Abstract
The present invention provides operators the ability to follow a predetermined path and achieve desired digging depth by watching steering and elevation indicators of just one system. The indicators are activated by data derived from the interception of signals generated by a single laser transmitter and a receiver array mounted on the machine. The system according to the present invention uses the multiple, tilted fan beams provided by the laser transmitter to calculate elevation angle and azimuth of the tool carried by machine.
