 ## About CygnusRFI
-**CygnusRFI** is an easy-to-use **open-source** Radio Frequency Interference (RFI) analysis tool, based on [Python](https://www.python.org) and [GNU Radio Companion](https://wiki.gnuradio.org/index.php/GNURadioCompanion) (GRC) that is conveniently applicable to any ground station/radio telescope working with a GRC-supported software-defined radio (SDR). In addition to data acquisition, CygnusRFI also carries out automated analysis of the recorded data, producing a series of **averaged spectra** covering a wide range of frequencies of interest. CygnusRFI is built for ground station operators, radio astronomers, amateur radio operators and anyone who wishes to get an idea of how "radio-quiet" their environment is, using inexpensive instruments like SDRs.
