INTENDED USE

The display units detailed in this handbook may form part of navigational radar systems intended for light marine use. These displays and radar systems are only an aid to navigation.

SAFETY NOTICES

This radar equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular:

1. HIGH VOLTAGE. The LCD display unit and scanner unit contain high voltages. Adjustments require specialized service procedures and tools only available to qualified service technicians – there are no user serviceable parts or adjustments. The operator should never remove the display unit cover or attempt to service the equipment.

2. ELECTROMAGNETIC ENERGY. The radar scanner transmits electromagnetic energy. It is important that the radar is turned off whenever personnel are required to come close to the scanner to perform work on the scanner assembly or associated equipment.

It is recommended that the radar scanner is mounted out of range of personnel (above head height).

Avoid looking directly at the antenna as your eyes are the most sensitive part of the body to electromagnetic energy.

When properly installed and operated, the use of this radar will conform to the requirements of ANSI/IEEE C95.1-1992 Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3Hz to 300 GHz and NRPB, Board Statement on Restrictions on Human Exposure to Static and Time Varying Electromagnetic Fields and Radiation. Doc NRPB, N0. 5 (1993).

4. NAVIGATION AID. This unit is only an aid to navigation. Its accuracy can be affected by many factors, including equipment failure or defects, environmental conditions, and improper handling or use. It is the user’s responsibility to exercise common prudence and navigational judgements. This radar unit should not be relied upon as a substitute for such prudence and judgement.

Heading and Position Data

Full functionality of the radar/chartplotter is achieved when it is part of an integrated system with other equipment (in addition to another connected via SeaTalk or NMEA 0183. Data from this equipment including position and heading is shown on the display and is used in calculations.

Details on connecting other equipment are given in Chapter 8.

Providing Heading Data for Radar/Chart Overlay and MARPA

The performance of MARPA and Radar/Chart Overlay is dependent on the quality of your heading sensor. It is important that both the heading sensor and the radar scanner (bearing alignment) are correctly calibrated. Refer to the appropriate heading sensor and radar scanner handbooks for calibration details. The better the accuracy of your heading data, the better the performance of MARPA and Radar/Chart Overlay.

A gyro compass provides the best performance in all conditions. Alternatively you could use a fluxgate compass with rate gyro stabilization. MARPA requires heading data to be frequently updated (we recommend a data output rate of greater than 8 Hz); heading data must therefore be provided on NMEA. In multiple-display systems, heading must be connected, via NMEA, to each display that will be used for MARPA.

unit)

Data

Heading and Position

We recommend the Raymarine Rate Gyro Compass system. Good results are also obtained with a Raymarine autopilot system incorporating a 150G or 400G Course Computer with internal rate gyro.

Other heading sensors connected on NMEA may provide satisfactory results in reasonable sea states. However, in unsettled conditions a rate gyro compass is advisable.

Contact Raymarine Customer Services or your authorized Raymarine dealer for additional information. For specific configuration details with the Raymarine course computer refer to Appendix E. If you are using a suitable third party heading sensor, refer to its documentation for installation and calibration details.

The Pathfinder Radar

1.2 The Pathfinder Radar PLUS Display

When a scanner is connected and the radar is in Transmit mode, the radar picture provides a map-like representation of the area in which the radar is operating. Typically, your ship’s position is at the centre of the display, and its dead ahead bearing is indicated by a vertical heading line, known as the Ship’s Heading Marker (SHM).

The radar picture can be viewed with a variety of fixed or customised range scales. The colour of the radar returns (echoes) indicates their intensity: the strongest returns are shown in yellow and the weaker are shown in shades of blue. A status bar at the top of the radar image displays range, current heading and mode indicators for the various options you can set. An example radar picture is shown on the next page, with example radar returns (echoes) and default Pathfinder Radar information. The Status Bar is also illustrated.

