GpsDump is a program for communication between a PC and a GPS Unit. GpsDump can up/download tracklogs, waypoints, CTR data, ++ to most popular GPS devices in the free flying community.

GpsDump can read/write most popular formats of tracklog and waypoint files, it's very small and efficient. USB downloads are handled very quickly, and USB to serial adapters are supported and well tested.

GpsDump is developed by Stein Sørensen, separately from FS, but FS rely on GpsDump for up/download functions.

Using GpsDump

What you will need

  • Latest version of GpsDump downloadable from Stein's homepage
  • A GPS device
  • The corresponding GPS cable
  • You will need the Garmin USB drivers for communication with a Garmin GPS via USB. These drivers are not included with GpsDump.

Downloading a tracklog

  1. Turn on GPS. If Garmin serial, set to GRM/GRM mode
  2. Select Tracklog - relevant GPS in GpsDump
  3. Select points, And so on
  4. Screenshots

Notes on various instruments


  • One should initiate the download in GpsDump (ie press the "XC-Trainer (MXP)" button or use the Logs/... menu) before pressing "SEL" in XC-Trainer. GpsDump will wait "forever" for XC-Trainer to start sending data so no need to rush.
  • Do not use TNC to send the log. This will give you whatever local time the instrument is set to. MXP will give UTC time which is what you want.
  • In some cases you might get some error from GpsDump while trying to download a tracklog. In these cases first try again, then try MXP 1s 19K, then MXP 3s 19K ... If MXP simply will not work for this instrument on this PC & COM port, try it on a different PC or COM port if you have one. Or try the TNC 1s 57K or 9.6 (set local time to same as UTC time first).

Uploading waypoints

  1. Turn on
