Real AIS AtoN
A physical navigation aid on which an AIS transmitter is mounted and from which AIS messages are sent.

TDMA ACCESS SCHEMES
RATDMA
Random Access Time Division Multiple Access
This access scheme is used when a station needs to allocate a slot, which has not been pre-announced.
FATDMA
Fixed Access Time Division Multiple Access
This access scheme is manually managed. The AIS devices are pre-configured to use specific TDMA (Time Division Multiple Access) slots for all transmissions. FATDMA is used only for AIS base stations and AIS AtoN stations.
