Heres another problem I might not be able to work out...
Pfft, any problem is solvable, given enough time and SLUGgers *nod*
To do this I need to convert the DB 9 pin to a USB input, I need to read the USB port at 4800 Baud for it to be readable, and to top it all off, I need to be able to write this data to a file - say every 10 minutes, simple text would do.
To plug the GPS in to your laptop, you need an RS232-USB converter. Some of them work, and some of them don't, so it's worthwhile doing a little bit of research before you buy. Get the model number and plug it in to Google or the linux-usb Working Devices list (http://www.qbik.ch/usb/devices/).
FWIW, the Aten adaptor I bought from Everything Linux is great.
You can do everything with these beasties that you can do with a regular serial port. Mine regularly gets used to talk to router consoles at 9600bps.
As for the logging side, you should probably start by searching freshmeat. The first hit in a search for "NMEA" is a package called gpsutil (http://www.cs.uakron.edu/~hennings/gpsutil/), which looks to me to be right up your alley.
Let us know how you go - my inner geek is yearning for a GPS receiver. :-)
