gpsdX

location based services

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!
