It seems there was an issue accessing or downloading the required auxiliary attitude and ephemeris data needed by the modis_GEO.py tool to process the MODIS geolocation.
A few things to try:
Check your network connection and make sure you have access to the internet and the URLs used to fetch the auxiliary data. The error indicates it failed to establish a network connection.
Try running modis_GEO.py again with the "--verbose" option to get more detailed output on what URLs it is trying to access. See if those specific servers/files are accessible.
Use the "--ancdb" option to point modis_GEO.py to a local directory containing the attitude/ephemeris data instead of downloading it. You may need to manually obtain these files for the given date range.
There could have been a temporary issue on 9/20 with the servers hosting the auxiliary data. Trying a different date may work if the network itself is okay.
If the network itself seems fine, it's likely an issue with the availability of the specific attitude/ephemeris files on 9/20. Providing modis_GEO.py access to those files locally through "--ancdb" should allow the geolocation process to complete.
Let me know if the additional troubleshooting details help resolve the problem or if you have any other questions!
