For on-line vehicle tracking I wrote a little daemon to run on my
OpenMoko FreeRunner phone; it gets position from gpsd and forward
it to a remote database server using UDP packets over GPRS
It works very well, it seems also that GPRS modem does some
buffering when switching from cell to cell, because I exprience
very few data loss also away from cities. I send a position every
10 seconds, I lost max 3% of packets here in Italy.
The UDP connection is "send and forget", no retry is made. An
improvement of the software can be some sort of acknowlegment and
Here you can find that experiment:
Firenze - Italy