The radar display can show additional information, depending on your currently selected options, set up selections and the data available from other equipment. The example displays on the following pages show some of these features.

hsb

PLUS Series Color LCD Display

Functions are available to control the display as follows:

• Zoom the Display

• Offset your vessel from the centre of the radar picture

Operation of these functions is described in Chapter 2.

Pathfinder Radar PLUS Display Options

In addition to the display set up options previously described, radar set up options allow you to customise the radar image by selecting how radar marks and Electronic Bearing Line (EBL) data are displayed. You can also specify timed transmit mode and custom range scales.

The Screen Presentation Options, described in Chapter 2 allow you to switch range rings on/off and waypoint display on/off.

1.3 The Chartplotter Display

The

hsb

(PLUS) series LCD Display can include a Chartplotter. The chartplotter includes a small-scale world map and detailed navigation information is displayed when a cartographic chart card is installed. The details displayed depend on the chart zoom level selected. A plotter mode is provided to enable route plotting and tracking at large scales even when a chart card is not installed, or when the chart is zoomed beyond the available cartographic detail. A typical chartplotter screen is shown in Figure 1-3.

The chartplotter uses position information from a GPS, DGPS, WAAS or Loran-C instrument. Once the position fix has been established, your vessel’s position, if on screen, is shown as a boat shape pointing in the direction of the current heading (or COG if heading data is not available). If no heading or COG data is available, the vessel is shown as a circle.

The chartplotter screen includes a status bar that displays chart scale, with either cursor position, range and bearing or, when the cursor is homed to the vessel (by pressing

FIND SHIP), vessel position, Speed Over Ground (SOG),

Course Over Ground (COG) and fix type (VES POS, DIF FIX or SD FIX). The status bar also indicates if radar/chart overlay is switched on.

Any waypoints you have placed are displayed (unless you turned them off in Chart Set Up as described in Chapter 7) and the current route is shown. Information can be viewed on-screen by positioning the cursor over a waypoint, current route or chart object. The chartplotter screen can also show additional information, depending on your currently selected options, set up selections and data available from other equipment.

The Chartplotter

Display

An example chart display, in its default configuration, with a chart card installed, is shown in the following illustration.

Several functions are available to control the display as follows:

• Zoom in/out and Pan the Display

• Offset the Chart or Center the Chart around the Vessel

• Overlay Radar Targets onto the Chart Display

• Synchronize the Chart and Radar (if radar data is available)

Operation of these functions is described in Chapter 2.

mode is radar. Once you have used the display unit it powers-up in the last used mode. The following sections describe the power-up sequence in radar and chart modes, how to adjust the lighting and how to select simulator mode.

Radar Mode

This section explains how to switch the radar display and scanner on and off, and how to switch the scanner between Transmit, Standby and Scanner Off mode.

You normally operate your radar in transmit mode, but you can use the display unit without the scanner operating as follows:

Standby mode: You should use this mode when you are not operating the radar for short time periods. The scanner does not transmit and the antenna does not rotate, so the radar uses less power. However, the scanner remains powered so when you return to transmit mode, the magnetron does not need to warm up.

Scanner off mode: You should use this mode when you do not require the radar, but you are using the display unit say, for chart data or data from another source. Scanner off mode removes power from the scanner.

➤ To switch the display on, press and hold the POWER key until the unit beeps.

If the unit was last used in Radar mode, the keys light up, the display shows the Pathfinder graphic, followed by the start-up information illustrated below, and the radar starts the magnetron warm-up sequence.

• The cursor is homed onto the vessel position and moves with it.

Synchronize the Radar and Chart

If you have a combined radar/chartplotter display, with chart and radar windows on and you have selected Radar/Chart Synch in Chart Set Up (Section 7.7, Chart Set Up Parameters),

FIND SHIP can be used to synchronize

Chapter 2: Getting Started & Adjusting the Display 2-21

the radar and chart images. It is recommended that you set the radar to True motion to ensure the radar and chart images remain synchronised when the vessel moves. When you press

FIND SHIP the following occur:

• The chart is redrawn so that its center position matches that of the radar dis-

play.

• The radar is redrawn to the scale and heading mode of the chart.

Note: Depending on the topology of the coastline, the radar returns may not relate to the charted shoreline, the radar image will therefore be different to the chart display. For example, a gently sloping beach with a cliff several hundred metres beyond the charted coastline, the cliff is not shown on the chart but will be displayed on the radar image.

Changing the Chart Scale

The RANGE key allows you to change the chart scale so that you can see a smaller or larger area on the screen.

Plotter mode is available to allow you to zoom into a smaller area, even when no chart data is available for that scale. Section 7.7 describes how to set plotter mode on/off.

Moving Around the

You can change the chart scale for two purposes:

• To see either more detail (of a smaller area) or a larger area (in less detail)

on the screen.

• To move the display to another area of the chart, by zooming out to a small

scale chart, then zooming in on another position centered on the cursor.

The cartographic detail available on charts varies according to the chart scale and some areas include detail at smaller scales than others. This can cause blank areas on the display when adjacent areas with different levels of detail are displayed. To reduce this affect you can use the Chart Set Up options (see Section 7.7) to set chart display detail to simple. Then, as you zoom in, charted areas are displayed but with less detail shown.

Each time you press the

series Pathfinder Radar. Additional functions, that are available on

You can use this chapter with the radar display set to simulator mode, or on the water after you have installed and set up your

hsb

series Pathfinder Plus Radar

system.

This chapter covers the following topics:

• Range control.

• Interpreting and adjusting the radar picture, including adjusting the gain, sea clutter and rain clutter, changing the targets display, and tuning the radar.

• Measuring range (distances) and bearings using Variable Range Markers (VRMs) and Electronic Bearing Lines (EBLs).

• Setting up guard zones and handling alarms.

• Using MARPA for target tracking and risk analysis.

Note: Until you are familiar with interpreting the radar display, you should take every opportunity to compare the radar’s display patterns with visual targets, such as other vessels, buoys and coastal structures. You should practice harbour and coastal navigation during daylight and in clear weather conditions.

If you have a combined radar/chartplotter, or have an

hsb

series Chartplotter as part of an integrated system, you can identify objects using either the radar/ chart overlay (see Radar/Chart Overlay on page 2-23) or the cursor echo feature: With cursor echo on (see Section 4.5 and Chapter 7) you can select an object on the radar display, the cursor is repeated on the chart display so you can check the object’s identity.

3.2 Range Control

The radar picture can be viewed at various scales. The shortest range scale gives a maximum range of to the top of the radar picture. The longest range scale gives a maximum range of between 24 and 72 nautical miles depending on your scanner.

•The short range scales provide greater detail of the radar echoes close to

your vessel, and should be used as you approach the coastline, harbour or other vessels in the area.

The Pathfinder Plus Radar display includes concentric range rings, which you can use to help you to judge distances on the radar picture. Their number and spacing are adjusted automatically if you change the range scale. They can be turned off (see Switching Radar Range Rings or Chart Grid On and Off on page 2-13).

3.3 Interpreting and Adjusting the Radar Picture

Picture

Adjusting the Radar

Interpreting and

Navigational echoes may be large, small, bright or faint, depending not only on the size of the object but also on its orientation and surface. Different objects reflect the radar signals in different ways. For example, vertical objects such as cliffs reflect signals better than sloping ones such as sandbanks.

High coastlines and mountainous coastal regions can be observed at the longest radar range. However, the first sight of land may be a mountain several miles inland from the coastline. The actual coastline may not appear on the radar until the vessel is close to the line of sight distance.

The radar indication may not be similar to your visual observation; a nearby small object may appear to be the same size as a distant large object on the radar. However, with experience the approximate size of different objects can be determined by the relative size and brightness of the echoes.

