even when the radar picture is degraded by heavy precipitation or other interfer-
ence.
The AIS channels can be used to transmit port data, pilotage, berth assignments,
shipping agency information, tides and currents, notices to mariners and other
information from shore to ship, as well as ship-to-ship and ship-to-shore AIS
reports. It is also possible for the VTS to broadcast the complete harbor picture
to all ships in the area, so the masters and pilots all share the same “big picture.”
The VTS center can assume control over the assignment of time slots for AIS
messages to ensure optimum data exchange within the coverage area. Special
dedicated channels may be designated for local-area AIS operations. The ship-
board AIS equipment will have the ability to shift to different channels automati-
cally when directed by the shoreside VTS controller.
