    • An apparatus and method determines the position of a point on a work implement attached to and movable relative to a mobile machine. The apparatus includes a site coordinate system position sensor mounted on the mobile machine, a ground speed sensor mounted on the mobile machine, an implement position sensor mounted on the mobile machine and coupled to the work implement, and a pitch sensor mounted on the machine. A controller is adapted to receive a reference point position signal from the site coordinate system position sensor, the reference point position signal being indicative of a position of a reference point on the mobile machine in a site coordinate system, to receive an implement position signal from the implement position sensor, a ground speed signal from the ground speed sensor and a pitch signal from the pitch sensor, and to determine the position of the point on the work implement in site coordinates compensating for the pitch of the machine and the translational movement of the machine as a function of the reference point position signal, the implement position signal, the ground speed signal, and the pitch signal.
