Welcome to Robin's GPS utilities for Mac OS X. This page includes a couple of utilities for using GPS with other free or open source programs for OS X... and although none of the programs here are truly "stand-alone", I think you'll enjoy playing with them.
Many thanks to the folks on the KisMAC mailing list who have helped me test these utilities. If you enjoy them, or have any feedback to offer, or if you have any problems with them, please let me know!
GPSd is an open-source GPS daemon, which allows you to share data from a single GPS source with multiple applications on one or even many computers. Not only can it reproduce raw GPS data to an (effectively) unlimited number of clients, but it can also provide fully parsed, on-demand GPS information to any client program.
gpsdX is a Mac OS X native, Universal Binary build of GPSd. It comes complete with an installer, and a GUI configuration utility to set it up to launch when you start your system. gpsdX is all you need to get started using GPSd on your Mac!

GPS-to-Google Earth, or gps2ge, is a utility to monitor your GPS position and track in Google Earth.
