They work anywhere that the signal reaches.  That means Germany and 
perhaps any place within 200-300 KM of the transmitter.

Unless you are very lucky, you won't get one that meets your 
specifications!  If you drop the requirement for a PCI card and are 
willing to do a little soldering, you can have a GPS refclock for less 
than $100 US!   Take a look at the Garmin GPS18LVC.  You have to solder 
an RS-232 connector and provide 5VDC somehow but the price is right!

If you DO find a GPS on a PCI card for less than 200 Euros, please let 
us know; most of us will probably want one!
