 |       `if_bw`        | Set the bandpass filter on the radio frontend, in Hz. It defaults to `0` (automatic selection). This feature is present in GNSS-SDR v0.0.18 and later versions.                                                                                                                                                                                                                                                 |   Optional   |
 | `sampling_frequency` | Sampling frequency, in samples per second. It defaults to 2 Ms/s.                                                                                                                                                                                                                                                                                                                                               |   Optional   |
