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:

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.

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

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