This is what I found for inmarsat :

Some 200 kHz channels and some 50 kHz channels.
There is also some 30 kHz channels with a small 'X' periodically in
the spectrograme. Those are GMR-1 and probably leak through from
Thuraya (either reflections off buildings, or my antenna polarization
sucks). Or maybe inmarsat has some GMR-1 carriers, but I doubt it.
Cheers,
