There are many GPS devices around such as the EM406a that are cheap and will connect to the Raspberry Pi.

It's one of those things we will be covering over at http://www.worldofpi.com once I get a board to start doing stuff with.

I've got  Bluenext USB GPS device working fine.

Not sure if the question has been approached correctly, the question is really will the operating system support GPS modules. As with most computer hardware issues usually resulting from software issues, or the operating system not correctly being able to recognise the hardware and its functions, not usually a problem with the computer.

Most GPS units will allow you to pull the raw GPS data as a string via the Serial/USB interface. It's relatively striaghtforward to write software to pull this data and there's plenty of them out there. Just google "Linux GPS Tools"

Now, if you want to actually use it to plot position on a map, that takes a bit more work, but once you have the raw position/speed data, it's really just a matter of plotting it somehow.

Most USB GPS modules have a simple USB-Serial interface which is supported by the Pi. Then you just need to install GPS software, a a simple apt-get install gpsd. Hey presto, most USB GPS stuff will just work.

PI runs Linux.

Linux supports GPS.

And it's as simple as that.

Google for GPSD for starters.

Most GPSs these days are USB devices and they're very well supported.
