3.11 Electronic Bearing Line (EBL) and
Variable Range Marker (VRM)
3.11.1 Electronic Bearing Line (EBL) and Variable
range marker (VRM)
The electronic bearing line (EBL) and the variable range marker (VRM) are the essential tools for
measuring bearings and ranges.
This equipment is equipped with two sets each for EBL (EBL1/EBL2) and VRM (VRM1/VRM2).
An intersecting point mark is displayed at the intersecting point between EBL and VRM.
By setting an intersecting point at any location, the bearing and range from the own ship’s position to
the location can be measured.
Two sets of EBL and VRM can be operated independently.
The first EBL and VRM are displayed in Long dashed line and the second EBL and VRM are displayed
in Short dashed line.

Note
When using ECDIS in AUTO mode, if there is no object under the cursor, the chart position at the
cursor will move to the center of the screen according to "3.12.1". When the ship is under vibration
and rough sea conditions, the center of the chart will be moved to an unintended position by
inadvertent left-click operation. Confirm the cursor type on the object is changed to other types
before left-click operation for AUTO mode operation.

Range and Bearing
Measurement Methods
4.1 List of Measuring Tools
This equipment is equipped with the following measuring tools to measure the range and bearing.
Measuring tool Function Related section
Cross-Hair Cursor
(Cursor)
Used to measure the range and bearing from
the own ship’s position.
4.3 Using the Cross-hair
Cursor
Range Rings Displays concentric circles having CCRP
(Consistent Common Reference Point) as the
center at constant intervals in order to be used
as guidance for measuring the range.
4.4 Using the Range Rings
Electronic Bearing
Lines (EBL1/EBL2)
Displays a straight line that specifies an
arbitrary bearing in order to measure the
bearing from own ship.
The MFD is equipped with two electronic
bearing lines (EBL1 and EBL2).
4.5 Using the Electronic
Bearing Line (EBL) and
Variable Range Marker
(VRM)
Variable Range
Markers
(VRM1/VRM2)
Displays a circle that specifies an arbitrary
range in order to measure the range from own
ship.
The MFD is equipped with two variable range
markers (VRM1 and VRM2).
Parallel Index Lines
(PI)
Displays a group of straight lines at equal
intervals in order to be used for complex
measurement and guidance for route.
4.6 sing Parallel Index
Lines (PI)
EBL Maneuver Displays a predictable track when own ship is
turned in order to be used as guidance for
maneuvering.
4.7 Using the EBL
Maneuver
Node Fixed
EBL/VRM
Connects the own ship’s position and the
specified fixed position with EBL and VRM
markers.
Since the connection is maintained even if own
ship advances, the bearing and range of own
ship against the fixed position is always
available.
4.8 Connecting Own Ship
and the Specified Fixed
Position with EBL and the
VRM Marker (Node Fixed
EBL/VRM Function)
Manual position fix
(LOPs)
Measures the own ship’s position with LOP
(Line Of Position) and plots it on the chart. The
own ship’s position can be jumped to the
plotted position.
4.9 Measuring the Own
Ship’s Position Manually
(LOPs Fixing Function of
Manual position fix)
Manual position fix
(Position Offset)
Enables offsetting the own ship’s position with
manual operation.
4.10 Offsetting the Own
Ship’s Position Manually
(Position Offset Function of
Manual position fix)
Section 4 Range and Bearing Measurement Methods 4-2
4.2 Target Position
The radar transmits the pulse-modulated radio waves. The transmitted waves are received in the
target after being reflected (echoed). On the screen, the waves spread in the pulse width range
direction based on the target position as the front edge.
When measuring a target or setting a mark/line on the target, place the cursor on the front edge of the
echo.

4.3 Using the Cross-hair Cursor
When moving the cursor into a window, it changes to a cross-hair cursor. With the cross-hair cursor,
the bearing and position of a target can be measured.
The information that is measured by the cursor is displayed in the cursor readout information area.
4.3.1 Cursor readout information area display
position
The display method of the cursor readout information area varies between RADAR and ECDIS.
4.3.1.1 RADAR
The information can be displayed by either of the following methods.
[Placing the cursor inside of PPI]
When the cursor is placed inside of PPI, the cursor information on the position at which the cursor is
placed is displayed in the bottom right corner of the screen.
[Clicking on the cursor information display button at the bottom right corner of the screen]
When the cursor information display button on the bottom right corner of the screen is clicked on, the
"Cursor readout" dialog is displayed.

Memo
A measurement line can be set across the reference line. (When a measurement line is set across
the reference line by rotating the dial in the minus direction, the measured bearing data changes
as 0°→359.9°.)

Node Fixed EBL-VRM is the function that connects the own ship with the specified fixed position with
the EBL and VRM markers.
Since this EBL/VRM connection is maintained even if the own ship travels, it is possible to always

On the selected fixed position, the bearing and distance of the own ship against the fixed position are
displayed.

between the 2nd LOP and TPL becomes the own ship’s position based on the both-side
positioning method.
• When [HDG/STW] is set to ON, TPL of the same angle as that of the 1st LOP and same
time as that of 2nd LOP is created based on the position determined by adding the
HDG/STW vector and the Set/Drift vector.
• When [COG/SOG] is ON, TPL is created by using COG/SOG.

The intersection between LOP and TPL can also be used as the Plotted Position.
1 Select [Set plotted position] from the [Plot] button while an intersection is created from
the 2nd LOP and 1st TPL.
The "Select LOP or TPL" dialog is displayed.
2 Select the 2nd LOP and 1st TPL and click on the [OK] button.
A Plotted Position is set at the intersection of the 2

9 Click on the [Set] button by creating the 2nd L O P.
TPL is automatically drawn by determining the traveling distance from the time difference from
the 2nd LOP to the observation time and the bearing and speed of the ship.
Two TPLs are created, creating a triangle of error.

methods
Bearing and Distance
Perform position fixing from one target with one Bearing and one Distance.
Distance
Perform position fixing from the distance intersecting point from 2 to 3 targets.
The intersection becomes the own ship’s position.
However, when multiple intersections are created, the one
closest to the own ship’s position among those that are
displayed in the own ship information area is used as the
own ship’s position. In this case, the own ship’s position is
outside of the sensor detection range, the position closest
from the bearing starting point is used as the own ship’s
position.
The intersection becomes the own ship’s

Manually (Position Offset Function of
Manual position fix)
Do not use the offset function during the voyage.
If the function is used while an offset value is input in the own ship’s position
(different from the actual position), an accident may occur.
When an offset value is input, the [Offset] badge is displayed in the position
display section of Own Ship Information. Check if the own ship is off course
with this position display section. The "Position Shift" message is also
displayed in the message area.
