1.1 Outlines
Automatic Identification System (AIS) is a maritime navigation and radio communication system.
This system intends to enhance the safety of life at sea, the safety and efficiency of navigation
and the protection of the marine environment by communicating navigational information
automatically on VHF channels between ship and ship, ship and shore.
JHS-182 meets the requirements of the SOLAS Conventions for the Class A shipborne
equipment of the universal AIS. JHS-182 mainly consists of AIS Transponder, Connection Box
and AIS Controller. The combined antenna and transponder design allows installation at any
convenient location on any vessels. The small and simple design controller allows easy
installation and operation. Moreover, easy equipment that connects a connection box and these
each equipments by one cable is designed. JHS-182 employs the latest technologies such as
digital signal processing, circuit integration technology, and these technologies ensure high
performance and high reliability.
1.2 Features
● Fully Comply with International Regulations
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 is designed to meet the requirements of the SOLAS Conventions for the Class A
shipborne equipment of the universal AIS and fully complies with international regulations: IMO
MSC74(69) Annex 3, ITU-R M.1371, IEC61993-2, IEC60945 etc.
● Combined Antenna and Transponder for Ease of Installation
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 employs the combined antenna and transponder design. This design allows installation
at any convenient location on any vessels. For the connection between abode deck component
and below deck component, only one cable is needed.
● Increased Probability of Vessel Detection
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 is equipped with a guard zone alert function. When preset guard zone range and other
vessel enters into the zone, JHS-182 indicates and sounds the alert. This function enhances
probability of vessel detection.
● Recognition of Own-group Vessels
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 is equipped with a recognition of own-group vessels function. When preset own-group
vessels’ identification in advance, the display indicates the own-group vessel sign. This sign
allows easy recognition of own-group vessels.
● Self-diagnosis Function
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 is equipped with a built-in automatic self-diagnosis function. This function allows easy
maintenance and high system reliability.
● System Integration Availability
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
JHS-182 is equipped with various interfaces. These interfaces allow system integration and future
expansions.
