We have i.atcorr: http://grass.itc.it/grass64/manuals/html64_user/i.atcorr.html but it apparently lacks SPOT 5 HRV. If you could find the filter functions for us, we can rather easily implement support. For terrain correction, see http://josef.fsv.cvut.cz/WIKI/grass-osgeo/index.php/Image_processing#Correction_for_topographic.2Fterrain_effects The cosine correction can be implemented with r.mapcalc.
