You are making the assumption that an autonomous airliner would use 1950s tech autoland.
Why on earth would a future aircraft even consider such archaic tech as ILS/MLS/VOR/NDB? We only use it today because it is certified despite the fact that VOR and NDB approaches have awful safety statistics.
There are 1000's of better options if you are already making the jump to entirely new certifications.
