Getting GPS data into stream

[Fabian Schwartau]

Hi everyone,

I am trying to record some data from an SDR and would like to sync/tag 
the data with the current gps position from gpsd. I am kind of stuck and 
don't know how a possible solution for that might look like in grc.
I have a python function that gets the current position as a tuple, but 
how do I get this into my data stream, which I would like to write to a 
CSV file or similar?
I am not asking for a solution of my problem, just point me in the right 
direction ;)

Best,
Fabian
