Slight geolocation shift after multilook of S-1 GRDH product

Dear S1TBX developers,

geolocation_shift_GRD_with_multilook.xml (9.3 KB)
Within the ESA SEOM soil moisture project ( we encountered a problem with the geolocation shift after the multilooking of a S-1 GRDH product. It seems that S1TBX fails to assign correctly geocordinates of center of an upscaled (50x50 m) pixel. This results in shift of around single 50x50m pixel.

Thank you for any kind of comment.
