position, navigation, and voyage information. Also associated with
each target are computed data to help determine the risk of a
collision.
The targets are contained within a
target list
. The
AIS
WatchMate
allows you to view the target list and also examine each target in
detail. By default, the target list is ordered by
priority
. You can
disable priority ordering if you wish. However, by viewing targets in
a prioritised fashion you can focus your interest on the targets most
likely to pose a collision risk first. Similarly, whenever a target
triggers an alarm you don't have to scroll to find it. The target is
displayed immediately with an indication of the cause of the alarm.
The
AIS
WatchMate
utilizes data from your vessel's GPS receiver to
assist you in determining the risk of a collision with each target.
Multiple targets are automatically and continuously tracked
simultaneously. Alarms are associated with each individual target
and when an alarm is muted for one target it does not affect any other
targets which might also trigger alarms.
The computed data for each target includes the following items. Note
that in order to compute this data your vessel's current position,
course, and speed are required. The
AIS
WatchMate
receives this
information continuously from your GPS.
If your GPS is not connected, or not providing valid navigation
data, then this information will not be computed or displayed. In
addition, alarms based on this information will not be triggered.
Range
The
AIS
WatchMate
computes the range
(distance in nautical miles) to each target
and displays it along with the target
information.
