Using Radar > Apply Orbit File in a graph, I select Sentinel Precise (Auto Download)and expect the system to download the files automatically.

I can see processor tries to download http://step.esa.int/auxdata/orbits/Sentinel-1/RESORB/2016-11.zip but this is not found, in fact, this repo has no files since 2016-09.zip.

Now, is this repo discontinued (and the corresponding SNAP function broken)? I can see that up-to-date orbit files do exist https://qc.sentinel1.eo.esa.int/aux_resorb/?page=1 but “Auto Download” apparently looks only in the zipfile repo.

Can you update to the latest version of SNAP? It will download orbit files per file instead of by month and will get any missing files from the QC website automatically.

Thanks, @lveci,

but I already have SNAP version 4.0.0 and just updated all plugins.

Still:

Is this a problem with my installation? It is a clean install of SNAP v. 4.0.0 (i.e. not an update) and I am using a GPT file with this tag for Apply-Orbit-File:

  <node id="Apply-Orbit-File">
    <operator>Apply-Orbit-File</operator>
    <sources>
      <sourceProduct refid="Read"/>
    </sources>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <orbitType>Sentinel Precise (Auto Download)</orbitType>

      <continueOnFail>true</continueOnFail>
    </parameters>

I’ve updated the monthly orbit zip files for older versions of SNAP. However, the latest version will download orbit files individually and if not found on the server will get it from the QC website.
