VIRGO: An open-source Spectrometer for Radio Astronomy

Hi all,

I just released VIRGO: An open-source Spectrometer for Radio Astronomy

VIRGO is an easy-to-use open-source spectrometer and radiometer based on Python and GNU Radio Companion (GRC) that is conveniently applicable to any radio telescope working with a GRC-supported software-defined radio (SDR). In addition to data acquisition, VIRGO also carries out automated analysis of the recorded samples, producing an averaged spectrum , a calibrated spectrum , a dynamic spectrum (waterfall) , as well as a time series (power vs time) plot.

PICTOR is also based on the VIRGO spectrometer.


You can download and install VIRGO here: https://github.com/0xCoto/VIRGO


As always, feedback and criticism is welcome and encouraged! :slight_smile:


Cheers,
Apostolos


Special thanks to Cees for his initial contributions to the software!

@0xCoto,

This looks great. Do you have any suggestions for open source hardware to use with VIRGO? Not just the SDR, but the whole setup. Thanks!

Happy hacking,

Jeff

Hi @jebba,

I’ve written a PDF discussing the construction of a radio telescope: https://pictortelescope.com/Building_your_very_first_Radio_Telescope.pdf

If you have any specific questions in particular, I am always happy to help!

“Building your very first Radio Telescope”

That’s about the best intro document I’ve ever read. I don’t see a license on it though, I suggest what the Libre Space Foundation uses for documentation, the “Creative Commons Attribution Share Alike 4.0”

Thanks!

Cheers! I’ve used the MIT License in the repository the PDF can be found: https://github.com/0xCoto/VIRGO/blob/master/LICENSE

The MIT License has actually got fewer/less-strict conditions and limitation compared to CC Attribution Share Alike 4.0, and as the author, I am okay with that.
