JLR-31GPS compass3D Dynamic SensorTM506– the JLR-31 sets a new standard of GPS compass, with its renowned high performance and new features5.7-inch high visibility displayRoll, pitch, rate of turn and heave integratedIMO type-approved as Transmitting Heading Device(THD)and Satellite navigator(GPS)High speed tracking response (ROT 45°/sec)Wide range of new display modes availableDynamic heading accuracy 0.25° rmsJLR-31– featuresFeaturesThe JLR-31 GPS compass continues the success of its predecessor, reaching a new levelof performance and stability with many new features and enhancements. This systemis also known as a 3D Dynamic Sensor™, which besides giving heading information, isdesigned to provide highly accurate information of the ships movement in all axis.Heave compensationHeaveOFFThe JLR-31 has heave functionality built-in as standard.

In roughocean conditions (with high waves), the GPS compass can correctup and down (attitude), movement. This is especially useful forfish finders and sonars on fishing vessels where high waves arecompensated forwith 20cm rmsSentenceDataaccuracy, providingATTHeading, Rolling, Pitchingbetter potential forHVEHeavinga profitable catch.High speed updateHeaveONThe JLR-31 supports Speed Over Ground (SOG) and Course OverGround (COG). The position, SOG and COG are updated every 200milliseconds (which is 5 times faster than previous model JLR-30),delivering high accuracy.DataHeading, ROT, Rolling, PitchingPosition, SOG, COG, HeavingHigh speed trackingThe GPS compass has its origins as adirection sensing system, but the JLR-31goes far beyond that.

The JLR-31 providesan impressive heading accuracy of 0.25° rms.Heave accuracy is 20cm rms and roll and pitchfor both models is 0.5° rms. The tracking Rateof Turn (ROT) is 45° per second.On the right a comparison between previousGPS compass model (JLR-30) and the newmodel (JLR-31).JLR-31FeaturesRollPitchRate of TurnPositionHeaveSOG/COG graphHigh speed updateTrip logAnchor watchCCRPRMSTrend graphCycleEvery 20 milisecondsEvery 200 millisecondsJLR-30vvvvJLR-31vvvvvvvvvvvvG P S co m p a s s – a n e w l e ve l o f p e r fJLR-31– advanced technologyDisplay modesThe JLR-31 incorporates many display modes readily availableon a highly visible 5.7 inch LCD display. The display is fullydimmable and the keys are also backlit, making it easy tooperate in low-light settings on the bridge.Simple operationThe compact design of the JLR-31 incorporates an intuitiveinterface, providing enhanced ergonomics and userfriendliness.

The logic of the controls and excellent on-screenmenus will greatly shorten most users’ learning period.Antenna designThe processor is built into the antenna. Eliminatingalignment between antenna and processor foundin separate systems, therefore contributing to aneasy setup with less error and significantly reducedinstallation time. This concept also reduces theinstallation costs as only a single cable is usedbetween antenna and display unit.VQRZOD\HURIDLU*36VHQVRU· JRC proven high performance antenna designThe outer shell of JRC’s new antenna system has asmooth surface.

This slippery exterior makes it almostimpossible for birds to perch on the domes or for theantennas to be completely covered in snow.Should something interfere with the coverage, JRC’sproven antenna design incorporates a layer of airthat reduces possible blind spots, allowing for a moreprecise heading than conventional systems.VQRZ*36VHQVRU· Conventional antenna systemInstallation and maintenanceNNN-31506The JLR-31 display is compactly designed and can be mounted virtuallyanywhere. The three-antenna system is exclusively designed by JRC,making it far more reliable than conventional antenna systems. The systemhas a short start-up time (less than 2 minutes). Maintenance is not required,making it less expensive to maintain than a standard gyro system.Remote Maintenance System (RMS)JRC has the ability to cost-effectively monitor performance and functionality of the JLR-31 while atsea, significantly reducing downtime and maintenance costs.More at http://www.jrc.co.jp/eng/product/marine/rms/index.html ▸o r m a n ce a n d fe at u re sJLR-31– unique functionsCCRP and Anchor watchMeasuring toolThe GPS compass allows calculationof distance and bearing betweenany two points, supporting RhumbLines (RL) for the short legs andGreat Circle (GC) for long distancelegs.

With the adoption of the new installation requirements inSOLAS-V, all passenger ships and all ships from 300 to 500 GT travelling international routes can nowinstall a new technology directional sensor, the Transmitting Heading Device (THD).JRC’s new JLR-31, IMOIMO performance standardGross Tonnagetype-approved as bothFrom300GTto less than 500GTTransmittingHeadingDevice（THD）Transmitting Heading20GT or moreSatellite Navigator（GPS）Device (THD) and asSatellite Navigator (GPS),suits for the vesselsGyro compassGPS compassMagnetic compassas SOLAS-V requiredYesNoYesPeriodic maintenanceprimary heading sensorabout 4 hoursnoSettling timetypically 30 secondsor primary GPS.Middle speedLow speedTracking responseHigh speedAccuracyMagnetic influenceCorrectionGoodNoNoGoodNoYesBadYesYesfor latitudefor variation, deviationStandard in the boxOptions· Display· Antenna· Cables· Installation parts· Spare parts· Manual· Serial data cable· Sensor extension cable· Flush mount kit· AC power rectifier· DGPS receiverCables· Power cable display· Serial data cable· Display to antenna21.
