1.2 Satellite Differential System
The Raystar 120 GPS Receiver utilizes a new satellite differential
correction system to improve the accuracy and integrity of the basic GPS
signals. Three separate compatible systems currently exist or are being
developed:
1. Wide Area Augmentation System (WAAS). Developed by the Federal Aviation Administration (FAA) in the USA.
2. European Geostationary Navigation Overlay System
(EGNOS). This system is being developed by a European consortium.
3. The MTSAT Satellite-Based Augmentation System (MSAS). Being
developed by the Japan Civil Aviation Bureau (JCAB) for civil aviation use.
The area coverage of the WAAS system is the furthest advanced so far
and includes the entire United States of America but also covers large
areas outside of this as shown in Figure 1-1.

Chapter 1: Overview 1-3
The combination of the WAAS, EGNOS and MSAS systems will
provide global satellite based differential GPS augmentation into the
future.
How it Works
The following description is based on WAAS, but the principles apply
equally to the EGNOS and MSAS systems.
WAAS comprises the following components:
• Ground Reference Stations across the USA
• Master Stations located at East Coast and West Coast
• Geostationary Satellites located above the equator
The Ground Reference Stations are located at known positions and
receive data continuously from GPS. The Ground Reference Stations
send their data to the Master Stations which calculate the error of the
GPS-received positions and generate correctional data.
The corrected ‘differential’ signals are then sent to the two
Geostationary Satellites which broadcast the corrected data on the
standard GPS frequency, making it available to the user’s Raystar 120
GPS Receiver.
The Raystar 120 GPS Receiver uses the correctional data transmitted by
the Geostationary Satellites to refine the GPS positional data for greater
accuracy.
WAAS is shown pictorially in Figure 1-2.

Availability of the WAAS and EGNOS
The WAAS system is presently broadcasting in North America.
The Raychart 425 Chartplotter is EGNOS compatible. However, at the
time of going to print the EGNOS was still under test.
Further information is available on the Raytheon (WAAS), and the
European Space Agency (EGNOS) websites. Links to these sites can be
found at:
http://www.raymarine.com
Broadcast Continuation and Accuracy
The continuation of the broadcast SD signals is not the responsibility of
Raymarine. The navigational accuracy of equipment using these satellite
broadcast SD signals is not guaranteed.

Trackpad and Cursor
The trackpad is used to move the cursor horizontally, vertically or
diagonally. The cursor is the cross-hair symbol (+) which is used to select
a position or item on the chart.
The longer that the edge of the trackpad is pressed, the faster the cursor
moves. The current cursor position is shown in the status bar at the top of
the screen.
The cursor is context-sensitive. Some items on the screen, such as
waypoints and chart objects have information associated with them.
When the cursor is placed over such objects, their information is
displayed in the status bar. In addition, a function bar is displayed for
certain items. For example, when the cursor is placed over a waypoint,
the waypoint data is displayed in the status bar and the waypoint options
function is displayed.
Note: During many operations the cursor cannot be moved around the
screen, eg. whilst a function bar is displayed, the cursor is used exclusively for selection. In such cases, three rapid beeps indicate invalid action.
Dedicated Keys
These keys have fixed functions. Some keys can be used in either of two
ways:
• Press: Press the key momentarily and then release it. This method is
used for most key operations.
• Press and hold: Press the key, keep it pressed for the period of time
stated (eg. 3 seconds), then release it.
When a dedicated key is pressed, one of the following occurs:
1. The associated operation is actioned, eg. change chart scale (
key).
2. A pop-up menu is displayed, providing further options.
3. A set of functions is displayed.
As a key is pressed, a single audio beep confirms the key action. If the
key-press is not valid for the current screen or mode, three rapid beeps
sound to indicate that no response is available. If required, the key beeps
can be turned off as part of your set up procedure (see Chapter 4).

Chapter 2: Getting Started
2.1 Introduction
This chapter provides information and instructions to allow you to
practice using the Raychart 425 Chartplotter. It is intended to help you
become familiar with the controls before you start using the chartplotter
for routine navigation.
Note: There is often more than one method of performing a particular
task. Normal operating procedures are detailed in Chapter 3. When you
become familiar with the system you can adapt these procedures to suit
your method of operation.
Conventions Used
Throughout this handbook, the dedicated (labelled) keys are shown in
bold capitals; for example,

Simulator
The Chartplotter display unit includes a Simulator mode, which allows
you to practice operating your chartplotter without data from a GPS
system. You will need to use the set up options to switch the display to
Simulator mode, as described in Section 2.2, Switching On/Off. You can
use it in either of two ways:
• Before the chartplotter has been installed on your vessel. In this case,
you only need to connect the Chartplotter display unit to a 12VDC
power supply, fused at 1A, connecting the red core from the power
lead to positive (+) and the black core to negative (-); see Chapter 5 for
full details.
• After the chartplotter has been installed on your vessel and while in a
marina or otherwise at anchor.

