TUnIS Navigation

VMT GmbH

About this app

VMT stands for the best-selling Navigation systems in tunneling worldwide. We have equipped thousands of tunneling projects with navigation, information, monitoring and communication systems since 1994. We make sure to guide tunnel boring machines to their destinations with millimeter accuracy. For easier handling of the navigation tasks we offer in addition to the navigation system on the PC in the control cabin the Tunis Navigation Mobile App.

You are more flexible with the app and you can use TUnIS even outside from the control cabin. If the app is in use, then the navigation software at the control cabin is blocked. But you can see at PC what the person with the app is doing and the person at the control cabin has always the possibility to close the connection to the app.

This app can be used only by obtaining a connection to our PC navigation software. To purchase the PC software, please visit our website www.vmt.global.
