The Leica MC1 Excavator 3D is a GNSS and sensor-fusion system for excavators that tracks bucket tip position in 3D space, achieving 30–50mm bucket accuracy for trenching, grading, and foundation work.
Leica MC1 Excavator 3D — Complete Specs, Manual & Guide
Category: Machine Control | Brand: Leica | Model: MC1 Excavator
The Leica MC1 Excavator 3D system extends Leica's iCON machine control platform to excavators. Using a combination of GNSS positioning and iCON grade sensors on the boom, stick, and bucket, the system continuously calculates bucket tip position and compares it against a loaded design surface. Operators see real-time depth and slope guidance on the MC1 cab display without manual grade checking.

Frequently Asked Questions — Leica MC1 Excavator
How accurate is the Leica MC1 Excavator 3D system?
The MC1 Excavator achieves 30–50mm bucket tip accuracy under normal GNSS conditions. This is sufficient for trenching to grade, rough grading, and foundation excavation. Final trim grading below 30mm requires additional field checks.
How does the excavator system track bucket position?
The system uses three iCON grade sensors on the boom, stick, and bucket linkage to measure joint angles. Combined with the machine's GNSS position and heading from the dual antenna system, the software computes the 3D position of the bucket tip in real time.
Does the MC1 Excavator need a base station?
Yes. An RTK base station or NTRIP network connection is required to achieve the positioning accuracy needed for grade control. Without RTK, the system falls to autonomous GNSS accuracy of 1–3m, which is not suitable for machine control work.
What excavator brands does the Leica MC1 support?
The Leica MC1 Excavator system is compatible with Cat, Komatsu, Hitachi, Liebherr, and Volvo excavators. Machine-specific installation kits and boom geometry files are required for each machine type.
