AN APPARATUS AND METHOD FOR THE POSITIONING OF A TOOL OF A GROUND ENGAGING VEHICLE

A ground engaging vehicle including a ground engaging tool, an actuator, a global positioning system (GPS) and a control system. The ground engaging to ol extends from the vehicle, and has a reference feature. The actuator is connected to the ground engaging tool, and the actuator is configured to move the ground engaging tool relative to the vehicle. The actuator has a position sensor associated therewith. The GPS is positioned in a substantially fixed position relative to the referenc e feature. The GPS issues three dimensional location information. The control system is configured for receiving positional information from the position sensor and the three dimensional location information. The control system is also configured for processing t he location information and sending a command to a non-GPS constrained algorithm that receives the command and determines a movement of the actuator dependent on a difference between the location information and a desired position of the reference feature. The non-GPS constrained algorithm issues a movement instruction to the actuator dependent upon the difference and the positional information.
