On the QC website https://qc.sentinel1.eo.esa.int/

Thank You. But S1A ending 2015.
That this means? Foward from that date must be use last one?

The two dates within the file name for AUX_CAL files, e.g. S1A_AUX_CAL_V20150722T120000_G20151125T104733.SAFE, refer to the start validity date and the generation date. So if your S1A product was acquired after 20150722 at 12 noon, then the S1A_AUX_CAL_V20150722T120000_G20151125T104733.SAFE file is applicable to your product. This is also the most recent S1A AUX_CAL file. The generation date is just the date when the file was created.

Thank You :slight_smile:
