I bought an Aldi/Crane GPS clock some time ago. The clock was delivered with a software that runs only on older versions of Windows (up to Vista), but not on Linux.
The clock is already doing its job, logging my tracks with GPS connection. Thus I didn’t want to put it to the trash can, but instead use it further. I searched the internet and found a free software project that created a software to get a connection with the clock and read its data via usb cable. This project is hosted at:
https://github.com/mru00/crane_gps_watch
I checked out the source code and followed the instructions, that includes the usual steps: ./configure, make, make install.
I could connect the GPS clock with my Linux-PC and read the data from the clock inside a shell via:
crane_gps_watch_client
or
/usr/local/bin/crane_gps_watch_client
I used the options ‚–split‘ to create seperate files for every track and ‚–clear‘ to delete the data on the clock.
The file export format is ‚*.tcx‘.
