INPUT OF REGIONAL SETTINGS
In each area, numbers of VHF channels are set by the Administration. Beyond the
regions, the AIS equipment uses channels 2087 (AIS1) and 2088 (AIS2) with a
bandwidth of 25 kHz and power of 12.5 W. As a mobile object is approaching the
region, the AIS mobile equipment receives numbers of TDMA VHF channels in one
of the following ways:
•
from the coastal AIS equipment;
•
from the coastal DSC equipment (where the AIS and DSC are used jointly in
the area);
•
from the AIS administrator by manual input (backup method).
One of the main functions of the AIS Base Station is to transmit information on the
