In order to start using GNSS-SDR, you may want to populate ```gnss-sdr/data``` folder (or anywhere else on your system) with raw data files. By raw data we mean the output of a Radio Frequency front-end s Analog-to-Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz). Prepare your configuration file, and then you are ready for running ```gnss-sdr config_file=your_configuration.conf```, and seeing how the file is processed.
