2.20 ATA
To use the ATA, install the optional ATA board.
The ATA automatically tracks targets and stores
and displays their courses and speeds as
vectors.
Entering the heading bearing and ship speed are
required, using the optional GPS compass or
others.
After tracking, targets are displayed as a vector
of course and speed.
An object, which is acquired and tracked, is
called a target.
To activate ATA, the bearing and the speed
information of own ship needs to be input.
The bearing signal shall be such high speed and
highly accurate signals as from GPS COMPASS.
GPS bearing only tends not to be enough to
operate ATA normally.
Automatic Acquisition
Targets entering in the preset range can be
automatically acquired.
1 Press the [MENU] key.
2 Select [ATA] → [AUTO DETECT AREA].
3 Change the setting of [AUTO DETECT
AREA] with the [ ] and [ ] keys.

4
After selecting ON, press the [ ] key. Then,
the automatic acquisition range can be set.
5
After moving the crosshair cursor to the
center of [AUTO DETECT AREA] with the
[ ], [ ], [ ] and [ ] keys.
6
Press the [ENT] key.
7
Change the distance with the [ ] and [ ]
keys and bearing with the [ ] and [ ] keys.
8
Press the [ENT] key. Then, the [AUTO
DETECT AREA] is set.

Press the [MENU] key to close the menu.
As the ATA is optional, the menu
becomes valid only when the ATA
board is installed.
Caution
Warning
The accuracy of the data provided
by the AIS could be affected by the
following factors:
Degraded bearing data and
latitude/longitude from external sensor
devices cause erratic vectors. If any error
data fed from external sensor devices are
detected, the following data provided by the
AIS display will be also erratic.
- The CPA and TCPA value and Alarm.
- The target ship’s course and speed.
- The target ship’s bearing and distance.
Warning
The accuracy of the auto tracking
function provided by the ATA could
be affected by the following factors:
(1) Sea clutter and weather clutter such
as rain and snow may degrade the
ATA tracking capability. These clutter
components should be appropriately
reduced.
(2) Poor receiver sensitivity may also
degrade the tracking capability.
(3) Faulty azimuth synchronization could
be the cause of erratic vectors.
(4) Degraded bearing and speed data fed
from external sensor devices also
cause erratic vectors.
If any of the errors stated above are
detected, the following data provided
by the ATA will be erratic.
- The CPA, TCPA value and Alarm.
- The target ship’s course and speed.
-
The target ship’s bearing and
distance.
