Target Display
The target display screen is shown when you select a target from the
target list or situation display. This screen contains detailed
information about the target. The information displayed will vary
depending on how much data has been received from the target and
the type of target.
AIS data for a target is received in several types of messages and
those messages may be received at different times. The interval
which a target sends messages is based on the type of message, class
of target, its speed, rate of turn and other factors. As a result certain
information may not be available immediately from a target.
However, the
AIS
WatchMate
displays available information as soon
as it has been received. If you are viewing a target when new data
arrives for that target, the screen is refreshed with the new data.
Until voyage information has been received for a target, its name is
- 36 -
