An electronic unit typically inside a container located on the ground surface that controls the operation of the microtunneling machine. As the machine operator drives the tunnel from the control console, electronic information is transmitted to the control console from the MTBM. This information includes head position, steering angle, jacking force, penetration rates, machine-face torque, slurry charge and discharge flow rates and pressures, and laser position. Some control consoles are equipped with a computer that tracks and stores the data and allows real‑time analysis of the tunnel drive.
