AIS Targets
AIS targets are all targets whose data are received by the AIS electronics unit connected to the system.
All AIS targets are visible per default after switch-on of the MFD.
The display of groups of AIS targets (Class A, Class B , All) may be switched on and off by the
operator. Select All if you want to see all targets received from the AIS electronics unit.
AIS targets can be of the following kind:
Table A / 11 Symbols of AIS Targets
Target Fusion
Due to the fact that an AIS target within the radar range normally also produces a
radar echo, the symbols of tracked and activated targets are displayed close to each
other:
In this case, it is possible to decide whether the object is to be treated as an AIS
target or as an ARPA target. See chapter 3.5.1 on page III-59 for details. In terms of
an improved display readability and avoidance of cluttering the screen, the objects can
be fusioned if they meet some boundary conditions. That means, that they can be
displayed only as either AIS or as ARPA target depending on user selection. See
chapter 7.7 on page A-65 for details on Target Fusion.
The number of ARPA and AIS targets being tracked should be kept as small as possible; the pres-
ence of too many targets causes confusion on the screen and distracts the operator's attention from
what is really important. Targets that are no longer relevant should be deleted (RADAR) or deacti-
vated (AIS).
AIS targets
A sleeping AIS target is a target that is displayed in the PPI. Its data
are evaluated and can be shown on demand.
A manually activated AIS target is displayed with detailed data such as
HDG, true scaled outline (if available in the received data set and the
PPI scale is large enough), ROT indicator, past positions and speed/
direction vector can be shown
An automatically activated target by the collision avoidance computation
or by a acquisition/guard zone
An activated AIS target, which is selected and whose data are marked
in the target list
AIS targets may have an ID displayed on the bottom right of the
symbol. The ID consists of the callsign or the ships name or the MMSI
depending on the settings in the target presentation menu.
Lost Target. If any of the above mentioned targets gets lost, a flashing
cross is superimposed above the target symbol.
For AIS targets the lost target alarm can be switched off in the Target
settings.
