AIS and radar target association

When an echo with its AIS symbol on top is being acquired for tracking, the system can detect that the two symbols represent the same target with the target association function. When the function is activated, the radar target and the AIS target are associated. You select whether to use source data from the AIS target or from the tracked radar target.

Associated targets - using AIS data Associated targets - using radar data

This function is useful for reducing the number of AIS symbols and radar targets on the PPI. Too many targets could clutter the screen and result in dangerous situations. The function

Targets | R5000 Operator manual

also compensates for a possible failure in one of the two targets, e.g. if the radar tracked target is positioned behind an island, the system keeps tracking and visualizing the AIS target.

Note: The tracked radar target continues to be analyzed by the system when the target

association is active.

Displaying target information

The vessels dialog

The vessels dialog displays a list of all AIS and MARPA targets. By default, the dialog lists targets, arranged by distance to own vessel. You can select to

change the sort order, and to display only a selected target type. The vessels dialog also lists received AIS messages. To display the vessels dialog:

• select the data option in the menu

• press and hold the AIS key

AIS vessel details

Detailed information about an AIS target is available from the AIS vessels details dialog. To display the dialog:

• select the AIS additional information option in the target menu

• select an AIS target in the vessels dialog

Training simulator

The training function is used to train the operator on manual radar target acquisition, on target selection and on the tracking procedures.

The function is activated from the menu. When started the system replays a pre-loaded file, simulating a target with constant speed

and course approaching own vessel. The training target's speed is as per the pre-loaded file, and it cannot be altered by the user. The CPA and TCPA depends on the simulated target's speed and own vessel's speed.

A flashing S is shown on the lower part of the screen as long as the function is active to warn that training simulation is running.

You can perform all tracking operations on the simulated target. The CPA and TCPA of the training target is automatically tested by the system. Alerts are

raised in case of a malfunctioning of the tracking software:

• Training Tgt CPA Out of Range: if the difference between theoretical and target displayed

CPA is greater than 0.5NM

• Training Tgt TCPA Out of Range: if the difference between theoretical and target displayed

CPA is greater than 30sec

The radar will return to default operation as soon as the training option is turned off from the menu.

Navigation tools

Tracking zones

The tracking zone function allows for automatic acquisition of radar and AIS targets when they enter a user defined zone ahead or around your vessel.

Two tracking zones can be defined, each with individual settings. When a target enters a zone, it will automatically be considered as safe or dangerous based

on the CPA/TCPA settings. Two types of tracking zones are available.

Guard zone

When a target enters a guard zone the following happens:

• radar targets are acquired and AIS targets activated

• warning about new target and warning about target being in zone are activated

• the target icon turns red and flashing

When the warning about new target is acknowledged, the icon stops flashing. The icon remains red until the target leaves the guard zone.

The color of the border line of a guard zone is defined by the user.

Auto acquisition zone

When a target enters an auto acquisition zone the following happens:

• radar targets are acquired and AIS targets activated

• warning about new target is activated

• the target icon turns red and flashing

When the warning is acknowledged, the target change to basic target icon and color depending on its status (save or dangerous).

The border line of an auto acquisition zone is white.

Defining a tracking zone

1 Turn ON the tracking zone you want to define

• The tracking zone lines are displayed on the radar PPI

2 Select the adjust option

Note: The line color is only applicable when the type is set to guard zone. The line color

is always white if the type is set to auto acquisition.

5 Save the changes by selecting the finish adjusting option in the menu

Note: If you exit the menu by pressing the exit key, the zone remains in edit mode. The

lines remain with dashed lines, and the zone is not active.

Parallel index lines

Parallel Index (PI) lines are used to visualize the distance to own vessel, other vessels or to land objects. Two index lines can be used to indicate a corridor - typically used to visualize an area you want to maneuver within.

The PI lines can be defined with north or heading stabilization, and with true or relative bearing.

• North stabilization: the line direction is maintained with respect to north

• Heading stabilization: the line rotates with the vessel heading

• True bearings: the parallel index bearing is measured from the geographical north

• Relative bearings: the parallel index bearing is measured from the heading line

You can define four PI lines in the system, and they are identified with different color and style:

• PI1: Grey solid line

• PI2: Grey dashed line

• PI3: Orange solid line

• PI4: Orange dashed line

You can turn each PI line on and off individually, and the position, bearing and truncating can be set for each line.

