As technology continues to enhance our world, Caterpillar is constantly developing and refining advanced technologies to help make your equipment more productive and efficient, and to help you more effectively manage equipment fleets and operations.
From advanced engine technologies to in-cab monitoring – from machine health management to fleet-wide information systems – Cat technologies are reshaping the process of using, managing and owning heavy equipment.
AccuGrade UTS is a high accuracy dynamic tracking system that uses an Universal Total Station (UTS) to track a machine and monitor blade positioning.
An UTS instrument on the work site is used to track a target, which is mounted on the blade of the machine, to determine precise 3D positioning.
Active target technology allows the system to reliably lock onto and track the intended target. This ensures the correct machine is being tracked and eliminates false lock-ons to other active machine targets, survey crews, or reflective surfaces. Built-in search intelligence allows the system to quickly search for and find the target when the lock is lost due to a passing vehicle or other interruption.
The UTS instrument continuously measures the target’s position and transmits real-time positioning data to the operator via the in-cab display, which shows the exact position of the blade in relation to the design. The system combines the position of the target with the known position of the instrument, machine measurements and sensor outputs to calculate precise positioning of the blade tips. The system uses the positioning data to calculate desired elevation and cross slope. Cut and fill values are computed by comparing the position of the blade with the design file. The system makes automatic blade adjustments typically performed by the operator and provides automatic blade control to one or both cutting edge tips.
AccuGrade UTS puts the information the operator needs to complete the job in the cab. The operator simply steers the machine to achieve fine grade surfaces with high-precision accuracy.

Current earthmoving and fine grading processes are labor intensive and dependent on manpower and instruments. Maintaining consistent grade between stakes is challenging, even for experienced operators. AccuGrade GPS reduces labor requirements and helps operators work to the design plan by accurately cutting, filling, and reducing material cost.
The AccuGrade GPS control system is the best solution when the construction site involves contours, rather than single or dual slope planes. The AccuGrade 3D system uses GPS technology to compare the blade position to a three-dimensional computerised site plan and signals the operator or hydraulic system to raise or lower the blade to achieve the design requirements.
The AccuGrade GPS Grade Control System is a high technology machine control and guidance system that allows dozer operators to grade with increased accuracy, without the need for survey stakes. Digital design data, in-cab operator guidance features and automatic blade controls help the operator achieve grade faster, meaning higher productivity, lower operating costs, and greater profitability.
AccuGrade GPS is designed for a wide range of construction earthwork applications, from bulk clearing with high production rates to finish grading with tight tolerances. Flat, single and dual sloping planar designs, such as building pads, parking lots, roads and highways, can be created on-board the machine using the AccuGrade GPS system. Complex 3D designs, such as golf courses and roads with super elevations, can be created in the office by design engineers and loaded onto the system via a compact flash card.
