Somewhat off-topic but it might help someone out: I've had a tough time finding, and using, files on the net containing raw GPS signal samples to be used with the various software-only (or software-mostly) GPS receivers out there. I finally got a file of data that works and have have posted it plus a description of the file format here: <http://www.jks.com/gps/gps.html> I've used it successfully with Andrew Holme's excellent homemade GPS receiver. Now on to building an actual RF front-end to get some real signals..
If anyone's interested, I could probably get some samples of raw bits from a triband (L1,L2, L5) single bit sampler. Sample rate is about 39 MHz. The way the hardware works, the largest file is probably around 60 million samples (about a second and a half's worth of data)
If you want to use the data in a publication, you'd need to credit JPL as the source of the data.