Each PI line can be reset to be parallel to own ship's heading from the main menu.

Adjusting a PI line

Each PI line's range and bearing are shown in PI lines submenu. You can adjust the line's settings from the selected line's Adjust menu option. The options

described in the next sections are available.

Adjusting range and bearing

1. Select the range or bearing menu options

The slider bar is displayed

2. Turn the rotary knob or use the up/down arrow keys to increase or decrease the slider bar

Line truncated

A line remains truncated until the restore length option is selected from the menu.

PI line alignment

A PI line can be parallel to port or starboard of the heading line, or to the port or starboard side of an EBL.

• If the stabilization is set to heading, the PI line rotates as the vessel heading change

• Parallel to EBL is a way to quickly set the bearing of a PI line parallel to the EBL in use. The

line does not rotate if the EBL is changed later.

EBL/VRM markers

The EBL/VRM markers are a basic tool for collision avoidance. They are used to mark any fixed or moving radar target, and to measure distances between two objects.

The reference point of an EBL/VRM marker is by default positioned at the center of the vessel. It is possible to offset the reference point to any selected position on the radar image to measure the distance between two objects on the PPI, or to fix the marker to a target.

Two different EBL/VRMs can be placed on the radar image. They are identified as dashed rings/lines with different colors to discriminate them from each other and from the fixed range rings:

• EBM/VRM1 is cyan

• EBL/VRM2 is blue

The EBL presentation can be defined with true or relative presentation:

Navigation tools | R5000 Operator manual

• True motion: the reference is geographic (e.g. a coastal line or current own vessel position)

• Relative motion: the EBL follows a moving reference (own vessel or a moving target)

The marker's line width indicates whether the marker is in edit mode (bold lines) or at a fixed position (thin lines).

Measuring range and bearing

Different options are available for measuring the position, speed, course, distance and bearing of radar echoes.

• Cursor position

• Range rings and bearing scale

• EBL (Electronic Bearing Lines) and VRM (Variable Range Markers)

It is important to minimize the range to obtain the best precision for the measurement. In most cases you can use a higher range if you position the PPI in one of the off-center modes. Refer to "Offsetting the PPI center" on page 31.

Note: Every measurement made with cursor or EBL/VRM is always referred to the

Consistent Common Reference Point (CCRP).

Using the cursor

When you position the cursor over a target, the cursor information area will show range and bearing from the vessel to the cursor position.

This measuring option gives a fast and precise measurement of distance to a target.

Range rings and bearing scale

Range rings and bearing scale are used to measure distance when a fast measurement is required. This measuring option only gives an approximate distance and speed of a target.

The range scale (A) and the distance between two adjacent range rings (B) are shown in the System Information area on the radar image.

The range scales, the related distance between the range rings and number of rings are:

Range (NM) Range rings interval (NM) Number of range rings

1/8 (200m) 1/40 (100m) 1 1/4 1/20 4 1/2 1/10 4 3/4 1/4 2

1.5 1/4 5 3 1/2 5 6 1 5 12 2 5

Maps

Maps are graphical navigation tools, composed of lines and symbols that can be added to the radar image. Maps are used to help the operator to increase the definition of the coast, restricted or dangerous areas.

For maximum number of maps, symbols and segments, refer to "Technical specifications" on page

78.

Note: The maps option must be enabled to be able to work with maps.

The maps dialog

The maps dialog lists all maps available in the unit's temporary memory and in the nonvolatile memory.

From the maps dialog you can:

• Import stored map files from the unit's internal file system or from an SD card (A)

• Select which maps that are displayed (B)

• Set a map's reference (C)

• Display the maps pop-up from where you can create new maps, edit, save, export and

delete a map (D / E)

Map references

The system includes the follow map types:

• Relative maps, which follows the position and equals the heading of own ship. All relative

map coordinates are stored as distances from own ship

• Geographic maps. The coordinates for this type of maps are stored as geographic

positions, and its elements are always drawn in the same absolute position.

When a map is saved the system automatically calculates both relative and the geographic details for all map items. When you switch reference the change is immediately committed without having to save the map.

Note: Relative maps cannot be created or imported if log or gyro is unavailable or failing.

Note: Geographic maps cannot be created or imported if EPFS (Electronic Position Fixing

System) or Gyro is unavailable or failing. A geographic map cannot be displayed if the ship is too far from the area of the map.
