The MCNAV TX73 is a 3D excavator machine control system that combines advanced GNSS receivers with robust IMU sensors to accurately determine the bucket tip’s position. Real-time excavator grade control against the design surface lets the operator dig straight to target depth, significantly reducing the need for traditional survey methods. As a result, the TX73 boosts productivity and cost efficiency, enabling projects to be completed faster and more economically.

The TX73's high-precision GNSS positioning uses full GNSS constellations and advanced IMU sensors to deliver real-time excavator grade control, reducing human error and over-excavation while maintaining the alignment, depth, and slope essential for high-quality results.
Safety is improved by making as-built drawings visible to machine operators, who can anticipate potential hazards such as underground utilities. Automated guidance minimizes worker exposure to hazardous environments and reduces the likelihood of accidents.
