 `Fix` - Each row represents a [Location](https://developer.android.com/reference/android/location/Location), collected from the [Location API](https://developer.android.com/reference/android/location/LocationListener) (for `GPS` from the [`GPS_PROVIDER`](https://developer.android.com/reference/android/location/LocationManager#GPS_PROVIDER) and `NLP` from the [`NETWORK_PROVIDER`](https://developer.android.com/reference/android/location/LocationManager#NETWORK_PROVIDER)) and [Fused Location API](https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderClient.html) (for `FLP` from the [`FUSED_PROVIDER`](https://developer.android.com/reference/android/location/LocationManager#FUSED_PROVIDER)).

 `Agc` - Each row represents a combination of the [GnssClock](https://developer.android.com/reference/android/location/GnssClock) and [GnssAutomaticGainControl](https://developer.android.com/reference/android/location/GnssAutomaticGainControl) that are reported as part of a [GnssMeasurementEvent](https://developer.android.com/reference/android/location/GnssMeasurementsEvent). Note that there will be multiple AGC records (one per carrier frequency per constellation type - i.e., all satellites of the same constellation and same frequency have the same AGC), reported in [GnssMeasurementsEvent.getGnssAutomaticGainControls()](https://developer.android.com/reference/android/location/GnssMeasurementsEvent#getGnssAutomaticGainControls()), for each clock/event.
