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.
- High-Accuracy Dual GNSS Positioning Equipped with dual GNSS receivers, the TD63 Pro delivers centimeter-level accuracy, ensuring precise 3D positioning and heading even when the machine changes direction or operates on steep grades.
- 100 Hz IMU Sensor for Real-Time Stability The integrated IMU sensor provides a 100 Hz update rate, delivering fast, stable positioning feedback for consistent blade control across uneven terrain.
- Automatic Blade Control Real-time hydraulic control automatically adjusts the blade to follow the design surface, maintaining finished-grade accuracy and reducing the need for manual input or staking.
- Intelligent DO-Tech Algorithm CHCNav’s DO-Tech algorithm optimizes hydraulic response for smooth, stable blade motion at varying speeds, improving efficiency and grading consistency on every pass.
- User-Friendly Interface A 10.1″ sunlight-readable Android tablet running MCNAV software provides a simple, intuitive control environment. The clear layout and guided calibration help operators get up and running quickly.
- Broad Compatibility The system supports all dozers equipped with pilot or PVG hydraulic valves and integrates easily with existing machine systems. It also supports TT450S, Transparent, and Satel_3AS radio protocols.
- Multi-Format Design Support Compatible with industry-standard design file formats including .crd, .dc, .cal, .lok, .jxl, .loc, .rodx, .dxf, and .landxml, ensuring seamless data sharing across projects.
