I have uploaded a shared object package, which is an interface to GPS receivers. it allows you to determine your current position, heading and speed from a GPS receiver linked to your pc. It also optionally plays various sound files for events such as acquisition of signal, obtaining a fix, losing a fix, loss of signal, changing quality of fix, etc. More than one script can interface with the GPS concurrently.
This does require an NMEA COM driver for your GPS, which runs on the pc. I have had problems with the USB drivers from Delorme, and so do not recommend their drivers. Chip
