CHCNav TD63 Pro 3D Automatic Control System for Dozers

The CHCNav TD63 Pro is a fully automatic 3D control system designed to enhance the precision, productivity, and consistency of earthmoving and fine-grading operations. Combining dual GNSS antennas with a 100 Hz IMU sensor, it achieves ±2 cm accuracy and precise blade control—regardless of machine position or operator experience. The result is a perfectly finished grade with minimal staking, reduced rework, and faster project completion. Powered by CHCNav’s DO-Tech algorithm, the TD63 Pro intelligently controls hydraulic flow to maintain grade accuracy at varying speeds and on any terrain. Designed with the operator in mind, the MCNAV control tablet features a clear, responsive interface that shortens the learning curve. Installation and calibration are straightforward—complete setup can be done in under six hours, with 30-minute calibration. The TD63 Pro supports a wide range of coordinate systems, radio protocols, and design file formats.
