When I use testGeogrid_ISCE.py, it puts the error "Error with orbit interpolation".
The output infomation is as follow:

Error with orbit interpolation. 

This error message, I don’t know how to solve it. How can I continue processing?

@SiriusXCH0103 can you post 1) the actual commands, 2) which type of data you used, and 3) how you preprocessed? without the detailed info, we cannot help to diagnose the root cause of that error

Thanks! I was going to process Sentinel-1 images with ISCE2.
I processed using the command:
testGeogrid_ISCE.py -m ../reference -s ../fine_coreg -d ../dem/demLat_S09_S08_Lon_E115_E117.dem.wgs84
of which "reference" and "fine_coreg" dirs are generated by ISCE2 processing "topsApp.py tops.xml".
Then it put the error message above.

@SiriusXCH0103 try using -m fine_coreg -s secondary for Geogrid, where fine_coreg has the orbit geometry info for the coregistered common part between reference and secondary. Secondary is only used for reading the date/time of the second acquisition.

when running autoRIFT, use -m merged/reference.slc.full -s merged/secondary.slc.full

@leiyangleon Thanks very much! I have tried your method, but it doesn't work. The same error occurs. I don't know if it's my installation problem or the data problem.
I'm going to re-install the software and try other data.
