Re: Galileo Frequency Shifting and Filtering

[It's a cat]

If you have a signal generator, GNSS simulator or a high gain antenna, you can verify your settings by adding a spectrum display (Qt Freq Sink) or something like that to your receiver path.

Because many things can go wrong in your setup, if you misunderstand something. Just try to verify this directly. If there's a signal you should be able to see it on the spectrum display.

Hi guys,

I am trying to simultaneously record Galileo's E5a and E5b signals as follows:

I have tried to record them separately by tuning the local oscillator in the middle of the signals bandwidths and sampling at 25MHz and it worked. But when I try to shift and filter to get the signals in a different file, it does not work. I have no idea what am i doing wrong.

Galileo's Signal Plan is as follows:
