The aviations system is named ADS-B, see the link below:

Please, I am focused here in the HOW this will be done, not in the IF,
since my initial question assumed that Garmin will unveil soon a
compreensive solution on AIS, probally launching new "sensors": an
AIS transponder Class B, wich specification as not yet finished by
IMO/ITU, and a more simple receiver, that would be supported on its
line of Gps Chart Ploters, or pheraps, others AIS standalone units.

So am asking that We return to the How side of the question, thanks.
