TUnIS Navigation vs VeloGPS

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. With this version the following navigation tasks are supported: • Display of TBM position • Start & stop navigation • Orientation • Direction check • Relocate total station to a new bracket • Joystick for an easier aiming of the total station to a prism • New prism measurement • Segment reference prism measurement (version 3.5 or higher) • Free stationing • New backsight prism (moving station system) • Position determination (moving station system) • RCMS sections configuration The app is compatible with Tunis Version 3.19 or higher, and runs on smartphones and tablets.

VeloGPS turns your iPhone into a full handheld GPS. Precise coordinates, barometric altitude, compass, waypoints, track recording, and GPX export — everything a dedicated GPS unit does, on the device you already carry. Built for hiking, cycling, kayaking, sailing, skiing, backcountry travel, geocaching, and anything else you'd reach for a handheld for. Live GPS Dashboard A frost-glass overlay on the map shows coordinates, speed, and direction by default — tap the chevron to expand for altitude and pressure. The Info tab gives you the full readout: coordinates, speed, altitude, course, compass heading, and barometric pressure on one screen. Coordinates display in DD, DMS, or UTM. Track Recording & GPX Export Record your route with a single tap. Tracks auto-pause when you stop and resume the moment you move again, so distance and elevation gain reflect what you actually did. Each track is auto-classified as cycling, hiking, running, walking, driving, or flying based on motion sensors during recording. Saved tracks appear as colored polylines on the map and export as standard GPX files — complete with metadata block and activity type — for any mapping tool. Rename, recolor, re-tag activity, toggle visibility, swipe to delete with undo. Smooth, Accurate Altitude A fused altimeter combines the iPhone's barometer with GPS for steady, responsive elevation — with an outlier filter that rejects physically impossible pressure spikes from tunnels, doors, and cabin-pressure changes. EMA smoothing keeps recorded altitude clean. On iPads and devices without a barometer, GPS-only smoothing keeps the reading stable. Waypoints Save your current location with one tap. Tap a pin on the map to jump to details. Distance to each waypoint updates as you move. Mark trailheads, campsites, caches, hazards, summits — anywhere you want to find again. Interactive Map Standard, Hybrid, and Satellite views. A live accuracy circle shows your GPS precision. Tracking mode centers the map on you; pan or pinch to release it instantly. Long recorded tracks render smoothly at every zoom level. Haptic feedback confirms every interaction. Flight Mode A dedicated mode for aviation: GPS altitude (cabin pressure would corrupt the barometric altimeter), pre-flight checklist, and tuned filters. Live Activity & Lock Screen Keep speed, coordinates, altitude, distance, and your activity glyph on your Lock Screen and Dynamic Island — even when the app is in the background. Charts & Session Stats Real-time charts for speed, altitude, and pressure with windows from 1 minute to 1 hour. Session stats show distance, elevation gain/loss, max speed, average moving speed, and current grade — now on a true rolling window so the last hour is always the last hour. Power Saver Extend battery on long outings. Lowers GPS update frequency, pauses the magnetometer, and auto-suspends GPS when you're stationary. GPS Signal Quality A color-coded toolbar indicator shows your fix quality at a glance. Tap for detailed horizontal, vertical, speed, and course accuracy — plus a Processing section showing the current altitude source (fused, GPS-only, or flight mode) and live motion activity. Flexible Units Coordinates in DD, DMS, or UTM. Speed in mph, km/h, or knots. Distance in imperial or metric. Pressure in kPa, hPa/mbar, inHg, or mmHg. iPhone & iPad Tabbed navigation on iPhone, sidebar on iPad. Adapts to split-screen and slide-over. Portrait and landscape.
