fastgps GPS software receiver
fastgps is a GPS software receiver written in c++, which aims to be fast. Like all software receivers, fastgps performs all signal processing in software, which allows for easy tweaking at all stages: correlation, acquisition, and navigation.Sat Mar 10 02:00:34 2012 - permalink -- http://fastgps.sourceforge.net/

Stanford GPS/GNSS Matlab Platform
Stanford GPS/GNSS Matlab Platform is an integrated research platform for utilizing numerous positioning databases. It is intended to function as a platform providing an universal access to various formats of GPS/GNSS data such as NSTB, NMEA, and RINEX. Example databases include the NSTB stations that collect GPS information continuously in tens of sites and web-available and open to public. According to the presentation (February 2009), RINEX was (is?) not implemented yet.Tue Apr 28 17:30:53 2009 - permalink -

A group at Cornell University decoded GIOVE-A signals
Using code-less acquisition techniques on the signal recorded using a sensitive receiver, they succeeded in determining the spreading code of the GIOVE-A spacecraft. Since the GPS signals are stronger, they were tracked and removed before. Analysis was donTue Jul 11 16:31:39 2006 - permalink -- http://gps.ece.cornell.edu/galileo/
