Chapter 1: Introduction
1.1 Satellite Differential System
The Raystar 120 Satellite Differential GPS Receiver utilizes a new
satellite differential system to improve the accuracy, integrity and
availability of the basic GPS signals, resulting in satellite differential
corrections and enhanced positional accuracy over standard GPS
receivers. Three separate compatible systems currently exist or are
beingdeveloped:
1. Wide AreaAugmentationSystem (WAAS).Developed by the
FederalAviationAdministration(FAA).
2. European Geostationary Navigation Overlay System
(EGNOS). This system is being developed by a European con-
sortium.
3. The MTSAT Satellite-Based Augmentation System (MSAS).
This is 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 asshown in Figure 1-1 .

1-2 Raystar 120 GPS Receiver
Thecombinationof theWAAS, EGNOSandMSAS systemswill
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 theUSA
• Master Stations located at East Coast and West Coast
• Geostationary Satelliteslocated above the equator
The Ground Reference Stations are located at known positions and
receivedatacontinuouslyfromGPS.TheGroundReferenceStations
send their data to the Master Stationswhich calculate the errorof the
GPS-received positions and generate correctional data.
The corrected ‘differential’ signals are then sent to the two
GeostationarySatelliteswhich broadcast the corrected data on the
standard GPS frequency, making it available to the user’s
Raystar 120 GPS Receiver.
TheRaystar 120GPSReceiverusesthecorrectionaldatatransmitted
by the Geostationary Satellites torefine the GPSpositional data for
greater accuracy.

Accuracy and Continuation of Broadcast Coverage
The navigational accuracy of equipment using these satellite
broadcastSDsignalsduringthetestingandqualificationphasesisnot
guaranteed byRaymarine Limited,nor is the continuation of the
broadcast SD signals the responsibility of Raymarine Limited or
RaytheonCorporation.
Note:On some earlier equipments which were designed before
WAAS and similar systems were available (eg. Raychart630), a Sat-
ellite Differential fix (SD-FIX) will be reported as D-FIX.
In such cases a Satellite Differential fix will still be acquired and the
enhanced navigational accuracy of the Satellite Differential system
will still be utilized.

2.1 EMC Installation Guidelines
Althoughevery effort has been takento ensure that ourproducts will
perform under all conditions, it is important to understand what
factors could affect the operation of the product.
Theguidelinesgiven heredescribe the conditionsforoptimumEMC
performance, but it is recognized that it may not be possible to meet
all of these conditions in all situations. To ensure the bestpossible
conditions for EMC performance within the constraintsimposed by
anylocation,always ensurethe maximum separationpossible
between different items of electrical equipment.
For optimumEMC performance, it is recommended that wherever
possible:
• Raymarine equipment and cables connected to it are:
• Atleast 3ft (1m)from anyequipment transmitting orcables
carrying radio signals e.g. VHF radios, cables and antennas.
In the case ofSSB radios, the distance should be increased to
7ft(2m).
• More than 7 ft (2 m) from the path of a radar beam.A radar
beam can normally be assumed to spread 20 degrees above
and below the radiating element.
• The equipmentis suppliedfrom a separate battery from thatused
forenginestart.Voltagedropsbelow10 V,andstartermotortran-
sients,can causetheequipment toreset.This willnotdamage the
equipment, but may cause the loss of some information and may
change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these
cables can compromise EMC performance and must be avoided
unless doing so is detailed in the installation manual.

Raymarine cannot be responsible for incorrect operation due to
incorrect unit specification. Always state which model you have
when making any communication with Raymarine or a registered
serviceagent.
GPS Receiver Installation
The Raystar 120 GPS Receiver is designed to receive the signals
emitted from the satellites in a direct path. Ideally, the unit should be
mountedhorizontallyinalocationthatisopenandclearofanymasts,
search lights, or other structures that could block line-of-sight
reception of signals. The height of the GPS Receiver is not as
important as it’s having a clear view horizon to horizon for optimum
signalreception.Infact,thelowertheunitcan bemountedandhavea
clear view to satellites, the better. The more stable the unit, the easier
itis totracksatelliteslowerto thehorizon.
TheRaystar120canbemountedonapole.Alternatively,youcanuse
thesupplied surface mountkit.
When mounting the GPS Receiver flush to a deck surface, avoid
areas where the unit will be trodden upon or where it may present a
tripping hazard.
Whenplanningthe locationfor theunit,consider finding a
convenient pathway for running the interconnecting cable between
the GPS Receiver andthe display unit orto the rest of anintegrated
system. Ideally the cableshould be run in a manner such that it is
hidden fromview and, if possible, be in a direct path to the pointof
connection. It is important to keep the cable separated from other
shipboard cables as far aspossible to prevent interference pick-up.
Note:Mounting on themast ofa sailboat is not recommended.

Using a Connector Block
WhenconnectingaRaystar 120intoanexistinginstrumentsystemor
to certain Raymarinechartplotters (eg. Raychart 630) a connector
block can be used to connect into the SeaTalk bus.
If DC power is not already available via an existing SeaTalk
instrument, a connector block can be used to supply powerto the
SeaTalk bus for this and other applications.
Figure 2-5 shows how the connector block is used to makethe
interconnections between the RayStar 120, the SeaTalk bus and, if
required,an external DC power supply.
