Abstract: An augmented reality system for viewing a static physical object includes a movable unit receiving signals from, a static tracking base station for obtaining the six-dimensional absolute position of the movable unit. The relative position of the movable unit relatively to the static physical object is calculated from the absolute positions of the movable unit and the static physical object. The relative unit-object position is then used for rendering and displaying an augmented image or projecting a virtual object on the static physical object.
