You're probably referring to "usrp_fft.py", which gets installed into

This is Great work.
It sound like you've got GPS working for the most part. And in a
multi-threading way. Which is very good.
Is the gps-sdr work-in-progress code available anywhere yet. I could only find

Hi Paul,
Finally I got a working system of USRP radio. The FM radio example runs
smoothly (atleast opens up and captures nothing:giving errors like
"usb_control_msg failed: usb_control_msg failed: sending control message

That is a great reference book. The Matlab code actually works and
generates a fix. Here is a link to some Over The Air captures, including
GPS.

Hi Faisal,
I'm also working with GNU Radio for GNSS applications. A good start could be
a recording of samples into datafiles and then post-process the data in the
way that you feel more comfortable (the book [1] comes with a DVD with a
complete GPS L1 receiver implemented in MATLAB, all GNU code)
Faisal,
I'm at Purdue University working toward using the USRP for GNSS
applications. Check my understanding: are you wanting to use the USRP
to record, say, L1 band samples directly to a data file? Would you be
