GPSDump
A free utility for hang-gliding and paragliding pilots to exchange tracklogs, waypoints, routes and airspace data with GPS flight instruments, and to upload flights to online contest and logbook servers. Non-profit, and driven by the flying community that uses it.
What it does
- Read the instrument's flight list so you can select what to do with them
- Download tracklogs from your flight instrument and save to file or upload to an online service. Supports many file formats.
- Upload flights directly to XContest, Flightlog and XCGlobe, to your own FTP or HTTP server, and validate IGC files online.
- Send a whole batch at once. Tick six flights and all six go, to any destination.
- Keep a list of your wings and pick one, instead of typing "Moyes RX4" into a different box for every server you file to.
- Exchange waypoints and routes with your instrument in the common formats (SeeYou, CompeGPS, OziExplorer, WinPilot, GPX, KML, XCTrack tasks, …).
- Upload airspace (CTR) data to instruments that support it, with filtering by area and class.
Supported instruments
Flymaster (incl. NAV C), Brauniger/Flytec (Compeo, Competino, 5020 and the IQ series),
Flytec Element, Digifly AIR, Leonardo Pro BT (Bluetooth), Syride, Ascent, Naviter
Oudie/Blade and SkyDrop — over USB cable, Bluetooth, USB-HID or as a mounted drive,
depending on the instrument. Instruments that simply expose a card of .igc
files can also be read as a plain USB drive, even if the model is not known to GPSDump.
Older instruments that version 3.0 no longer supports — Garmin handhelds over the Garmin protocol, MLR, Aircotec XC-Trainer, MTK/Pentagram loggers, and the Leonardo by cable — are still handled by the original Windows GPSDump on gpsdump.no.
Platforms
Android — on Google Play (Android 6 and newer). Connect instruments over USB OTG or Bluetooth.
Desktop — a new GPSDump for Windows and Linux, built on the same core as the app, is in development. Until it arrives, the original Windows GPSDump is still available from gpsdump.no.
The story of GPSDump
It started around 1998 with a Garmin 12, a Norwegian online logbook, and the problem that
the tracklog was stuck inside the GPS. Stein Sørensen wrote GpsDump in C for Windows to get
it out — and then kept going for nearly thirty years, adding instrument after instrument as
pilots asked for them, and porting it to Windows Mobile, Mac, Linux, FreeBSD, Kobo
e-readers and, in 2012, Android. In 2026 the code changed hands, and GPSDump is being
rebuilt on a shared modern core — free, non-profit and community-driven as it has always
been.
Latest release
Version 3.0 for Android, October 2026 — a simplified interface that remembers your
instrument, light and dark mode, and your latest flight sent online to Flightlog, XContest
or the new XCGlobe in a few clicks. Tasks, XCTrack tasks and openAIP airspace go straight to
your instrument, files land in Documents/GpsDump/, and the app is now fully
translated to Italian and Slovenian. See the changelog.
