QAmbit

QAmbit puts Suunto Ambit watches in QGIS. It does what openambit2 does, and uses QGIS's own tools wherever QGIS has one: layers, styling, 3D views, the elevation profile, the time slider, Processing and the task manager.

openambit2	QAmbit
Device detection (udev)	Watches /dev for Suunto HID devices (vendor 0x1493)
Sync: moves, time, GPS orbit	openambit-cli run as a QGIS task, with progress and cancel
Log list and log view	Panel listing the moves; tracks, fixes and laps as GeoPackage layers
Leaflet 2D map	QGIS map canvas, basemaps from the HCMGIS plugin
CesiumJS 3D map	QGIS 3D view, opened automatically for air sports
Terrain (Terrain Tiles / Copernicus)	Terrain Tiles layer, Copernicus DEM, IGN LiDAR HD (50 cm, France)
Altitude chart	QGIS elevation profile along the selected move
Replay	QGIS temporal controller on the fixes
Sport mode editor, air sports templates	Sport mode dialog, same sport_modes.json
Training plans	Training plan dialog, same training_plans.json
Settings dialog	QGIS Options ▸ QAmbit page

Movescount upload and the Movescount App Zone compiler are not carried over: the service is gone.

Requirements

• QGIS 3.34 or later (Qt5 or Qt6), with 3D support for the 3D views.
• openambit-cli from openambit2 with the offline options (--info-json, --orbit-file, --sport-modes, --training-plan). QAmbit looks for it in ~/dev/openambit2/build/src/openambit-cli/, on the PATH, then in /usr/bin and /usr/local/bin; another path can be set in the options.
• Read/write access to the watch's hidraw node (the udev rule shipped with openambit2).
• The HCMGIS plugin for basemaps (declared in plugin_dependencies). Everything else works without it.
• For GPS orbit updates: openambit2's tools/rinex2ubx_ambit.py.

Install

From a clone:

make deploy          # links this folder into the default QGIS profile

then enable QAmbit in Plugins ▸ Manage and Install Plugins. make zip builds a package for Install from ZIP.

Use

• Sync: plug in the watch and press Sync. QAmbit updates the GPS orbit file, reads the new moves into ~/.openambit, sets the watch time, writes the orbit, then imports the moves into the store (~/.openambit/qambit.gpkg). New air sports moves open in a 3D view.

• Moves: selecting moves in the panel zooms to them; Show only the selected moves filters the layers. Tracks are LineStringZM (Z altitude, M seconds from the start), styled by category (air, ground, water, vertical, underwater). The Track points layer is time-enabled: the temporal controller replays a move.

• 3D view: drapes the HCMGIS 3D basemap over the terrain and shows the tracks at their recorded altitude. A geographic or Web Mercator project is switched to the local UTM zone, so distances and heights are true; the project's full extent is set to the moves, the extent QGIS builds the scene over.

  

• Detailed terrain: downloads the elevation around the selected moves and makes it the project terrain (3D views and elevation profile):

  • IGN LiDAR HD in metropolitan France: the surface model (MNS, with trees and buildings, the default) or the terrain model (MNT). The Geoplateforme WFS gives the coverage and the WMS-R serves any Lambert-93 box at any size, so QAmbit fetches the box itself at the finest resolution that keeps it under 64 Mpx (0.5 m for about 4 x 4 km, 5 m for 25 x 25 km), in 2000-px chunks. Same services as the r.in.lidarhd GRASS addon.
  • the Copernicus DEM elsewhere (GLO-30 up to about a degree, GLO-90 above). Results are cached in ~/.cache/qambit/dem.

• Elevation profile: opens a QGIS elevation profile along the first selected move.

• Sport modes and Training plans: edit the openambit2 files and write them to the watch. Air sports templates use the Altitude mode, so that climbs are not taken for weather changes.

• Processing: QAmbit ▸ Suunto Ambit has Import openambit logs and Download terrain (IGN LiDAR HD / Copernicus DEM), for models and batch runs.

Long jobs (sync, import, terrain, orbit) also report to MetaMonitor when its spool is present.

Translations

French is included. make ts refreshes i18n/*.ts from the code and make qm compiles them; QAmbit follows the QGIS user interface language.

Tests

make test                         # pytest, headless QGIS
QAMBIT_NETWORK=1 make test        # also downloads a small LiDAR HD tile

The fixture tests/data/log_TEST000000000001_2026_07_01_10_00_00.log is a synthetic flight, not a real recording.