Some targets, such as buoys and small boats, can be difficult to differentiate, since they bob and toss about in the waves and do not present a consistent reflecting surface. Consequently, these echoes have a tendency to fade and brighten and, at times, to disappear momentarily. Buoys and small boats often resemble each other, but boats can usually be distinguished by their motion.

Not all radar echoes are produced by hard navigational items. Some echoes may be received from irregularities on the surface of the water, particularly at close range (sea clutter), or from rain or snow either around the vessel or in the distance. In addition, some echoes may be indirect returns to the radar scanner, providing false echoes or multiple echoes. The effects of many false echoes can be minimized, and the target presentation clarified using the controls summarized below. This section explains how to interpret the radar picture and how the controls affect the display. It provides instructions for adjusting the settings, describes the circumstances in which they should be adjusted, and how they interact with each other.

Identifying False Echo Returns

Not all echoes are direct returns to the radar antenna. Occasionally signals appear at positions where there is no actual target. These are called false echoes, and may be caused by side lobes, ghost images, indirect echoes or multiple echoes.

This section briefly describes the echo patterns that can be produced by false echoes and the likely cause. It should be noted that the radar operator, through observation, practice, and experience, can generally detect these conditions very quickly. These effects can usually be minimized using the radar controls.

Side Lobes

A small part of the RF energy from each transmitted pulse is radiated outside the single narrow beam. This produces side lobe patterns, shown in Figure 3-3.

AUTO AUTO-HARBOUR OFF OFF

ON OFF

OFF

Returns

Identifying False Echo

Side lobes have no effect on distant or small surface objects. However, the echo from a large object at short range may produce an arc on the radar screen similar to a range ring or a series of echoes forming a broken arc. Side-lobe echoes normally occur at ranges below 3nm, and can be reduced by adjusting the

SEA control.

Figure 3-4: Indirect Echoes

Multiple Echoes

Multiple echoes appear if there is a large target with a wide vertical surface at a comparatively short range. The transmitted signal will be reflected back and forth between the target and your own ship. Multiple echoes therefore appear beyond the true target’s echo on the same bearing, as shown in Figure 3-5. This is not very common.

MULTIPLE ECHOES

Multiple echoes

Figure 3-5: Multiple Echoes

D1642-1

Blind Sectors or Shadow Effect

Funnels and masts located near the antenna, may cause shadows. In shadow areas beyond the obstruction there will be a reduction of the beam intensity, although not necessarily a complete cut-off. However, there will be a blind sector if the subtended angle is more than a few degrees. There may also be multiple echoes which extend behind the obstruction. This should be avoided by careful selection of the scanner site prior to installation (Chapter 8).

Gain Control and Sea Control

The GAIN control can be set to either Auto or Manual. In Auto mode, the Pathfinder Plus radar optimizes the setting. The Harbour (default), Auto-Offshore or Manual mode. In Auto-Offshore mode, the Pathfinder Plus Radar optimizes its settings to account for the effects of sea clutter. In harbours or close proximity to land different auto settings may

be necessary to cater for the effects of land clutter. To avoid losing small targets it is therefore advisable to set the Sea control to Auto-Harbour mode. Alternatively, set both Sea and Gain to Manual mode then adjust the settings to ensure that all close small targets are visible.

The

GAIN control adjusts the level of the display of signals received from the

scanner; it is equivalent to a volume control on a radio.

Gain Control

When the GAIN control is set to Manual, you should check it every time you change the range scale.

On long range settings, the gain should be set to give a slight speckle in the background of the radar picture. Do not set the gain too low, or you may miss small or weak targets.

On shorter ranges, you may wish to reduce the gain slightly to reduce the speckle and therefore improve target definition.

Sea Clutter Control

Radar returns from waves around your vessel can clutter the centre of the radar picture (see Figure 3-7, making it difficult to detect real targets. Such sea clutter usually appears as multiple echoes on the display at short range scales,

Chapter 3: Standard Radar Operations 3-9

and the echoes are not repetitive or consistent in position. With high winds and extreme conditions, echoes from sea clutter may cause dense background clutter in the shape of an almost solid disc.

