JHS-182, advanced technology fit in a compact design known for its long range
AIS 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. The AIS can "see around corners", allowing avoidance of dangers before
visual contact has been established. All ship's information including static and
voyage related data such as the ship's name and cargoes, as well as its dynamic
navigational information, i.e., position, course, and speed can be transmitted
and received. 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 (Automatic Identification System).
Smallest AIS Transponder
unique compact antenna transponder design consists of the VHF antenna, GPS
antenna, VHF transceiver and data processor. The new JHS-182 is downsized using
highly reliable LSI technologies.
Large Screen Ensures Comfortable Visibility
JHS-182 has a 5.7 LCD screen display, which presents the information given from
the target ship list and plotting viewer with clear visibility.
JHS-182 consists of three components, transponder, display and a connection box.
The components are light and compact. This new concept also allows for easy
setting up as only one coax cable is required between the transponder and
junction box, contributing to an easier setup with less error and significantly
reduced installation time.
Stress Free Operation
AIS has become an important piece of navigation equipment to assure safe
navigation. A simple joystick and jog-dial operation allows for easy navigating
through the AIS real-time information.
Integration with Navigation Equipment
JHS-182 is an important piece of navigation equipment onboard for collision
avoidance and maneuvering. The information broadcasted from other ship's
displayed on the AIS, together with the geographical information shown on the
radar or ECDIS provides highly applicable data for strategic decisions and for
prompt contact with other ships.
AIS target on RADAR/ECDIS
AIS is an important key device used to indicate AIS target symbol and
information on RADAR/ECDIS screen:AIS and ARPA targets are shown on the same
screen of the radar/ECDIS. Comparing these targets is very useful, as it
provides the maneuvering conditions of other ships at a glance, allowing for
safe and effective navigation. The course and speed from other ships, received
from AIS target information are displayed as a vector symbol. AIS targets are
more accurate than ARPA, which makes AIS information highly suitable for
collision avoidance. The AIS symbols are continuously displayed on-screen
without the influence of the radar characteristics, unless other ships are out
of VHF range. The AIS targets are never shielded by ground, rain or cloud
reflections, nor are they eliminated by adjustments of anti-sea or anti-rain
clutter. Also, it is easy to switch between AIS target symbols.
Remote Diagnostic System
Diagnostic System (RDS) is a unique function that is capable for remotely
monitoring and analyzing JRC equipment. The JHS-182 has this function
integrated. When connected to a RDS server and Inmarsat, allows for prompt
action and service for any faults that may occur in the AIS system.
