Recently, ESA released a small test dataset for the new Sentinel-1C satellite, which I am currently testing. However, I noticed that when I try to perform orbit correction (Apply-Orbit-File), the processor attempts to retrieve orbit files that don’t exist yet.
Do I need to configure the orbit correction differently, or is this simply because the required orbit files are not yet available? The processor is trying to fetch the following orbit files:
Hello, I also encountered this problem when using snap processing for radiation correction:A problem occurred during the target product initialisation.
Type: OperatorException
Message: Mission SENTINEL-1C is currently not supported for calibration.
What software or method did you use to pre-process 1C data?
Hi Naomili! I use GPT to apply orbit files, directly after reading them. The issue with calibration has already been reported here: Sentinel 1C Data and will be fixed in SNAP 12 according to this Jira.
Do you know how to use or configure snap3939? Please help me, I’m new to this
Jira ticket SNAP-3939 created. The update will be available in the next release.
SNAP-3939 is just the name of the ticket, the fix will added to SNAP version 12. So you just have to wait until the release of SNAP 12 and install that then. It might be better to ask these questions in this forum post ‘Sentinel 1C Data’ since that question is about the calibration issue and this question is about orbit files
Dear @simonvb00
The orbit files are sourced from Copernicus Dataspace. As they have not yet been made available there, they are also unavailable on the STEP server.
The precise orbit files for S1C are not yet available. When they do become available the apply orbit operator should work with them without an update.
For the calibration of S1C, an update is needed and should be available soon.
