking apparatus includes a non-linear Kalman filter-based tracker. The tracker is operated to receive magnetic flux measurements performed in the vicinity of the moving object, and to operate a non-linear Kalman-type filter on said measurements, thereby to generate information regarding the pose of the moving object. In addition, the pose tracking apparatus includes a pose indicator operative to provide an output indication of the information regarding the pose of the moving object.
