Tracking Overload

- An alarm indicates

attempted acquisition of the 51st target. To track
an another target, requires one or more currently
tracked targets to be released from tracking.

(17)

Mapping

- External NAVCARD used for map

storage and retrieval. Several cards can be used
for multi-map storage. Each card can store
approximately 64Kbytes of features. Flexible
partitioning is arranged to store different maps.
Maps can be land stabilised in any mode and can
be stabilised by SATNAV or GPS. Auto map
positioning facility, uses smoothed ship’s position.

(18)

Drift Input

- Three modes of drift input; Manual -

True motion models only 0-99.9KT, GPS -
Ownship vector calculation (GPS Fitted) and Plot -
Autodrift calculation using reference targets.

(19)

Interfacing

- Target data (ARPA tracked targets)

outputs are available in IEC 61162 TTM format
and as a feed to a serial printer.

(20)

Automatic Identification System (AIS)

Adjustable 50 plot capacity.

Op tions

As detailed in the Introduction section of this manual,
except that the Additional NAVCARD external Maps

and Serial Comms Adapter Board are fitted to ARPA as
Standard.

ARPA PLOTTING CON TROLS

Ac quire Tar get

To manually acquire a target, position the cursor over
the target and press the

[ACQ]

Acquire pushbutton,

the target is labelled with a symbol. Within 12 scans a target
vector is generated and within 3 minutes the vector is stable.

Se lect

To select a target, position the cursor over the target
and press and release the

[Select]

pushbutton. The

target plot symbol and vector flash to acknowledge
selection. Once the target is selected, full target information
is available in the target data field provided that the target is
being tracked.

NOTE:

When the SELECT pushbutton is pressed the target vector
flashes.

De lete

Position the cursor on the target and press the

[Select]

pushbutton, press the

[Delete]

pushbutton and the

tracking/plotting on the target ceases. Targets causing a
collision warning cannot be deleted until acknowledged.

NOTE:

Ensure that the correct target, map or navigation line or
symbol is selected before pressing the DELETE
pushbutton.

Vec tor Mode

Change the vector presentation mode by positioning
the cursor in the Vector menu; press and hold the

centre pushbutton

[Mode]

for 4 seconds. The Vector box is

outlined in red to indicate that vectors are displayed in the
opposite presentation mode to that of the display, plus a Red
Warning box as below. To return the Vectors to the correct
presentation mode repeat the procedure, but only pushing
the button momentarily.

NOTE:

If the cursor is outside the radar area, the left pushbutton
gives direct access to vector mode without moving the
cursor into the vector box.

Vec tor Time

The vector time can be changed between 1 and 30
minutes, in increments of 1 minute, by pressing and

operating the trackerball in the vertical plane to increase or
decrease the time shown next to VECTORS in the
OWNSHIP DATA field.

The default or initial value of vectors is 15 minutes. The
length of the vector is proportional to the speed of the

target (e.g. target speed 12 knots (KT) then vector length is
3nm, which is the distance the target travels in 15 minutes).

Tar get Data

To display target data, position the cursor on or near
the required target/vector and press the

[Select]

pushbutton. The target plot symbols and vector flash; data
on the selected target is displayed/ updated in the TARGET
DATA field every scan.

NOTE:

Between acquiring a target and the ARPA generating a
vector, the TARGET DATA shows Range and Bearing
(BRG) only. Target course (CRSE) and speed are ‘True’.

To vary either the

[CPA LIMIT]

or the

[TCPA LIMIT]

select the function and press and hold down the left

pushbutton, operate the trackerball in the vertical plane to
increase or decrease the limit value. Press the centre
pushbutton to enter the minimum (MINIM) value and the
right pushbutton to enter the maximum (MAX) value.
