AIS
AUTOMATIC IDENTIFICATION SYSTEM
JHS-180
in accordance
with IMO carriage requirements and SOLAS (Chapter V, regulation 19),
passenger ships, vessels over 300GT on international voyages and all
vessels over 500GT are mandated to carry AIS. Existing vessels
will be required to carry AIS on a schedule that phases the
retrofits between July 1, 2003 and July 1, 2008. All vessels
built on or after July 1, 2002 are required to carry AIS. |

The JHS-180 AIS
(Automatic Identification System) is a ship borne system capable of
regularly broadcasting own ship's unique information and continually
receiving and displaying information broadcast from other vessels.
All vessels and VTS operators within VHF range and equipped with an
AIS transponder can continually receive and display information from
other vessels. New technology, SOTDMA (Self-Organized Time
Division Multiple Access) allows for interoperability and eliminates
channel congestion. The VHF data link enables the AIS to "see
around corners", allowing avoidance of dangers before contact has
been established. All ships information including Static and
Vo0yage related data such as the ships name and cargos, as well as
its Dynamic navigational informationn, i.e., position, course, and
speed can be transmitted and received. |
FEATURES
- JRC's JHS-180
is a single unit structure combining the antenna with the
transponder, guaranteeing easy system installation and cost
savings.
- Collision
avoidance is enhanced when interfaced with ARPA Radar equipment
and ECDIS.
- JRC's unique
Guard Ring feature with a guard zone setting gives the Officer On
Watch added warning of potential collision threat.
- Interface
connection to ship's sensors i.e.: Gyrocompass (NSK Unit option),
Speed Log, and Turn-Rate Indicator.
- Channel
management capability for areas without access to the worldwide
allocated AIS frequencies.
- Targets
masked by land, rain, or sea clutter can be easily identified on a
situational display.
- Warnings to
Navigators by the VTS or Coastal Authorities are displayed.
- Back up GPS
built-in
- Long ange
transfer of position data transmitted over Inmarsat C and Fleet
F77
- Fleet's ship
identification can be indicated.
- CH70 DCs
distress signal is received and displayed.
- Built-In
Diagnostics and On-line maintenance support.
