TUnIS Navigation MTGyro
Gyro-based all-rounder system for long-distance and curved drives.
A north-seeking gyro-compass installed inside the TBM enables precise calculation of the machine position.
The vertical TBM position can be calculated either in the classic way using the hydro level system or alternatively using the newly integrated vertical coupled navigation.
The fact that this system variant does not require any line of sight in the pipeline makes it particularly suitable for use in small diameters and for alignments with tight radii curves.
