I am running “Apply orbit file” in SNAP for Sentinel-1 data from March 2021 and April 2021. To run the processing offline, I would like to download the orbit files to my ~.snap/auxdata/Orbits folder.
However, there is only one orbit file available at http://step.esa.int/auxdata/orbits/Sentinel-1/POEORB/S1B/2021/03/ and there are no orbit files at http://step.esa.int/auxdata/orbits/Sentinel-1/POEORB/S1B/2021/04/.
Is there any other online source of the orbit files for March 2021 and April 2021 that I could use?
Hello,
The orbits from http://step.esa.int/auxdata/orbits/Sentinel-1/ were taken from https://aux.sentinel1.eo.esa.int which stopped working in March.
Now, for Sentinel orbit files, the primary location is the GNSS hub.
Maybe @lveci knows more.
Thanks, now I am able to find the required POEORB orbit file, the GNSS hub address is: https://scihub.copernicus.eu/gnss/#/home (I had to log-in as guest to be able to do the search)
