Inmarsat B
Das Inmarsat B benötigt eine grosse Satellitenantenne und kommt
deshalb auf Segelbooten nicht zum Einsatz.
In der LRC (Long Range Certificate) Prüfung werden einige
systemvergleiche Fragen zu Inmarsat B und Inmarsat M gestellt.
Beide stellen wie im Telefonnetz eine Verbindung zwischen den
Teilnehmern her, das Inmarsat C arbeitet dagegen nach dem Store
and Foreward Prinzip – ähnlich wie der email Transport im
Internet.
