"... system to convert satellite imagery from its original (raw) format,

-> r.in.gdal

" ... through calibration, .."

-> r.mapcalc

"... pre-processing ..."

-> r.mapcalc

"... , atmospheric correction, "

-> i.atcorr

"... and cloud masking steps"

-> r.mapcalc with TIR channel(s)?

 " and then performs a Monte Carlo Spectral Mixture Analysis ..."

-> I had once written i.spec.unmix (GRASS Addons SVN), Monte Carlo stuff
is available in R (spgrass6 interface).

So, quite some pieces seem to be there.