D3968-1

Figure 3-7: Sea Clutter

The SEA control reduces the gain level in the areas near your vessel, extending up to 3 to 5nm depending on the wave and sea conditions. This has the effect of reducing the sea returns to intermittent small dots, while small targets are still visible. Gain levels further from your vessel remain unchanged.

You can use the gain and Sea control to help minimize the effects of side lobes (see Identifying False Echo Returns on page 3-5).

Note: On short range scales, do not set the Sea control so high that all clutter is removed, since this could stop you seeing echoes from close targets.

Tuning the Receiver

The TUNE control is used to fine tune the receiver in the scanner for maximum target returns on the display. In Auto mode, the radar tunes itself automatically on all range scales. We recommend that you leave the

TUNE control in Auto

mode.

If you do set the

TUNE control to Manual, you will need to adjust it about 10

minutes after you have turned on the radar, since the required setting changes once the magnetron has warmed up.

You should adjust the control to obtain the maximum signal strength, as indicated in the 8-step bar above the slider. If you cannot tune the radar successfully, refer to Section 7.6 for information on the Tune Preset function.

Rain Clutter Control, using RAIN and FTC

The radar can see echoes from rain or snow. Returns from storm areas and rain squalls consist of countless small echoes that continuously change size, intensity, and position. These returns, shown in Figure 3-8sometimes appear

•The

tance from your vessel, such as that shown below.

O F F

FTC

D3967-1

Figure 3-8: Rain Clutter

When the FTC control is turned up, only the leading edge of large (rain clutter) echoes is displayed, while the effect on smaller (ship) echoes is only slight. This means that you can also use the control on shorter ranges to distinguish between two very close echoes on the same bearing, which may otherwise merge and appear as one echo.

When the

FTC control is turned up, the receiver is less sensitive, and there is a

reduction of background noise and fill-in returns from land and large targets. You should therefore turn the control down when its use is not required. Since storm cells are usually visible for long distances due to their extreme altitude, you may wish to leave them displayed so that you can observe the location of bad weather.

If you turn the

RAIN or FTC control Off (equivalent to setting the level to 0%),

the actual setting is stored, and restored when you turn the control on again.

RAIN and FTC are reset to Off at power-on.

Interference Rejection

Mutual radar interference is likely when two or more radar-equipped vessels are operating within range of each other. This usually appears as a series of small dots moving to and from the display center in a straight line or a long, sweeping curve. This type of interference is most noticeable at long ranges.

D1639-1

Target Expansion

You can make targets easier to see by expanding them. The scanner type determines the range at which target expansion is available. Target expansion overrides the normal pulse length, thereby increasing the size of the target seen on the screen. However, this is at the expense of range resolution.

Target Wakes

You can see the direction and speed with which targets are moving relative to your vessel by selecting the target wakes display option.

When wakes are switched on, the target is displayed at the brightest level and the previous positions of targets are retained at successively fainter levels on the screen. You can select long, medium or short wakes, which retain information from previous scans at a reduced video level.

You can clear existing wakes from the display by pressing the soft key. The soft key is only available when wakes are switched on; the display starts showing new wakes as soon as the old wakes have been cleared.

Note: When using VRM/EBLs, you may wish to turn off the range rings to make the VRMs clearer (see Section 2.4).

VRMs move if you change the range scale, so that the actual range you have marked is maintained. VRM/EBLs also move if you offset the centre.

When a VRM/EBL pair is active, its bearing and range are displayed in its associated data box, which can be moved, deleted or reinstated.

The bearing information is displayed as either the bearing relative to your vessel’s heading or (if heading data is available from a position fixer or compass) the actual bearing in degrees magnetic or degrees true. These are controlled by the setup parameters (see Section 7.4).

The VRM/EBL functions allow you to perform the following tasks:

Measuring Range and

sor data box: If the cursor readout is set to display range and bearing (rather than Lat/Long), you can determine the range and bearing by moving the cursor over the target and checking the cursor data box readings. You can also estimate the range to a target by reference to the range rings.

Measuring Range and Bearing to Target from Vessel

To measure the range and/or bearing of a target or point from your vessel’s position, you need to place a VRM/EBL and move it so that it crosses the target or point for which you require the bearing or range.

When you turn on a VRM/EBL, it is displayed in its last-used position.

Note: If the VRM’s last-used position is outside the radar picture at the current range setting, it is placed at its default position instead. This is one third of the range for VRM1, and two-thirds for VRM2.

Measuring Range and Bearing Between Targets (FLOAT)

You can measure the range and bearing between any two points on the radar, such as two targets, using the Pathfinder Plus Radar’s Float function. This allows you to move the origin of a VRM/EBL away from your vessel’s position and onto a target. You can then change the angle of the EBL, relative to its new origin, to obtain the bearing between two points. The radius of the VRM can also be adjusted to determine the distance between two points.

3.6 MARPA

Introduction to MARPA

The Aid) function for target tracking and risk analysis. This section gives an introduction to the Pathfinder Plus Radar MARPA system and shows you how to use the MARPA functions, you should also read Section 7.5.

MARPA improves the standard of collision avoidance by obtaining detailed information for several automatically tracked targets. MARPA provides continuous, accurate and rapid situation evaluation.

You can acquire up to ten targets, which are then automatically tracked by the MARPA system. MARPA calculates target bearing and range, true speed and course, CPA (Closest Point of Approach), and TCPA (Time to Closest Point of Approach).

Each tracked target can be displayed with a vector depicting approximate target speed (vector length) and course (vector direction). The calculated target data can also be shown on the screen. Each target is continually assessed and you are warned if one becomes dangerous or is lost.

Effective MARPA operation is dependent on accurate own ship’s heading, plus SOG and COG. The better the quality of the heading data, the better MARPA will perform. (MARPA functions without SOG and COG data but only relative vector, CPA and TCPA are shown; target course and speed cannot be calculated). For more information on heading sensors, and how to connect them to your display, refer to Heading and Position Data on page 1-9 and Appendix E.

series displays include a MARPA (Mini Automatic Radar Plotting

MARPA

SAFTEY NOTICES

MARPA can improve collision avoidance when used wisely. It is the user’s responsibility to exercise common prudence and navigational judgements.

There are conditions where acquiring a target may become difficult. These same conditions may be a factor in successfully tracking a target. Some of the conditions are:

• The target echo is weak.

• The target is very close to land, buoys or other large targets.

• The target or your own ship is making rapid manoeuvres.

• Choppy sea state conditions exist and the target is buried in excessive sea clutter or in deep swells.

3-24

hsb

PLUS Series Color LCD Display

• Choppy sea state conditions exist yielding poor stability; own ship’s heading data is very unstable.

• Inadequate heading data

Symptoms of such conditions are that acquisition is difficult and the MARPA vectors are unstable; the symbol wanders away from the target, locks onto another target or changes to a lost target symbol. If any of these

Introduction to

MARPA

conditions are present, acquisition and tracking may need to be re-initiated or, in some cases be impossible to maintain. Improving the quality of the heading data will reduce the effect of the other conditions.

Risk Assessment

Each target is monitored to see if it will be within a certain distance from your own vessel within a certain time. If so, the target is designated as dangerous and you are warned with an audible alarm in addition to a warning on the screen. The target symbol changes and flashes to indicate that it is a dangerous target. Pressing any key silences the alarm and removes the warning, but the target symbol remains dangerous.

Both the distance (Own Vessel Safe Zone) and the time (Time to Safe Zone) are selectable as described in Section 7.5.

