OK Moritz, thanks for the comment. <br>
While the linewise ortho-rectification of satellite data is not
implemented, do you know another open source solution to perform
this task?<br>
<br>
Thanks,<br>
<br>

Hi Josep!

Now I need to do a geometric correction of this scene, not

<br>
Of course it is possible. Please, get your grip on the
respective GRASS-wiki
<br>
page and the related manuals.

i.ortho.photo is used for aerial photography, not for satellite
imagery. There is currently no orthorectification of satellite
images in GRASS. It is on the ToDo list though:
