    Hello,
    I am getting error in downloading Sentinel precise orbits. So I followed the steps from link below.
    https://www.sarproz.com/groups/sarproz-group/forum/topic/sentinel-orbits-in-sarproz/

    After Downloading Precise orbits from https://qc.sentinel1.eo.esa.int/ and placed in ORBITS/S1A(S1B)/yyyy/mm/aux_poeorb(aux_resorb)/*.EOF. aux_poeorb I returned to the SLC data import process. But SARPROZ is not able to read precise orbits that I downloaded and placed. Please help me with the issue.
    Thank you.

    Did you “set orbits” again after you downloaded the orbits manually and placed in corresponding folders?

    Please note that S1A(S1B) means either ORBITS/S1A/2018/05/…. or ORBITS/S1B/2019/12/….

    If it still does not work please print-screen me the path of the orbits.

      Dear Yuxiao,

      I tried “set orbits” after placing manually downloaded orbits in corresponding folder. Please find the attachment of screen shots below. Did I download the wrong file ? For S1B product S1B_IW_SLC__1SDV_20161007T051857_20161007T051924_002396_0040C9_0BD2.zip
      I downloaded precise orbit S1B_OPER_AUX_POEORB_OPOD_20161007T112543_V20160916T225943_20160918T005943.EOF
      Still sarproz cannot read precise orbits.

      Thank you.

      In your data:

      20161007T051857_20161007T051924 means the data is taken at 2016-10-07 05:18~05:19 UTC.

      In your orbit:

      20161007T112543_V20160916T225943_20160918T005943 means the orbits cover the period from 2016-09-16 22:59 UTC to 2016-09-18 00:59 UTC. 20161007 merely means the date that this orbit file is released (usually 21 days after the data acquisition).

      Dear Yuxiao,
      After Downloading and replacing with correct orbits it worked.
      Thank you.