Moving Around the Chart
You will normally operate the chartplotter with the chart showing your
vessel’s current location.
In the default North-Up orientation (shown in the status box at the top of
the display), the vessel moves in relation to the screen. You will need to
reposition the chart if your vessel moves out of the area currently
displayed, or if you wish to examine or place waypoints in another area.
Alternatively, you can home the cursor onto the vessel using the
function. ‘homing’ locks the vessel to the cursor and updates the
SHIP
display such that the chart is re-drawn so as to ensure that the vessel is
always on screen, see Using
There are three ways in which you can reposition the chart:
• Use the trackpad to move the cursor to the edge of the chart; the chart
pans across. This method is useful if the area you wish to see is just off
screen.
• Automatically re-centre the vessel using the

3. To release the cursor from homed mode press the trackpad to move the
cursor away from the vessel’s current position. The status bar shows
the cursor position, range and bearing.
Changing the Chart Scale
The RANGE key changes the chart scale so that a smaller or larger area is
shown on the available cartography.
Plotter mode is available to allow you to zoom into a smaller area, even
when no chart data is available for that scale. To enable plotter mode, see
Chapter 4: Setting Up.
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).
• To move the display to another area of the chart, by zooming out to a
small scale chart, then zooming in on another position.
Each time you press the

2.5 Using Navionics Nav-Chart Cards
The chartplotter has a built-in world map that can be used for route
planning. Most areas (these are shown with chart box boundaries) are
covered at a range of approximately 512nm as shown on the Status Bar at
the top of the screen.
To use the chartplotter as a navigation aid, charts with detailed
information for the area you wish to navigate are required. The charts are
available on Navionics Nav-Chart cards, each of which can store up to 20
charts in an electronic format, depending upon its memory storage
capacity.
A Nav-Chart card provides an appropriate level of detail for a given
geographic area and scale; this data can be displayed down to a range of
1
/8 nm on the screen (height) if the data is available.

Removing a Nav-Chart card
CAUTION:
DO NOT use a metallic instrument, eg. a screwdriver or pliers, to aid
removal, as doing so can cause irreparable damage.
➤ To remove a Nav-Chart card, refer to Figure 2-7:
1. Pull out the cartridge cover at the right hand side of the unit.
2. Grip the card firmly and pull to remove it from its slot.
3. To prevent the ingress of water, replace the cartridge cover.
Note: If difficulty is experienced in removing the card, a short length of
cord can be secured between the two circular holes in the card to ease its
removal, making sure that fitting of the cartridge cover is not impeded.
Displaying the Chart Data
The new chart data will be displayed when you move the cursor into an
area covered by the new chart When a chart cartridge is inserted, the chart
is automatically redrawn.
The boundary of each chart digitized in the current card is defined by a
box or rectangle. (You can switch off the chart boundaries display as part
of the chartplotter set up described in Chapter 4).
Chapter 3: Operation 3-1
Chapter 3: Operation
3.1 Introduction
This chapter explains how to use the chart functions to navigate with the
Raychart 425.
Safety
The Raychart 425 makes it very easy to mark a waypoint and travel
towards it. However, always check first that the route is safe. If using the
chartplotter in combination with an autopilot connected via NMEA, the
autopilot will normally prompt for confirmation before it steers the vessel
towards the waypoint.
If a route has been entered using a less detailed chart, zoom in for more
detail to check for hazards, such as small shoals, that may not be shown
on the less detailed charts.
Note: Until you are familiar with interpreting the chart display, you
should take every opportunity to compare the displayed objects with visual targets, such as buoys and coastal structures. You should practice
harbour and coastal navigation during daylight and in clear weather
conditions. The equipment should not be used as a substitute for good
navigational practice.
3.2 Working with Waypoints
Introduction
The Raychart 425 enables up to 500 waypoints to be placed. A waypoint
is a position entered on a chart as a reference or destination point. All
waypoints placed on the chartplotter are stored in a waypoint database list
which includes symbol, position, bearing, range, date and time.
All waypoints in the database are displayed on screen, unless the
WAYPOINTS
Chapter 4. A waypoint can be selected, either on-screen or from the list,
for editing.
The waypoint is usually placed at the cursor position and can be part of a
route; A waypoint can also be placed at the vessel’s current position.
Waypoints can be placed before the chartplotter is installed on your
vessel.
When a new waypoint is placed, it is displayed using either the default
symbol of a cross or an alternative symbol available from the Chart Set
is set to OFF in the Chart Set Up menu, as described in
SHOW
3-2 Raychart 425 Chartplotter
Up menu, as described in Chapter 4. The waypoint is added to the
waypoint list and named with the next available number. The edit
functions can be used to change the symbol and name. When the cursor is
positioned over a waypoint, the waypoint bearing and range are
displayed.
Waypoints can also be transferred between the chartplotter, other NMEA
connected instruments or a PC, using the Waypoint Transfer functions.
This section explains how to perform the following tasks using the
on-screen cursor and the waypoint list:
• Placing a Waypoint
• Selecting a Waypoint
• Displaying Waypoint data
• Editing a Waypoint (symbol, name & position)
• Erasing a Waypoint
• Moving a Waypoint
Placing a Waypoint
Note: It is not possible to place multiple waypoints at the same position.
