Abstract: A machine navigation system includes a monitoring mechanism for monitoring configuration of an implement movable between configurations relative to a frame such that a center of mass of the machine moves in response to the moving of the implement. A second monitoring mechanism monitors track speed in the machine. A location of an origin of the track speed varies based upon location of the center of mass. A control unit is coupled with the monitoring mechanisms and structured to determine a control term for compensating for movement of a reference location on the machine relative to the track speed origin. The control unit further calculates velocity based on the track speed and the compensatory control term.
