Sure, you need to filter, and frequency-shift, and potentially resample.
What's the sampling rate your GNSS software expects?

Hi Marcus,
Thank you for your very prompt response. I have changed that but it still
does not work. Do you know if it is possible to separate the two bands
after the UHD: USRP block?

H David,
that makes no sense – from the figure, you would need to capture 50 MHz
of bandwidth. So, you will need at least that as sampling rate.
Your Bandwidth setting makes no sense, either, unless it's less than the
sampling rate (in general, just leave that field empty, and UHD will

Hello Ali Mahbas:
The gr-doa OOT currently only supports the USRP X300/X310 and the TwinRX

Dear all,
I need to do the angle of arrival by using USRP (gr-doa) and I know that this
example requires X310-TwinRX. Unfortunately, I only have X310-SBX, B210 and
N210-CBX. Would be possible to use any of these USRPs instead?
Any help would be much appreciated.
Thank you very much in advance.
You can hit breakpoints in the C++ code using VS Code:

Hitting the python called from a running flowgraph is not as

hi, all,As you know, GNU Radio will generate python file and execute. And probably it will not work correctly at the first time. So we need to debug. My question is about the debug method:1. Is there a way to add break point in python file (or C++ file)?2. And how about wa
Hello everybody!
I have just found out the "Single Pole IIR Filter"
of the gnuradio core library does not provide the possibility to set a
complex pole.
Is there a specific reason? Which is the best way to
realize this functionality without exploiting the more complex "IIR
Filter"?
Thanks for

I have a problem when trying to measure noise/signal power. I have been
