How to orthorectify S1 data

Hi everyone,

for the orthorectification of S1 data, is the terrain correction sufficient ( i mean as the final block of preprocessing)? or should something more to be added?
I searched in the tutorial section but I did not find anything ( some links are corrupted)
probably @lveci or @ABraun could tell me more :wink:
Thanks in advance!!

Usually, terrain correction and geocoding are the last steps to be performed. They include resampling of the pixels into a new coordinate reference system but I would already apply the speckle filter before.
