if it uses the growing number of satellites with a dedeicated AIS receiver, is it not technically S-AIS?
If VHF only then it is definitely LOS.
Technically all satellite comms involves at least two LOS segments, but generally satcom is considered BLOS.
AIS is VHF, and is relayed through satellites giving the system BLOS capability.
For ships there is no impact on installation, for aircraft the obvious has to be considered.
