      Hello Yuxiao, thank you for this great update.
      I takes a couple of weeks for precised orbit files to arrive, does it mean, that new co-registration method can’t be used with newest images?

        Sure, a have attached a sample kml file.
        Thank you!

          Hello,
          The problem has really gone by itself. Thank you for assistance.
          If this kind of error happens again, do I just wait a couple of days for this error to be gone?

            Sorry for late response.
            The of the file, i have found there: S1B_OPER_AUX_RESORB_OPOD_20171001T085309_V20171001T040012_20171001T071742.EOF

              Tenth directory was empty, however I suggest, that you kept in mind ninth one.
              There was only one file: S1A_OPER_AUX_RESORB_OPOD_20170925T091232_V20170925T040053_20170925T071823.EOF

                Hi Yuxiao,
                Doesn’t master choice influence co-registration process a lot? I have often noticed, that outcome may be significantly improved just by choosing right master.
                Additionally, I’d like to ask about Sentinel master choice methodology. Usually, master is chosen such, that the dispersion of the perpendicular baseline is as low as possible, but Sentinel already has small baseline difference. So can the baseline dispersion be ignored? What master choice criteria may be more influential?

                  Hello,
                  I didn’t actually completely overcome this issue yet.
                  However, the master choice seems to help sometimes. In cases of problematic co-registration I usually try to manually evaluate image list in order to exclude the most noisy ones and choose the most contrast image as a master.
                  Somebody, correct me if I’m wrong, please.

                      Hi Yuxiao,
                      I have updated the software, but problem still exists. Once I delete orbit files for some month, I will get errors for every image from deleted month. Broken orbits seem to be downloaded.
                      I can generate last error and log files for each case, if needed.

                        Hello,
                        Excuse me for late response. I have added missing log file.
                        Deleting the orbit file from ORBITS/S1A/MM didn’t help. Moreover, every image failed, if I had deleted its orbit file. I am also including last error file with log for error, that occurred after deleting an orbit file.

                          Hi Yuxiao,
                          I just got an advice, that oversampling could improve the results, and could not though, so I wanted to try it.
                          Since it’s neither likely to help, nor supported in SARPROZ, I don’t see a reason to raise a dust.
