I will capture the data and put it on my website.  I was thinking a 
50-100mS sample period would be good.  That would be 50-100 symbols of C/A 
code.  I'll also post the ephemeris data with the samples to allow a 
complete nav solution.

Great web site Krys and it looks like a good start to software GPS.  Very 
cool stuff.

It might take a couple days since I'm going through the USRP learning 
curve as we speak.
