I use gpsd + netcat to log nmea and then convert that to gpx using
gpsbabel. I have a runlevel that starts gpsd + netcat, and when I go
back to my ordinary runlevel I have a task startup service that
handles the conversion.

basically:
date=$(date +%s);netcat localhost 2947 > $date.nmea
gpsbabel -i nmea -o gpx -f $date.nmea -F

None defined in gpx, and gpsbabel doesn't save that information when
it converts to gpx that's why I archive the nmea logs.