If a target is lost, either because the MARPA software has lost contact with it, or because it has moved out of range, you are warned, again with an audible alarm and an on-screen warning. Pressing any key silences the alarm, removes the warning and removes the lost target symbol from the screen.

Target Data

All MARPA targets are stored in a MARPA database list, which shows bearing, range, course and speed of each tracked target.

For any one target a pop-up data box can be placed on the screen, this shows bearing, range, course, speed, CPA (Closest Point of Approach) and TCPA (Time to Closest Point of Approach). The target for which data is displayed is indicated by a circle around its symbol.

Each target is displayed as a symbol to indicate its status:

Target is being acquired

Target is safe

Target is dangerous.

Target is Lost

The dangerous and lost symbols are shown flashing.

Chapter 3: Standard Radar Operations 3-25

Target Vector and History

The MARPA targets can be displayed with a vector line showing where they will be at a certain time in the future, (assuming present course and speed). You can select a relative or true vector and the vector length. The vector type (RV or TV) and length are shown in the status bar.

You can also select to view the target’s history, this appears as a series of dots that are dropped by the target as it makes way. The interval between them is selectable.

A relative vector indicates the target’s motion related to your own ship’s motion. The target’s relative course and speed are calculated to produce a vector that is displayed on the target only. This mode is used for collision avoidance and threat assessment.

A true vector indicates the target’s motion over ground. In this mode true vectors for the target and your own ship are displayed. MARPA measures the direction in which the target and own ship are actually moving over the ground. The result is the vessel’s true course, the rate of motion is the vessel’s true speed. Consider this motion as if you were in a helicopter looking down watching the targets move across the water. This mode can aid navigation.

Using MARPA

Section 7.5 describes how to set the target vector and history parameters.

Repeater Displays

On an integrated software version) can access the MARPA functions, and targets are shown on the repeater display. MARPA data is also sent on NMEA allowing any other equipment, with the necessary functionality, to show the tracked targets’ data.

Radar Range Scales

MARPA target acquisition is only available at radar range scales of up to 12nm, although tracking continues at all ranges.

Note: If you change to a lower range scale, targets may be beyond the range of the scanner and will be lost. In such cases an alarm pop-up indicates the target is off-screen.

Using MARPA

The MARPA functions are accessed through the MARPA default soft key, and some options are available with the context sensitive cursor, or through the MARPA database list. Where there are two ways of performing a certain function this section describes both ways. Information on how to set up the MARPA system is in Section 7.5.

4.2 Changing the Heading Mode

The radar picture is normally shown with your vessel’s dead ahead bearing straight up, as indicated by the Ship’s Heading Marker at 0° relative bearing. This is the Head Up orientation.

If heading information is available via a SeaTalk or NMEA connection, you can choose a different heading mode. In Course Up and North Up mode you can also select relative or true motion.

Relative motion is the default for the radar display. In relative motion your own ship’s position remains fixed on the radar screen and all radar targets move relative to your own ship.

In true motion, fixed radar targets maintain a constant position on the screen, whilst your own ship moves across the radar image at the appropriate speed and heading. A map-like image is thus displayed, with all moving vessels travelling in true perspective to each other and to fixed land masses. As your ship’s position approaches the edge of the screen, the radar display is automatically reset to reveal the area ahead of your ship. You can manually reset your ship’s position at any time by pressing the

TRUE REL soft key twice.

Heading Modes

The heading modes are as follows:

True and Relative Motion

Head Up

North Up Course Up

Figure 4-1: Radar Heading Modes

• Head Up: The radar picture is displayed with the vessel’s current heading upwards. As the heading changes the picture will rotate.

• North Up: The radar picture is stabilized and displayed with north upwards. As you change heading, the ship’s heading marker moves.

• Course Up: The radar picture is stabilized and displayed with the currently selected course upwards. As you change heading, the ship’s heading marker moves. If you select a new course, the picture resets to display the new course upwards.
