In conventional tunnel construction, workers have to operate directly at the tunnel face, which puts them at risk. In addition, the machine operator often does not receive continuous information about the current excavation progress. This can lead to rework, higher shotcrete consumption and increased costs. TUnIS Navigation Excavator addresses these challenges through automated position tracking and real-time visual feedback, allowing precise profiling and safer working conditions for everyone underground.

TUnIS Navigation Excavator combines total station, prism tracking and gyroscope technology to continuously determine and update the excavator position inside the tunnel. The data is transmitted via radio to the TUnIS computer. The system can be easily adapted to different excavators and extended with TUnIS Office for data analysis, configuration and monitoring from the construction office.
