Leica Geosystem’s GradeStar 3D motor grader control system can be used with either GPAS or TPS sensors to control the blade’s elevation, Aslope and position. The position of the blade is measured by either a mast-mounted GPS antenna or a 360-degree prism for applications where total stations are used. Position data is transmitted via radio to a computer on the motor grader, where the tilt and rotation of the blade are compared with a computer-generated design surface. The computer then calculates the difference between the blade and a digital 3-D terrain map and moves the hydraulics accordingly. The operator can select and switch easily between several TPS or GPS sensors and applications. By using the guidance system you can complete a variety of jobs without staking out hubs or setting up stringlines.
