Orbit file timeout (March 2021)

Thanks mengdahl. Indeed, snappy normally reverts to restituted orbits when precise orbits are not available… however in this case it appears that it is unable to find both the precise and the restituted orbit data.

Had you did any updates in SNAP 6? You should not do any.
Try and let us know

Hey guys !

Should we submit a ticket for this ? I don’t know if it has already been done …

if someone can provide short description on what exactly is broken (based on your discussions above), I’ll create an official ticket for you.

thank you, an official ticket has been created here: https://senbox.atlassian.net/browse/SITBX-842

How about the API previously located at https://qc.sentinel1.eo.esa.int/api/v1/? Has it been relocated, or discontinued?

That API is no longer available. In addition ftp://aux.sentinel1.eo.esa.int/ is not currently updated.

However, the most recent orbits on https://aux.sentinel1.eo.esa.int/ were created on February 25, even for PREORB. There are currently no orbit files available for any S1 product that was taken after 20210225T184102 (PREORB), 20210225T120558 (RESORB) or 20210206T005942 (POEORB). So that is about 6 days behind for restituded orbits (which should be a few hours), and almost a month for precise orbits (which should be about 20 days). So if https://aux.sentinel1.eo.esa.int/ is supposed to be the authoritative and main channel for orbit files, than could someone please make sure they’re getting updated in time (or prove me wrong)?

I have the same problem

connection timed out

I have the same problem for applying orbit file, the connection timed out

Hi guys, I have the same problem for applying orbit file during today.
Last one, I have uninstall SNAP 8.0 then indeed has been tried download previous version (windows 64bit all toolbox SNAP 7.0) from ESA official site, unfortunately but couldn’t it. So think maybe have problem on server ESA.

Thanks for helps @mengdahl. I should process hundreds of data in snappy, so it is difficult to use one by one for any data.
I downloaded all orbits from here


Is there any way to implement orbits in files to work directly through snappy?

In all these links, the dates stop at 25 February 2021 for PREORB and RESORB. After that, there are no available orbits .

yes I know but at least we can work for previous data…I hope it can be solved for recent data because we need them

There’s a fix coming which will be able to get the orbit files from other sources.

Thank you so much Iveci, May i know when it will come?

Ok I have updated information from the S-1 PDGS (Payload Data Ground Segment):

There is currently an anomaly that has stopped the updating of orbit files on scihub - this issue is expected to be resolved shortly.

Hi all,
is there any API to get the orbit files from the new official source?

There shoud be, see the guide:
