    EMC Installation & Service Guidelines
    IMPORTANT NOTE
    All JRC equipment and accessories are designed to the highest industry
    standards for use in a marine environment. Their design and manufacture
    conforms to the appropriate Electro Magnetic Compatibility (EMC) standards,
    but good installation is required to ensure that performance is not compromised.
    Although every effort has been taken to ensure that the equipment will perform
    under all conditions, it is important to understand what factors could affect
    operation of the product. Complete installation instructions are provided in
    SECTION 2 of this manual. Some preliminary suggestions are made below.

    Installation
    To avoid the risk of operating problems, all JRC equipment and cables
    connected to it should be:
    • At least 1m (3 feet) from any equipment transmitting or cables carrying radio
    signals e.g. VHF radios, cables and antennas. In the case of SSB radios the
    distance should be increased to 2m (7 ft).
    • More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally assume to spread 20 degrees above and below the radiating element.
    • The equipment should be supplied from a different battery than the one used
    for engine start. Voltage drops below 10.2V in the power supply to our
    products can cause the equipment to reset. This will not damage the
    equipment, but will cause some loss of information and this can also change the
    operating mode.
    • Genuine JRC Cables should be used at all times. Cutting and rejoining these
    cables can compromise EMC performance and should therefore be avoided
    unless doing so is suggested in the installation manual.

    Check Before Going to Sea
    • Always check the installation before going to sea to make sure that it is not
    affected by radio transmissions, engine starting, low battery voltage, or other
    problems.
    • In some, installations, it may not be possible to prevent the equipment from
    being affected by external influences. In general this will not damage the
    equipment but it can lead to it resetting, or momentarily may result in faulty
    operation. This can then be avoided by turning off the RADAR 1800 prior to
    starting the boat engines for instance.

    Servicing and Safety
    • JRC equipment should be serviced only by authorized JRC service engineers.
    They will ensure that service procedures and replacement parts used will not
    affect performance. There are no user serviceable parts in any JRC product.
    • Some products generate high voltages, and so never handle the cables/connectors when power is being supplied to the equipment.
    • Always report any EMC related problem to your nearest JRC dealer. We will
    use any such information to improve our quality standards.

    Suppression Ferrites
    The following illustration shows the range of suppression ferrites fitted to
    JRC equipment.

    Notes for Suppression Ferrite Installation
    Connections to other equipment
    If your JRC equipment is going to be connected to other equipment using a
    cable not supplied by JRC, a suppression ferrite MUST always be fitted to the
    cable close to the JRC unit.

    Introduction

    SECTION 1

    Congratulations on selecting the JRC RADAR 1800 Color LCD system to
    assist your navigation.
    Whether you purchased this radar because of its compactness, power
    economy, ease of installation, or long term reliability, one thing is certain;the
    moment you turn on your RADAR 1800 Display you will know that you are
    seeing a revolutionary new concept in Radar technology.
    You are the proud owner of a radar system unmatched in the marine
    recreational industry.
    Radar signals are shown on a color LCD display with excellent graphic clarity
    and detail.
    A single glance at your Display will give you a complete and accurate 360˚
    radar picture of other vessels, buoys and land surrounding your vessel.
    By connecting with JRC’s GPS/DGPS sensor, the LCD Display allows you
    to continuously display latitude, longitude, scale division and track line of the
    vessel in color.
    Since the color of the vessel track line can be displayed in any color and
    deleted when required, it can be checked at a glance.
    In addition to track line, waypoints and transit point(convenient for marking
    dangerous location, shoals and fishing spots) can be stored and diplayed in color.
    The distance and bearing from the ever-changing current position to a
    waypoint is displayed automatically.
    Since displayed sea areas can be magnified, reduced or moved as desired, it
    can be used for a number of application.

    are mounted to provide easy to operate for everyone.

    Scan Correlation Feature
    The Scan Correlation signal processing function, normally only available in
    larger commercial radars, is included to provide an enhanced presentation of
    targets especially in high sea return conditions (false random targets caused by
    radar signals bouncing back from waves).

    Automatic STC Feature
    In addition to manual STC adjustment, an Automatic STC setting is also
    available to help adjust out annoying sea return targets.

    Inter Switch Feature
    With the optional Inter Switch Kit (NQE-1200), the antenna can be
    controlled by either one of the two display units installed at the cabin fly bridge,
    etc. (No simultaneous control by the two units)

    Connectable with the JRC GPS Compass
    By connecting with the JLR-10 JRC GPS Compass, you can select the
    heading mode between Head-Up, North-Up, and Course-Up.

    Various Navigation Screen Feature
    By connecting an optional GPS or DGPS sensor, such information as the
    position or course of your ship can be displayed on the screen.
    By registering WAYPOINT and ROUTE PLAN, it is also possible to display
    such important information as the distance or bearing to/of a WAYPOINT that
    ensures safe and economical navigation.
    This information can be displayed in the chart plot style, in the intuitive
    illustration style, or in the numerical style depending on your selection.

    Installation Procedure
    Installation

    CAUTION
    Insluate the GPS/DGPS sensor case from ground.
    Without insulation, a considerable amount of
    current frow from ground to this equipment.
    A considerable amount of current may cause
    equipment damage.

    When twisting on the receiver be careful not to damage the cable.

    Avoid thread damage

    Section 2 Installation

    The aluminum bottom of the GPS112/DGPS212 are designed so that it can
    be installed on the navigation antenna mount unit or on an extension mast
    conforming to 1” x 14 NPT standards. The aluminum casing is negative earth, so
    a plastic mounting unit should be used to prevent any corrosive activity from
    developing. The bottom of the receiver is provided with a slot to allow the
    receiver cable to be pulled out to the side. This eliminates the need of pulling the
    cable through the center of an extension mast.

    Grip and turn from the base

    Figure 2-5 Installation

    When the cable is pulled through the
    center of the extension mast, it is
    recommended that RTV silicon sealant be
    used to seal off the cable slot on the
    bottom of the receiver to protect it from
    The Wrap or
    the environment. When the cable is pulled Seal with
    Tape Cable
    RTV
    out through the slot, secure it in position
    to protect it against damage due to
    vibration. Then seal the slot on the receiver

    Connecting DC Power
    WARNING
    Do not touch the ground terminal and vessel ground
    on the display unit at the same time without the
    ground terminal earthed. Otherwise, you may suffer
    an electric shock.

    CAUTION

    Your unit is intended for use on vessels with 12 VDC power systems and it
    can operate as long as the DC supply is maintained between 10.2 and 16.0 VDC.
    The supplied 6.5 foot power cable assembly should reach the source of DC
    power.

    Section 2 Installation

    RED to the positive.
    BLACK to the negative.
    Do not mistake the colors, as doing so will cause a
    malfunction.

    ➔ On larger boats, route the power leads to the ship’s DC power distribution
    panel. Connect to 10 amp or 10 amp (maximum) circuit breaker, as the unit is
    fused at 10 amps.
    ➔ On smaller vessels connect the power leads directly to the main battery
    isolation switch or breaker.
    Avoid grouping the unit’s power connections with radar, radio, or Loran-C
    power leads on the same circuit breaker. Separate the wiring as much as possible
    from other devices to prevent electrical noise interference.
    Although the unit’s power consumption is approx. 50 watts, if you need to
    extend the power cable leads by more than 10 feet, increase the wire size of the
    leads accordingly to minimize line losses. For runs of 20-35 feet, #10 AWG is
    recommended.
    ➔ Connect the RED wire to the positive (+) source terminal as shown in Figure
    2-8.
    ➔ Connect the BLACK wire to the negative (-) source terminal as shown in
    Figure 2-8.
    If the power leads are accidentally reversed, the in-line fuse will blow. If this
    happens, recheck the polarity of the connections with a volt-meter (VOM) and, if
    necessary, reverse the leads for proper connection.
    Then, replace the fuse.
    If the unit will not turn on and you suspect that you may have reversed the
    power connections, check the DC power lines all the way back to the battery. If
    the polarity is not correct, properly reconnect the leads and try again.

    33

    The unit is internally protected
    from accidental reverse polarity.
    Reversing the power leads will
    not damage the unit, it will
    simply not turn on.

    Grounding the Display Unit
    One very important requirement in installation of shipboard electronics is to
    obtain the cleanest, noise-free environment possible so each piece of electronic
    equipment can work to its best performance levels. This requirement is
    accomplished by assuring a proper connection from each equipment to the ship’s
    RF ground system. The ground provides a drain for shipboard noise transmission
    and pickup.
    A separate ground wire of # 10 or # 12 AWG (# 10 recommended) should be
    connected from the ground terminal on the rear of the unit to the nearest
    connection point of the ship’s ground system.
    Normally, on a steel hull boat, a good clean connection to the hull provides a
    sufficient ground. On a fiberglass or wood hull, connection to a ground plate or
    to the engine block and other bonded groundwork should be acceptable.

    Connecting GPS/DGPS Sensor or Making
    NMEA0183 Data Connections (Option)
    When displaying the latitude and longitude of your vessel on the screen, or
    using the NAVIGATION mode, you are required to connect the optional
    GPS112 or DGPS212 sensor to the RADAR 1800, or input the data of
    navigational information in the NMEA0183 format from navigation equipment.

    Connecting GPS112 or DGPS212 sensor

    CAUTION

    When using the GPS112 or DGPS212 sensor, connect the 5-pin antenna
    connector attached to the signal cable of the sensor to the “GPS” connector at the
    rear panel of the unit.
    With this, it is possible to receive the necessary data of navigational
    information from the GPS112 or DGPS 212 sensor. It is advisable, however, to
    perform initial settings according to your conditions using the GPS SETTING,
    DGPS SETTING menu of the unit for more precise navigational information.
    Refer to p.91 and p.92 for the information about initial settings for each sensor.

    Section 2 Installation

    Only the GPS/DGPS sensors manufactured by JRC
    can be connected directly to the GPS connector at
    the rear panel. If those other than manufactured by
    JRC are connected, the equipment may be damaged.

    Making NMEA0183 data connections
    When receiving navigational data information in the NMEA0183 format
    from navigation equipment other than this unit, you are required to make a
    connecting cable using the 5-pin connector (model 6-282-5SG-325, CONXALL)
    and connect it to the “NMEA” connector at the rear panel of the unit.
    Connect the 5-pin connector and the connecting cable as shown in Figure
    2-9.

    the radar system. It is recommended that the radar be run in transmit
    mode for at least 10 minutes before adjusting the Preset Tuning in order
    to stabilize the transmitter circuit first. It is also recommended to adjust
    the Preset Tuning first as the other adjustments will be easier to do after
    that. If Preset tuning is not correct, then the Auto Tune may not work
    or may not work correctly and receiving targets will be decreased or
    eliminated. If Preset STC is up too high the loss of closer in targets will
    occur. These are the 2 most important adjustments for viewing target
    echos. Bearing alignment and Range (Timing) adjustments are

    There are three bearing modes.
    [HUP]

    Most radar operators are familiar with seeing the radar picture aligned
    with the bow of the vessel. This type of radar display orientation makes
    it easy to look out the windshield and identify the radar’s targets as they
    are positioned relative to the ship’s Heading line.
    [NUP]

    North up mode means the radar picture is positioned just like your
    marine chart. 000˚ on the radar bearing scale is the same as True or
    Magnetic North.
    This mode requires an appropriate Heading input via COMPASS input
    or NMEA input.

    DISPLAY MODE (BEARING)

    [CUP]

    If having the radar picture turned around on the screen in the NUP
    mode is confusing, you could select the CUP mode. The CUP mode
    lets you rotate the radar picture so the vessel’s basic Course Heading
    (and the Heading line) point at 000˚ on the bearing scale, similar to the
    HUP mode. In CUP mode you can again reference the targets by
    looking out the front window.
    Note however, if the vessel changes direction, the radar picture will not
    shift on the radar display in sync with the ship’s Heading changes. This
    keeps all target plots stable and also provides a clear visual reference to
    the operator on the impact of the vessel’s Heading shifts to the targets
    around his vessel.
    This mode requires an appropriate Heading input via COMPASS input
    or NMEA input.

    movement or behind the moving targets. Selecting “OFF” is no trails.
    The numerical selections, 0.5, 1, 3, and 6, represent the length of the
    “trail time” in minutes. For example, if 3 minutes is selected as the
    interval, the trail presents the last 3 minutes of the target movement.
    This provides a visual indication of a targets relative speed and course.
    “CONTINUOUS” provides a continuous trail.
    If range scale or bearing mode is changed, or offset display position
    by the offset function, or changed display mode “RADAR” full to
    “RADAR/CHART”, the trails will be cleared and new trails will be
    redrawn to the screen.
    The trails are drawn for anything that move on screen, including
    sea gulls, sea clutter, buoys, lobsterpots, and shoreline. In general, it is
    better to use the trails feature away from harbor and the shoreline to
    avoid a cluttered display and to concentrate on trails of target vessels.
    If own vessel changes the course all trails are influenced in HUP
    mode, it is better to use the trail feature in NUP mode or CUP mode.

    Setting GUARD ZONE
    The Guard Zone may be a zone completely surrounding the vessel
    or a partial trapezoidal zone to monitor targets entering or departing
    the specified area.
    Targets entering or leaving the guard zone will sound audible and
    visible alerts to the operator. In the “IN” alarm mode, an alarm will
    sound if a target enter the area. In the “OUT” alarm mode the alarm
    will sound if a target leaves the prescribed area. This type of alarm is
    useful for monitoring during an anchor watch, when cruising with
    other vessels, pair trawling, or towing operation.
    An alarm is sounded when any (apparent) target returning an echo
    above the noise threshold is detected. If sea clutter, or other incidental
    echoes trip the alarm, adjust the gain control and/or the sea clutter to
    avoid this false alarming.

    Section 3 Operation

    SART (Search and Rescue Radar Transponder) is life preserving
    device approved by GMDSS which is used for locating survivors in the
    event of a disaster or distress. SART operates in the 9 GHz frequency
    band. When it receives a radar signal (interrogating radio wave) of 9
    GHz transmitted by a rescue ship or aircraft radar, SART transmits a
    series of response signals to the searchers to indicate the distress
    position.
    In order to see the SART or radar beacon mark on the radar screen.

    ATTENTION
    When above settings q to t are made to
    display SART signals, objects around the own
    ship will not appear on the radar screen, so
    perform thorough visual monitoring of the sea
    area around the own ship to avoid any collision
    or stranding.
    Further, when more than one radar systems are
    mounted, while using a 9 GHz band radar for
    searching SART signals, be sure to use another
    radar as an ordinary radar to perform
    monitoring of object around the own ship to
    avoid any collision, check of the position of the
    own ship to avoid any stranding, and so on.

    • In this item, you can perform the initial settings when JRC’s GPS/
    DGPS sensor GPS112 or DGPS212 is connected to the RADAR
    1800. The menu includes both basic settings and initial settings. The
    basic settings reflect the general GPS/DGPS sensors and the initial
    settings reflect the beacon module of the DGPS sensor. Before setting,
    you need to set the clock built in the plotter using CLOCK ADJUST.
    Note:
    • Use TX COMMAND to send the values set in the following settings.

    VESSEL POSITION (Setting the vessel position)
    • In this menu, you can set your vessel’s current position. It will take
    about 20 minutes to complete the positioning through the GPS/
    DGPS when you turn the power on for the first time or after you
    perform the master reset. You can save time, however, by setting your
    vessel’s position, as well as time difference and antenna height
    described below.

    TIME DIFFERENCE (Setting the time difference)

    Section 3 Operation

    • In this menu, you can set the time difference between UTC
    (Universal Time Coordinate) and the local time.

    ANTENNA HEIGHT (Setting the antenna height)
    • In this menu, you can set the antenna height (from the sea level) of
    the GPS/DGPS sensor.

    GEODETIC DATUM (Setting a geodetic system)
    • In this menu, you can set the data type of the Geodetic System the
    GPS/DGPS sensor uses. In preparing charts or maps, cartographers
    rely on a particular geodetic datum or scaling system (Geodetic
    System) on which to calibrate the Latitude/Longitude coordinate
    structure onto their charts. The GPS/DGPS sensor also calculates the
    vessel’s position using the same Geodetic System. If the data type used
    in the Geodetic System by cartographers and the GPS/DGPS differ,
    the positions calculated by the GPS/DGPS may be considerably
    different, up to 200 m, from those in the charts. Therefore, it is
    necessary to set this item so that both sides use the same data type.
    The data type used is normally listed in the margin on the chart. Set
    the same data type.
    There are 46 types of data available currently. (Refer to “Geodetic
    System Table” p.140)

    FIX MODE (Setting the fixing mode)
    • In this menu, you can set the geodetic mode of the GPS/DGPS
    sensor. When the GPS is connected, 3D provides more precise data
    than 2D. When the DGPS212 is connected, the AUTO mode is
    selected regardless of this setting.

    94



  • Page 96

    HDOP LEVEL (Setting the HDOP level)
    • In this menu, you can set the upper limit of the HDOP level using
    this item. The HDOP level indicates the geodetic precision
    determined by the constellation of the GPS satellites. Precision is
    increased as this level decreases and vice versa. The constellation of the
    GPS satellites changes constantly and the HDOP level changes
    accordingly. The GPS/DGPS sensor stops positioning when the
    HDOP level exceeds the upper level specified in this item. Therefore,
    if you set a smaller value as the upper limit, the precision is improved,
    but the possibility of interrupting positioning becomes larger.

    AVERAGE (Setting an interval to average the data)
    • In this menu, you can set an interval to average the positioning data.
    If you set a longer interval, the positioning data becomes more stable.
    If you set a shorter interval, you can reflect your vessel’s movement
    changes more quickly, though the positioning data becomes less
    stable.

    EXCLUDE SAT (Setting the satellite number not
    used)

    Section 3 Operation

    • In this menu, you can set the satellite numbers so that excluded
    satellites are not used for positioning. The GPS/DGPS sensor does
    not use these excluded satellites for positioning.
    The satellite number not used cannot be set by GPS112/DGPS212
    themselves.

    DGPS SETTING
    • In this menu, you can perform the basic settings of the beacon
    module of the DGPS sensor.

    the display unit is using the antenna in transmission status. Then,
    after the specified time, the BZ signal error occurs when the rotation
    signal from the antenna is cut off, which should be used only when
    automatically turned OFF.
    In the normal case (No Interswitch kit), be sure to set it to
    "CONTINUOUS".

    WARNING
    Perform BZ alarm settings with the owner's
    authority.
    When the BZ setting time is limited, monitor
    the alarm constantly. If the antenna is
    stopped, and the alarm function stops with

    Maintenance

    SECTION 4
    General

    It is necessary to perform the maintenance services listed below to keep the
    RADAR 1800 in good working conditions.
    Proper maintenance of the RADAR 1800 minimizes the possibility of
    machine failures.
    The maintenance operations that are common to all components of the
    RADAR 1800 are listed below.
    q Cleaning
    Remove dirt, dust, or water-spray from the RADAR 1800 enclosure and
    keep it as clean as possible. Use a dry lint-free cloth.
    w Screw inspection
    Check the screws used to assemble and secure the components of the
    RADAR 1800 for loose connection.
    e Cabling check
    Check the cables connecting between the components (between the scanner
    unit and display unit, display unit and power supply, and display unit and
    optional devices) for poor connection.

    CAUTION

    Scanner Unit

    Section 4 Maintenance

    When servicing the RADAR 1800, be sure to turn it
    off to prevent electric shock. If a rectifier unit is
    used, in particular, turn off power to the display unit.
    Note that voltages from the rectifier unit are always
    present even if the radar is stopped.

    When inspecting the scanner unit of the RADAR 1800, be sure to turn off
    power to the display unit.
    Keep watches or magnetic cards away from the modulator block as it
    contains a magnetron having a strong magnetic force.

    Radome Scanner Unit
    q Radome
    A radome surface contaminated by smoke, dust, or paint would cause
    attenuation or reflections of radio waves, resulting in reduced radar
    performance. Periodically check the radome scanner unit. If it proves dirty,
    wipe the radome surface with a soft lint-free cloth moistened with alcohol or
    damped cloth.
    *Never use solvents such as thinner, gasoline, benzene, trichlene, and ketone.
    w Lubricating gears
    • Apply grease to gears evenly using a knife or brush. This lubrication needs
    to be performed at least semiannually. The shorter the lubrication period,
    the longer the gears will endure.
    Use Mobilux No.2 from Mobile Oil Co,. ltd. Or equivalent.
    • Check the mounting bolts for loose connection occasionally.

    Display Unit
    Cleaning the Display Unit Screen
    Dust on the LCD would reduce the transparency and make the video image
    dim.
    Wipe the screen surface with a soft lint-free cloth (made of flannel or cotton).
    A cloth moistened with an antiseptic agent would cause little problem. When
    using it, wipe softly; never rub the screen surface with force.

    Radar Basics

    The role of radar operator is to analyze the echos on the screen to assist in
    proper navigation and safety of the vessel. To do the best job it is imperative to
    understand the operation including advantages and weaknesses of radar. The best
    way to learn is in good visibility conditions so proper comparisons can be made
    between visual sightings and the representations presented on the radar display.
    Some of the advantages and uses of radar are: the monitoring of other vessels in
    order to avoid collisions, recognizing buoys and navigation marks for assistance in
    entering and leaving port, establishing own ships position by measurement of
    bearing and distance to land/islands and comparing to charts, and recognizing
    heavy rain clouds. The following sections explain the screen representations.

    Strength of Reflection from the Targets
    The strength of a radar target depends on several conditions including
    distance from you, size of the target, the height of your radar antenna, height of
    the target, and the radar reflective properties of the target surface towards you.
    Especially coastlines can be deceiving as a higher perpendicular surface will reflect
    the radar beams back better than a beach which is sloping up and has no surface
    to bounce the beams back. As shown in the illustration the closer beach may not
    show as a returned echo while the mountain furthur back does show.

    MOUNTAIN DISPLAYED ON THE SCREEN

    SEA SHORE LINE NOT DISPLAYED ON THE SCREEN

    Sea Clutters
    When the sea is rough, bright noise is reflected from the wave tops especially
    closer in around the center of the screen. The higher the waves, the stronger the
    noises. Sometimes breakers or even ships wakes may show on the screen.

    Section 5 Principle

    False Echoes
    Shadows
    Owing to the location of a scanner, surrounding masts and structures may
    block the propagation of radar waves in those directions. This can be noticed by
    thin or weak shadow sectors in the nearby sea clutter returns. Since these shadows
    are fixed due to the physical surroundings on the vessel, it is necessary for the
    operator to be aware of them and realize that targets in those sectors may be
    weaker or blanked out.

    Side lobe
    The radar beam has a main beam and weaker side lobes to either side of the
    main beam. Because of the side lobers, a series of weaker targets in an arc the
    same distance as the real target can show as in the Figure 5-2. This usually occurs
    mostly with stronger target returns and it is usually easy to pick out the stronger
    echo in the arc as the real target.

    Figure 5-2

    False Echo by Secondary Reflection
    When an object is in the vicinity of own ship and in some occasion, 2 echoes
    appear on he screen that one is true echo and another is a false echo resulted from
    secondary reflection of radar beam from ship’s structure such as funnel or mast. In
    this case, false echo appears in the direction of funnel or mast from the radar
    scanner as Figure 5-3.

    False Echo by Multiple Reflection
    As Figure 5-4, when the own ship is in side by side with a large ship or
    building, evenly spaced plural echoes appear in one direction. In this case, echo is
    the nearest echo to the own ship.

    Figure 5-4

    Radar Interference
    When other ship’s radar operated in same frequency is the vicinity of own
    ship, Radar interference pattern appears on the screen as the Figure 5-5. As
    interference pattern appears in a form of dotted stripes and moves around the
    screen but the pattern is not stationary, discrimination from the true target is
    rather easy.
    The IR control will help reduce or eliminate this noise. In severe cases
    shifting the PRF may also be necessary.

    GPS/DGPS Basics
    GPS
    The Navstar/GPS system is a satellite-based radio navigation system designed
    to provide global, continuous 24 hour-per-day, all weather, accurate position data
    for navigators. The GPS(Global Positioning System) is based on a GPS sensor’s
    ability to accurately measure the propagation time of signals transmitted from
    orbiting satellites in your sensor.
    The satellites transmit accurately timed signals along with a navigation
    message which includes the satellite’s position (orbit or ephemeris data), precise
    time (clock) correction signals, and almanac data for the complete constellation of
    satellites.

    GPS System
    Figure 5-6

    Section 5 Principle

    120

    The complete constellation will consist of 24 satellites (3 spare satellites) in 6
    orbital planes. Four satellites are equally spaced in each plane.
    The four satellites equally spaced in each plane circle the globe once every 12
    hours at a distance of approximately 20,000Km from the Earth.
    The satellites continuously broadcast their navigation messages at a frequency
    of 1575.42MHz (for civilian use). The message is repeated every 30 seconds.
    Superimposed on the navigation message is a high rate C/A (coarse/acquisition)
    code used for precise positioning measurements and positive satellite
    identification. The C/A ID code permits the user to determine and select the
    “best satellites” to use in position calculations.
    If it were possible to measure “true satellite ranges” directly, it would only be
    necessary to track data from any two satellites to obtain a vessel’s latitude/
    longitude. In actual practice, for marine navigation, a minimum of three satellites
    are normally tracked in order to reduce the sensor’s own internal clock timing bias
    error.
    By calculating the ranges of four satellites, the clock timing bias error can be
    eliminated and the vessel’s three dimensional position can be determined.



  • Page 122

    Differential GPS (DGPS)
    The differential GPS comprises a reference station with its position(latitude
    and longitude) accurately known, a beacon station for radio broadcasting of
    DGPS correction data, and user-owned GPS sensor equipped with a differential
    correcting function.
    The GPS sensor is used to fix the position of the reference station whose
    position is accurately known and to compare this with the actual reference station
    position to get range errors. The range errors are transmitted to the beacon station
    as the DGPS correction data and are broadcast from the beacon station to the
    user. This DGPS correction data is received by the user-owned beacon receiver,
    and is sent to the GPS sensor. The GPS sensor calculates its own position by
    adding the correction data to the actual data transmitted from the satellites.
    Compared with the fixed positioning provided by existing GPS sensors, the
    DGPS system calculates the position with a very small error not exceeding 10%
    of the measure.

    Wide Area Augmentation System (WAAS)
    Wide Area Augmentation System (WAAS) is a system that improve GPS
    position fixing accuracy. GPS signal errors are observed at multiple ground based
    reference stations. The data are gathered to the master station, then correction
    values are comprehensively calculated. The correction values are transmitted to a
    geostationary satellite, then they are broadcasted to ground based users. Ground
    based differential GPS system, similar to a beacon differential GPS, supports
    300km in radius around the beacon station, but the WAAS vastly expands the
    service area to mountainous and off-shore regions. The WAAS covers the Eastern
    Southern and Mid-western United States with INMARSAT Atlantic ocean
    region-west satellite, and covers the Western United States, Alaska and Hawaii
    with INMARSAT Pacific ocean region satellite.
    The WAAS service is free of charge because The WAAS is operated by the
    Federal Aviation Administration that is governmental entities.

    Availability of WAAS
    Currently, the WAAS is doing broadcast tests. Full-scale operations of the
    system is scheduled to the end of 2003. During test operations the WAAS can be
    used with almost no time-lapse problems, but it causes infrequent transmission
    stoppage and some degraded accuracy correction. Further, some functions of the
    GPS112W may be not available for use during the test transmission period due to
    system upgrades carried out to improve performance.
    JRC is not liable for any loss while using the WAAS satellites during test
    transmissions, or any malfunction of the GPS112W by the upgrades of WAAS
    system.

    Interswitch (option)

    Interswitch is a device used to switch the antenna between two display units.
    The configuration is as shown on the attachment: Set the standard display
    unit and antenna to plus; this is then the junction box and two Interswitch cables
    and specified sub-unit.
    In standard operation, the display unit that is powered up can use the
    antenna.
    When the display unit that is powered up is using the antenna, and the other
    display unit is turned ON, that display unit can access the antenna. The display
    unit that can not use the antenna is turned OFF by a function that automatically
    cuts the power.

    Installation
    Table 1 is a summary of the operation of the display unit when the jumpers
    in the switchbox have been set. The mode for setting 1 or 2 can be selected
    depending on the jumper settings in the Interswitch box. The factory default
    setting is 2 (settings 3 and 4 are prohibited).
    In setting 1, operation is standard as noted above. The last unit to be turned
    ON can use the antenna, the display unit that is already powered up can not use
    the antenna and has its power turned OFF at the same time.
    Setting 2, (factory default setting: initialization setting) is applicable when
    display unit 1 is installed in the cabin or someplace similar, and when display unit
    2 is installed on the upper bridge or someplace similar.
    In this setting, the power to display unit 1 is not turned OFF even if display
    unit 2 is turned ON, however, display unit 2 can use the antenna.
    However, while the display unit 2 is turned ON, and power is turned ON to
    display unit 1, then display unit 2 is turned OFF and display unit 1 can use the
    antenna. (Display unit 1 controls the power to display unit 2.)
    Therefore, even if display unit 2 on the upper bridge is ON, by turning ON
    the power to display unit 1 in the cabin, the power to display unit 2 is remotely
    turned OFF. Which then makes it possible to turn OFF power to both units from
    the cabin by turning of the power to display unit 1.

    Unit Connecting Cable

    Section 6 Inter Switch (option)

    Be sure that the positive and negative polarity for the power connected to
    both display units is the same.
    It is necessary to connect the 12 V connector and GND connector to the
    same terminal. The voltage is 12 V.
    Also, the switchbox is not sealed against leaks, be sure to install it indoors
    where it will not be splashed with seawater or liquids.
    In the default setting (setting 2), the settings are made for display unit 1 to be
    installed in the cabin, and display unit 2 to be installed in the upper bridge or a
    similar place. (TB 1: Jumper between 1 - 2; TB 2: Jumper between 2 - 3)
    The following setting example is written as if display unit 1 (the display unit
    that is normally ON when under way) is in the cabin, and display unit 2 is
    installed in the upper bridge or someplace similar.
    (1) Connect both display unit 1 and display unit 2 to the J1 power cable, be
    careful to connect each power cable as noted, connect the "RED" line to the
    12 V power positive side, and in the same way connect the "BLACK" to the
    negative.
    (2) Connect the J2 of display unit 1 to the CFQ-6550 cable, connect one side to
    the "MASTER (CABIN)" of NCZ-1432 (switchbox below).
    (3) In the same way, connect the J2 of display unit 2 to one of the CFQ-6550
    cables, connect one side to the "SLAVE (UPPER BRIDGE)" in the
    switchbox.
    (4) Connect cable CFQ-6531, which runs between the antenna and the display
    unit, to "TO SCANNER" in the switchbox. At this time, cut off the black
    waterproof cap with a razor knife or box cutter.
    Read the following only if you are entering NMEA data for GPS or similar
    kinds of receivers.
    (5) Connect the cable from the GPS receiver (DGPS200 etc.) to the J3 (GPS) of
    display unit 1.
    (6) Connect the connectors attached to the display unit to the cables in the
    following way, connect the J4 of display unit 1 to the J3 of display unit 2.
    In this case, power to the GPS receiver is provided from display unit 1, and the
    GPS receiver will not operate, and NMEA data will not be input, if display unit 1
    is not turned ON.

    Operation
    Section 6 Inter Switch (option)

    The following is for the jumpers in the junction box. (Setting 1)
    TB1 = 1 - 2, TB2 1 - 2
    Display unit 1 and display unit 2 can alternately use the antenna each time
    they are turned ON, whichever display unit is already ON is turned OFF.
    Example:
    Turning ON display unit 2 while display unit 1 is ON turns OFF the power
    to display unit 1. After display unit 2 has been running for 1 minute and 30
    seconds the magnetron is finished pre-heating, allowing it to use the antenna for
    transmission.
    In the same way, turning ON display unit 1 while display unit 2 is ON turns
    OFF the power to display unit 2, allowing it to use the antenna.

    The following is for the jumpers in the junction box. (Setting 2)
    TB1 = 1 - 2, TB2 = 2 - 3
    The power to display unit 1 stays on even when the power to display unit 2 is
    turned ON.
    However, access to the antenna is given to display unit 2 if display unit 2 is
    turned ON.
    When display unit 2 is turned ON, and display unit 1's power is turned ON,
    the power of display unit 2 is automatically turned OFF, and display unit 1 is
    allowed access to the antenna.
    Example:
    Display unit 1, which is normally ON and used when underway, from
    departure to arrival, also provides the electric power to operate the GPS receiver, it
    is used to store and display the ship's route.
    By turning ON display unit 1, while display unit 2 is operating, display unit
    2's power can be turned OFF, and display unit 1 gets priority access to the
    antenna.
    By turning ON display unit 2 while display unit 1 is transmitting, because
    the priority access to the antenna moves from display unit 1 to display unit 2 an
    antenna rotation error (BZ error) occurs at display unit 1.
    Therefore, to turn ON display unit 2's power, first put display unit 1 into
    standby, then put display unit 1 into standby status, and then turn ON display
    unit 2.

    CAUTION
    Section 6 Inter Switch (option)

    While one display unit is transmitting, and another
    display unit is turned ON, depending on the settings
    the power may be turned OFF. In cases like this, be
    sure that transmission status has changed to
    standby status, then turn ON the power to the other
    display unit.
    Immediately after turning OFF the power to the
    display unit, and the turning ON the power again,
    absolutely wait at least five seconds before turning
    it ON. The machine may not operate normally.
