Latest Sentinel-1 data produced with IPF 003.40 (and 3.51?) after 2021-11-04 07:56:32 are not supported.

[S0sh0rt]

Running SentinelWrapper.py config_reference returns this message and does not complete successfully:

Setting IPF version to : 003.40 'utf-8' codec can't decode byte 0xc0 in position 10: invalid start byte

Check your downloaded zip files. Likely an incomplete download

I have used the same SLC files in S1TBX and GAMMA. The zip files also test without error.

Would be helpful if actual granule names are provided. Were these zip files repackaged user side? In that case, they could have been encoded differently. Also no environment is described .. so really hard to say what is causing this

CentOS 7 with a build from the latest ISCE 2.6 clone. zip files were downloaded from ASF, no repackaging. Files produced prior to 2021-11-04 process correctly. The files below result with invalid start byte, when running run_01_unpack_topo_reference from stackSentinel.py.

I had no issues working with one scene at least. Do you have a weird environment setup with PYTHONIOENCODING set to something specific or have weird characters in your folder names? 0xc0 is a character with an accent - not sure its standard ASCII

import os
import shutil
import isce  # noqa
from isceobj.Sensor.TOPS import Sentinel1

fname = "S1A_IW_SLC__1SDV_20220216T041150_20220216T041217_041933_04FE4B_4E5A.zip"
outname = "test"

for swaths in range(1, 4):
    if os.path.isdir(outname):
        shutil.rmtree(outname)

    parser = Sentinel1.Sentinel1()
    parser.configure()

    parser.safe = [fname]
    parser.swathNumber = 2
    parser.output = outname
    parser.polarization = "vv"
    parser.extractImage(virtual=True)

If you are on an international (non-english) language setup, try setting this env variable: https://github.com/isce-framework/isce2/blob/566ebfb9a85f2bdb5d538b3ba86b289aaaf702a7/docker/Dockerfile#L4

I am now also unable to reproduce the issue. It must have been something with my environment in the terminal I used for 2022 data, and not the terminal used for the 2021 data. Thank you for your support and prompt replies.

Hello, is there any good solution to the problem you encountered at that time? I have also encountered the same problem in the process of learning, and I would like to ask for your help.

[Xious-1314]

Hello everyone, I solved this problem by deleting the original track file and re-downloading it.
