Sentinel 1C Data

snap
1

Earlier this week some sample data from Sentinel 1C became available through the CDSE APIs. Our system automatically picked it up, but perhaps as expected, SNAP failed to process it and stated 1C is not supported. Is there an update for 1C available please? Couldn’t see anything in the changelog. Thanks.

Here’s the errors:

Jira ticket SNAP-3939 created. The update will be available in the next release.

3

Thank you. When is the next release scheduled for please?

4

Helo diana, I am student in university, and I research abut snow dept by Interferometry of Sentinel1 SLC and I have problem about Unwarp processing and Presidion of processing. Can you help me?

5

SNAP 12 release is planned for the end of Q1 2025

6

@jun_lu could you help?

7

Here (Tutorials – STEP) you can find many interferometry related tutorials in which detailed processing steps are given. Hope they will be helpful to you.

8

thank you for reply, but I don’t know how to use the" SNAP-3939 On GitHub"
can you show me? thank you very much

10

The update will be available in SNAP 12.

11

@diana_harosa S-1C is already in space, so this should be fixed with a module update asap.

12

Hi @diana_harosa. Is SNAP 12 still on track for release at the end of the month?

13

Dear @markcorbin,

SNAP 12 is in the testing phase, and we are confident that it will be released by the end of the month.

14

I failed to create a STEP issue (bug report) for SNAP 11. How to ? I didn’t find anything to create one.

Could you help me ? A step-by-step processus is welcome.

Thank you.

Dear @Laurent-777 ,

You can report the issue on the STEP forum by providing :

  • The error message
  • The exact processing steps needed to recreate the issue (if you are using a batch, a python script or a GPT graph file, please attach it to your post)
  • The SNAP log file generated after reproducing the issue (you can find it by selecting from the menu Help / Show Log Directory)

See FAQ - STEP Forum for more details on how to report an issue.

Hi @diana_harosa. Is SNAP 12 now available please? I see that ESA have starting supplying Sentinel 1C data via the CDSE API and we currently have no way of processing it. Thanks.

Dear @markcorbin,

SNAP 12 is noy yet available, but Microwave Toolbox 11.0.1 has been deployed last week. This update includes S1C calibration and orbit file support.

Thanks we will try that. Is there a new timeline for SNAP12?

19

Somehow I am still getting the No valid orbit file found and Unable to connect to http://step.esa.int/auxdata/orbits/Sentinel-1/RESORB/S1C/2025/03/ warnings with updated SNAP 11 Microwave Toolbox 11.0.1.

On a related note, is there a way to find out the toolbox version via the command line?

20

Attempting to answer the second part of my question: is it by snap --modules --list and check for the version number for those starting with eu.esa.microwavetbx?

Hi Tim,
Thank you for reporting this issue. We are currently investigating why the RESORB are not available for download.
