Chapter 1: Overview
1.1 Introduction
ThishandbookdescribestheRaychart 425Chartplotter andits
associatedRaystar 120 GPS Receiver.The Raystar 120utilizesSatellite
Differential (SD) signals for enhanced navigational accuracy over
conventional shorebased differential GPS systems(dGPS).
TheRaychart425 Chartplotteriswaterproofandcanbeinstalledeither
aboveorbelowdeck. The equipment comprises:
•6 in LCD display with Chart holder compartment for a Navionics®
Nav-Chart electronic chart card
•Raystar 120 GPS Receiver
The Raychart 425Chartplotter can output GPSand Waypoint data to
operate withotherequipment,eg. an autopilotorrepeaterinstrument
connected via the NMEA0183 interface1.
How this Handbook is Organized
Thehandbookis organized asfollows:
Chapter1: Overview(this chapter) provides anoverview of the features
andfunctionsofthe Raychart 425andassociatedRaystar 120. Please
read this chapter to familiarize yourself with the Chartplotter and
Satellite Differential system.
Chapter2: GettingStartedprovidesanoverviewofthecontrolsandhow
tostart usingthechartplotter.
Chapter3: Operationprovidesdetailed operatingproceduresforthe
main chartplotterfunctions-plottingwaypointsand routes,navigation
functions, Track handling, Port andTide information, ManOverboard
andAlarmfunctions.
Chapter4: Setting Upprovides instructionsforsetting upthe
chartplotter systemandchartingpreferences.
Chapter 5: Installationprovidesplanning considerationsanddetailed
instructions for installing the Chartplotter and GPS Receiver on your
vessel.
Chapter6: Maintenance&FaultFindingprovidesinformationonuser
maintenance and what to do if you experience problems.

Appendix Adetails the Technical Specification for the Chartplotter.
Appendix Bdetails the Technical Specification for the GPS Receiver.
Appendix Cdefines the NMEAdata received/transmittedby the
Chartplotter.
Appendix Dprovides a list ofabbreviationsused in this handbook.
Installation Templates forthe Raychart 425anditsassociated
Raystar 120 GPS Receiverare included at theendof this handbook.
1.2 Satellite Differential System
The Raystar 120 GPS Receiverutilizes anew satellite differential
correctionsystemtoimprovetheaccuracyandintegrityofthebasicGPS
signals. Three separate compatible systems currently exist or are being
developed:
1. Wide Area Augmentation System (WAAS). Developed by the Fed-
eral Aviation Administration (FAA) in the USA.
2. European Geostationary Navigation Overlay System
(EGNOS). This system is beingdeveloped by aEuropean consor-
tium.
3. TheMTSATSatellite-Based Augmentation System (MSAS).Being
developed by the Japan Civil AviationBureau (JCAB) forcivilavia-
tionuse.
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 thisas shown in Figure 1-1.
