Chapter 1: Introduction
1.1 Satellite Differential System
The Raystar 120 SatelliteDifferential GPSReceiver utilizesa new
satellite differential system to improve the accuracy, integrity and
availability ofthe basic GPSsignals, resulting insatellite differential
correctionsand enhanced positionalaccuracy over standardGPS
receivers. Threeseparate compatible systems currently existor are
beingdeveloped:
1. Wide AreaAugmentationSystem (WAAS).Developedby the
FederalAviationAdministration(FAA).
2. EuropeanGeostationary Navigation Overlay System
(EGNOS). Thissystem isbeing developed bya Europeancon-
sortium.
3. TheMTSATSatellite-Based Augmentation System(MSAS).
Thisis being developedby theJapan Civil AviationBureau
(JCAB) for civil aviation use.
Thearea coverageof theWAAS systemis thefurthestadvanced so
farand includestheentireUnitedStatesof Americabut also covers
largeareas outsideof thisas shown inFigure 1-1.

1-2 Raystar 120 GPS Receiver
Thecombinationof theWAAS, EGNOSandMSAS systems will
provide global satellite based differential GPSaugmentation into the
future.
How it Works
The following description is based onWAAS,but theprinciples
apply equally totheEGNOS andMSAS systems.
WAAScomprisesthefollowingcomponents:
• GroundReference Stations across theUSA
• Master Stationslocated at East Coast and WestCoast
• GeostationarySatelliteslocatedabove theequator
TheGround ReferenceStations are located atknown positionsand
receivedatacontinuouslyfromGPS.TheGroundReferenceStations
send their datato the MasterStationswhich calculatetheerrorof the
GPS-received positions and generatecorrectionaldata.
The corrected ‘differential’ signalsare thensent to the two
GeostationarySatelliteswhichbroadcast the corrected data onthe
standardGPS frequency, makingit availableto theuser’s
Raystar 120 GPSReceiver.
TheRaystar 120GPSReceiverusesthecorrectionaldatatransmitted
bythe Geostationary Satellitestorefine theGPSpositionaldata for
greater accuracy.

2.1 EMC Installation Guidelines
Althougheveryefforthasbeen takentoensurethat ourproductswill
performunderall conditions,it isimportantto understandwhat
factorscouldaffect theoperation ofthe product.
Theguidelinesgiven heredescribethe conditionsforoptimumEMC
performance,butit isrecognized thatit may notbe possible tomeet
allof these conditionsinall situations.To ensurethe bestpossible
conditionsforEMC performancewithin theconstraintsimposed by
anylocation,always ensurethemaximum separationpossible
betweendifferent itemsof electrical equipment.
For optimumEMC performance,itis recommendedthat wherever
possible:
• Raymarine equipmentand cablesconnected toit are:
• Atleast 3ft (1m)from anyequipmenttransmitting orcables
carrying radio signalse.g. VHFradios, cables and antennas.
Inthe caseofSSB radios,thedistanceshould be increasedto
7ft(2m).
• Morethan 7ft (2m) fromthepath ofa radar beam.A radar
beam can normally be assumed to spread 20degrees above
and belowthe radiating element.
• Theequipmentis suppliedfroma separatebatteryfrom thatused
forenginestart.Voltagedropsbelow10 V,andstartermotortran-
sients,can causetheequipment toreset.This willnotdamage the
equipment,but maycause the loss ofsome informationand may
change the operating mode.
• Raymarine specified cables areused. Cutting andrejoining these
cables can compromiseEMC performanceand mustbe avoided
unlessdoingso is detailed inthe installation manual.

GPS Receiver Installation
TheRaystar 120GPS Receiveris designed toreceive thesignals
emittedfrom thesatellites in adirect path.Ideally, theunitshould be
mountedhorizontallyinalocationthatisopenandclearofanymasts,
search lights, or otherstructuresthat couldblock line-of-sight
reception of signals.The heightof theGPS Receiver isnot as
importantas it’shaving aclear viewhorizonto horizonfor optimum
signalreception.Infact,thelowertheunitcan bemountedandhavea
clear view tosatellites,the better. Themore stable theunit, the easier
itis totracksatelliteslowerto thehorizon.
TheRaystar120canbemountedonapole.Alternatively,youcanuse
thesupplied surface mountkit.
Whenmounting theGPS Receiver flushto adeck surface,avoid
areas where theunit will betroddenupon orwhere it maypresent a
tripping hazard.
Whenplanningthe locationfor theunit,considerfinding a
convenientpathwayfor runningthe interconnectingcable between
theGPS Receiver andthe displayunit orto therest of anintegrated
system.Ideally thecableshould berunin amanner suchthat it is
hiddenfrom view and,if possible, be ina directpathto thepointof
connection. Itis importantto keepthecableseparated from other
shipboardcables asfar as possibleto prevent interferencepick-up.

Using a Connector Block
WhenconnectingaRaystar 120intoanexistinginstrumentsystemor
tocertain Raymarine chartplotters(eg. Raychart 630) a connector
blockcan beused to connect intotheSeaTalk bus.
IfDC poweris notalready available viaan existing SeaTalk
instrument,a connectorblockcan be used tosupplypower tothe
