Thank you. I would like to know the threshold point of the runway. Why? There are many satellites arround the Earth, 3 navigational systems. But if somebody to try the "blind" landing by GPS/GLONASS/GALILEO only (w/o ILS) , it's the disaster.
GLS actually is CAT IIIb capable, but not approved so far. So blind landing with that is completely possible, and the best bit is, you do not need an onboard database for that as the approach geometry is broadcasted by the groundstation. Which is of course the downside of it, it requires a ground station.
