2.3 UAIS Key Functions
¾ Automatic identification of other UAIS equipped vessels.
¾ Self-organising control of access to the radio channels.
¾ Reception of data via the radio channels from other vessels and coast
centres.
¾ Transmission of own vessel data via the radio channels for use by other
vessels and coast centres.
NOTE: Two channels, A and B, are used for transmission.
¾ Storage of static data intended for automatic transmission via the radio
channels.
¾ Output of data received via the radio channels from other UAIS objects for
presentation on the minimum display.
¾ Determination of the position and motion of own vessel if the external
GNSS receiver fails by utilising the internal timing GNSS receiver.
¾ Application of GNSS differential corrections using information supplied
from a supplementary receiver.
¾ The application of GNSS differential corrections using information received
from a controlling station via the VDL (VHF Data Link) channel.
¾ The output of Built-In-Integrity Test (BIIT) information regarding the UAIS
status on the main (e.g. ECDIS) display interface, auxiliary (e.g. Pilot)
display interface and also the minimum display.
¾ Delivery to the display of bearings and distances to the vessels, calculated
from their co-ordinates, obtained via the VDL channel.
