Three elements of machine control are important in grading jobs. There are laser-based display systems, which can be mounted on top of a machine, with some providing 360-degree operation. The receiver is a stand-alone item. There are also laser-based grade-control systems. The signals from the receiver can be used to automatically correct the blade, with systems that can be customized to the needs and dimensions of each job. They can reduce stake-out requirements and increase the job cycle. Finally, there is 3-D grade control, which uses X, Y and Z coordinate measurements that compare the machine blade location with the data from a pre-loaded digital terrain model. Elevation and cross-slope designs can then be calculated with automated blade adjustments. Additional, there is an optional advanced track sensor robotic station, for precise finished-grade work. Laser augmentation can provide another way for more precise grading in tight tolerance situations.
