    Hi,

    It seems to me that you’ve had your firewall on and blocked the outgoing connections to download precise orbit files from an external ftp site. Can you confirm that? If you do have a firewall on please try to close it and try again.

    If it is still not working I will add a line in the code so that when returning such an error when connecting to external sites for downloading orbit file the code will then read the built-in orbit file from S1A SLC files.

      Hi,

      An updated code was submitted.

      The reason you get this error is because yesterday both of the server for downloading orbit files were shut down and (not start running yet but will be). (And also because there’s a bug in the code not considering fully this situation.)

      One more word about S1A orbit file: In case there’s a connection error again in the future, all the orbit files for S1A is located in ORBITS/S1A/yyyy/mm/aux_zzzzzz/ where zzzzzz is [ poeorb | resorb ]. poeorb is the precise orbit and resorb is the restituted orbit. You can manually download them from https://qc.sentinel1.eo.esa.int/ if you want and place in the corresponding folder.

    As of now I again started using older version, please notify when code will be updated for dual option. download automatically or if download fail then use the older orbit info.

    the new version is online (pcodes and compiled for win)
    however, I believe that what Yuxiao is saying is always valid (not a new option): if the automatic download fails, download the files manually…

    For processing of S1A in sarproz, do the SLC images have to be in the same orbit track over the area of interest?

      Yes. SLC images need to have the same relative orbit track number.

      absolute orbit number can be read from the file name of your downloaded S1A, and

      relative_orbit = mod (absolute_orbit – 73, 175) + 1;

      Sorry, it seems to me that you’re using the compiled version.

      I’ve updated the code and we will update the compile version soon. Meanwhile (if you can) please switch back to the previous version (that should not have this error).

      Sorry for the inconvenience..

    In the previous version (i believe is 17 May), I am facing the coregistration problems (another user reported it as well). I will wait till your new compiled version comes out. thanks Yuxiao
