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 Augment ation System (W AAS). Developed by th e Federal A viation Administration (F AA) in the USA.
2. European Geostationary Navigation Overlay System
(EGNOS). This system is being devel oped by a European consortium.
3. The MTSA T Satellite-Based Augmentation System (MSAS). Being
developed by the Japan Civil A v iation Bureau (JCAB) for civil aviation use.
The area coverage of the W AAS 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 W AAS, EGNOS and MSAS systems will
provide global satellite based different ial 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.
W AAS comprises the following components:
• Ground Reference Stations across the USA
• Master Stations located at East Coast and W est 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’ signa ls are then sent to the two
Geosta tionar y Satelli tes wh ich broadcast the corrected data on the
standard GPS frequency , making it available to the user’s R aystar 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.
W AAS is s hown pictorially in Figure 1-2.

D4903-1
1-4 Raychart 425 Chartplotter
Availability of the WAAS System in North America
The W AAS system is presently broadcasting and being tested for
aviation use. It is expected to be certified by the F AA in 2002. During this
testing and certification period, continuous service is expected, however,
brief signal outages may occur as refinements and upgrades are made to
the system. The status of W AAS and planned outages are available online at Raytheon’s website http://wwws.raytheontands.com/waas
or http://www.raymarine.com
Coverage Outside of North America
EGNOS is currently in the early testing and qualification phases and
signal outages may occur at any time. The status of EGNOS and any
planned outages are available on-line at Raytheon’s website
http://www.raymarine.com
Use of Satellite Differential is currently disabled outside of the W AAS
reception area. When EGNOS is qualified for navigational use, a
procedure will be published on our websi te which will enable EGNOS
operation. See http://www.raymarine.com
for latest information.
Accuracy and Continuation of Broadcast Coverage
The navigational accuracy of equipment using these satellite broadcast
SD signals during the testi ng and qualification phases is not guaranteed
by Raytheon Marine Company or Raytheon Corporat ion, nor is the
continuation of the broadcast SD signals the respon sibility of Raytheon
Marine Company or Raytheon Corporation.

Trackpad and Cursor
The trackpad is used to move the cursor horizontally , vertically or
diagonally . The cursor is the cross-hair symb ol (+) 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 i n 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 ass ociated with them.
When the cursor is placed over such objects, their information is
displayed in the status bar . In addition, a function bar is dis played 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.

Chapter 2: Getting Started 2-1
Chapter 2: Getting Started
2.1 Introduction
This chapter provides information and ins tructions 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: Ther e is often more than one method of perf orming a particular
task. Normal operating procedures are detailed in Chapter 3. When you
become familiar with the system you can adapt t hese procedures to suit
your method of operation.
Conventions Used
Throughout this handbook, the dedicated (labelled) keys are shown in
bold capitals; for example,
ENTER. The functions and options are shown
in normal capitals, eg.
LIGHT.
Operating procedures, which may consist of a single key-press , or a
sequence of numbered steps, are indicated by a
➤ symbol in the margin.
When textual data is displayed on screen, any unavai lable data is shown
as dashes, one per character .
Where procedures refer to Select, this im plies usin g the trackpa d to
highlight a function, then pressing the
ENTER key to action that function.
Simulator
The Chartplotter display unit includes a Simulator mode, which allows
you to practice operating your chartplotter without data from a GPS
system. Y ou will need to use the set up options to switch the display to
Simulator mode, as described in Secti on 2.2, Switching On/Off. Y ou 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 displ ay 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
Y ou 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. Y ou will need to
reposition the chart if your vessel moves o ut 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
FIND
SHIP
function. ‘homing’ locks the vessel to the cursor and updates the
display such that the chart is re-drawn so as to ensure that the vessel is
always on screen, see Using
FIND SHIP below.
There are three ways in which you can reposition the chart:
• Use the trackpad to mo ve 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
FIND SHIP function.
• Change the chart scale using the
RANGE key to zoom out and in to a
new area. This method is useful if the area you wish to see is some distance away.
Using FIND SHIP
FIND SHIP is used to re-draw the chart with the vessel normally at its
centre and the cursor homed on the vessel.
➤ T o centre the vessel:
1. From chart mode, press
ENTER; the primary function bar is displayed
(Figure 2- 4):
Figure 2-4: Primary Function Bar
2. Select FIND SHIP; the following actions are performed:
• The chart is re-drawn with the vessel’s position in th e centre.
• The cursor is homed onto the vessel position and moves with it.
• When the vessel moves near the edge of the chart window, the chart
is redrawn with the vessel at the centre and the cursor homed on the
vessel.
• Whilst homed, the status bar indicates vessel posi tion,
SOG and
COG.
Chapter 2: Getting Started 2-7
• If Screen Amplifier is enabled, the vessel is positioned so as to
increase screen forward visibility, see Chapter 4 : Setting Up.
3. T o 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.
Y ou can change the chart scale for two purposes:
• T o see either more detail (of a smaller area) or a larger area (in less
detail).
• T o move the display to another area of the chart, by zooming ou t to a
small scale chart, then zooming in on another posi tion.
Each time you press the
RANGE key , the chart scale changes to the next
available setting. The Status Bar at the top of the screen indicates the
distance, from top to bottom of the display , in nautical miles (Figure 2-5).
Figure 2-5: Status Bar Indication
➤ For rapid scale change, press and hold the required arrow on the RANGE
key .
The distance indicator at the left-hand end of the status bar is updated
whenever you change the chart scale.
➤ T o zoom in to a more d etailed ch art:
1. Use the trackpad to position the cursor in t he area you wish to see in
more detail and press the bottom of the
RANGE key to zoom in.
The section of the chart around the cursor is enlarged to fill the screen
with the chart showing more detail. The cursor is now positioned in
the centre of the screen.
The distance indicated at the top left of the screen is updated.

2. If further chart enlargement is available using the current chart card
you can press the bottom of the
RANGE key to zoom in again, reposi-
tioning the cursor first if required.
An area of further chart detail is indicated by a box around the area as
shown in Figure 2-6.
Figure 2-6: Chart Detail Boundaries
3. If no further chart detail is available then, when the bottom of the
RANGE key is pressed, the result depends up on whether Plotter Mode
is on or off:
• If Plotter Mode is Off, the chart scale remains unchang ed, indicat-
ing that the greatest detail is displayed.
• If Plotter Mode is On, the scale is decreased but, as there is no fur-
ther detail, the vessel, waypoints, routes and t racklines are displayed without cartography .
The chart information is restored when you return to a chart scale for
which the information is available.
➤ T o zoom out to a less detailed chart, press the top of the RANGE key as
many times as required.

2.5 Using Navionics Nav-Chart Cards
The chartplotter has a built-in world map that can be used for rout e
planning. Most areas (these are shown with chart box boundaries) are
covered at a range of approximately 512nm as shown on the S tatus Bar at
the top o f the scr een.
T o 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 memo ry storage
capacity.
A Nav-Chart card provides an appropriate level of detail f or 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.
T o obtain Navionics Nav-Chart cards, contact your local dealer or v isit

Chapter 3: Operation 3-1
Chapter 3: Operation
3.1 Introduction
This chapter explains how to use the chart functions to navigate wi th 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
chartpl otter in c ombinat ion with an autopil ot connec ted via NM EA, the
autopilot will normally prompt for confirmation before it steers the vessel
towards the waypo int.
If a route has been entered using a less detailed chart, zo om in for more
detail to check for hazards, such as small shoals, that may not be show n
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 coas tal structures. You should practice
harbour and coastal navigat ion during daylight and in clear weather
conditions. The equipment sh ould 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, rang e, date and time.
All waypoints in the database are displayed on screen, unl ess the
SHOW
WAYPOINTS
is set to OFF in the Chart Set Up menu, as described in
Chapter 4. A waypoint can be selected, either on-screen or from the list,
for editing.
The waypoint is usually placed at the cursor posi tion and can be part of a
route; A waypoint can also be placed at the vessel’s current position.
W aypoints can be placed before the chartplotter is installe d 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
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 bearin g and range are
displayed.
W aypoints can also be transferred between the chartplotter, other NMEA
connected instruments or a PC, usi ng the W aypoint T ransfer functions.
This section explains how to perform the fol lowing tasks using the
on-screen cursor and the waypoint list:
• Placing a W aypoint
• Selecting a W aypoint
• Displaying W aypoi nt data
• Editing a W aypoint (symbo l, name & position)
• Erasing a W aypoint
• Moving a W aypoint
Placing a Waypoint
Note: It is not possible to place multiple waypoints at the same position.
➤ T o place a new waypoint:
1. From chart mode, press
ENTER; the primary function bar is displayed
(Figure 3-1):
Figure 3-1: Primary Function Bar
2. Using trackpad left/right, select WAYPOINTS (Figure 3-2).
