OpenGPS
Open Source GPS Receiver
OpenGPS is an implementation of Cliff Kelley's OpenSourceGPS adapted for a PCI bus interface. See his excellent web site for more information on OpenSourceGPS. GPS receiver hardware is available from GPS Creations. OpenGPS runs on the real time operating system RTAI-Linux. It compiles with gcc using a RTAI-patched linux kernel. See www.rtai.org for details on how to install and run RTAI.
