How to Geocode and georeference ALOS PALSAR PLR SLC L1.1 Data?

[ABraun]

some ESA products have been reported to cause problems in SNAP, please have a look here:

Ellipsoid Correction of ALOS PALSAR L1.1 4pol data in SNAP not supported?

did you check if the same file is also available at ASF vertex: https://vertex.daac.asf.alaska.edu I read that the formats slightly differ, maybe this is one of the outcomes of that.

If you have the chance to check, please test a PLR SLC L1.1 product from ASF vertex to see if it is caused by the file structure of ESA.
