Features
The JLR-21 GPS compass continues the success of its predecessor, reaching
a new level of performance and stability with many new features and
enhancements.
This system is also known as a 3D Dynamic Sensor™ (3-Direction Dynamic
Sensor), which besides giving heading information, is designed to provide
highly accurate information of the ships movement in all axis.
Display Modes
The JLR-21 incorporates many display modes readily available on a highly
visible 5.7 inch LCD display. The display is fully dimmable and the keys are
also backlit, making it easy to operate in low-light settings on the bridge.
Simple Operation
The compact design of the JLR-21 incorporates an intuitive interface,
providing enhanced ergonomics and user friendliness. The logic of the
controls and excellent on-screen menus will greatly shorten most users’
learning period.
Heave Compensation
The JLR-21 has heave functionality built-in as standard. In rough ocean
conditions (with high waves), the GPS compass can correct up and down
(attitude), movement. This is especially useful for fish finders and sonars on
fishing vessels where high waves are compensated for with up to 20 cm accuracy,
providing better potential for a profitable catch.
High Speed Update
The JLR-21 supports Speed Over Ground (SOG) and Course Over Ground (COG). The
position, SOG and COG are updated every 200 milliseconds (which is 5 times
faster than previous model JLR-20), delivering high accuracy.
High Speed Tracking
The GPS compass has its origins as a direction sensing system, but the JLR-21
goes far beyond that. The JLR-21 provides heading accuracy of 0.5°. Heave
accuracy is 20 cm or better and roll and pitch is 0.5°. The tracking Rate of
Turn (ROT) is 45° per second.
See the comparison between previous GPS compass model and this new model.
Highly Visible Display Modes
All information is displayed on a highly visible 5.7" LCD display. Many
display modes are readily available and selectable from the menu. The compass
rose, steering, navigational data, ROT and GPS information are easily
accessible. The control panel is fully dimmable, allowing you to adjust your
display preferences at your own convenience
Antenna Design
The
processor is built into the antenna. Eliminating alignment between antenna and
processor found in separate systems, therefore contributing to an easy setup
with less error and significantly reduced installation time. This concept also
reduces the installation costs as only a single cable is used between antenna
and display unit.
The outer shell of JRC’s new antenna system has a smooth surface. This slippery
exterior makes it almost impossible for birds to perch on the domes or for the
antennas to be completely covered in snow.
Should something interfere with the coverage, JRC’s proven antenna design
incorporates a layer of air that reduces possible blind spots, allowing for a
more precise heading than conventional systems.
Installation and Maintenance
The JLR-21 display is compactly designed and can be mounted virtually
anywhere. The three-antenna system is exclusively designed by JRC, making it far
more reliable than conventional antenna systems. The system has a short start-up
time (less than 2 minutes). Maintenance is not required, making it less
expensive to maintain than a standard gyro system.
High Speed Tracking Response
The GPS COMPASS has its origins as a direction sensing system, but JRC goes
far beyond this, with so many features integrated the GPS COMPASS enables higher
accuracy and stability. The JLR-21 provides heading accuracy of 0.5 degrees
and has a tracking Rate Of Turn (ROT) at 45 degrees per second.
JLR-21 and IMO Compliance
Traditionally, the means used to measure the heading of a ship has been a
mechanical gyrocompass and/or a traditional magnetic compass. With the adoption
of the new installation requirements in SOLAS-V, all passenger ships and all
ships from 300 to 500 GT travelling international routes can now install a new
technology directional sensor, the Transmitting Heading Device (THD).
JRC's
new JLR-21 has been approved as both a THD and a GPS. The THD approval allows
installation for as primary heading device on vessels up to 500 GT and for
vessels over 500 GT, two or more THD's could be installed depending upon
flag/class agreement
