ABSTRACT:
An apparatus and method for determining the position of a work implement movably connected to a machine utilizes first and second electromagnetic radiation receiving devices connected to the work implement at predetermined spaced locations. A processor determines the first and second current coordinate positions of the first and second receiving devices in a site coordinate system based on position signals from the first and second receiving devices. The processor transforms the first and second points from a local coordinate system related to the machine to the site coordinate system using a plane passing through the first and second current coordinate positions and a mid-point located along a substantially straight line passing between first and second previously defined coordinate positions of the first and second receiving devices. The processor corrects the position of the first and second points in the site coordinate system based on sensed changes in the pitch of the implement.
