Class-B (Automatic Identification System) vessel Automatic
Identification System, is installed in a ship collision avoidance
radio communications and navigation equipment, suitable for river,
harbor and open sea and other kinds of ships. Tianjin **2
Communication & Broadcasting Limited production of the AIS
Class-B ship automatic identification system, is the only
international organization uses internal first recognized CS-TDMA
technology, and full compliance with relevant international
standards for products, which are high-performance, high
reliability, high integration and so on.
AIS
Introduction
AIS
Class-BAutomatic
Identification System is a kind of Radio Communication and
Navigation Collision Avoidance Equipment installed in ships for
inland river shipping, port operating, coastal fishing, coastal
defense and other fields.
“Ship-Ship”System
This
equipment can achieve ship collision avoidance, information
exchange, ship positioning, distance alarming and other functions.
And to a large extent, it makes up the lack of ARPA radar. It can
avoid monitoring difficulties for objects in island shadow or heavy
rain and for small objects, so as to effectively avoid errors for
the ship identification, positioning accuracy and ship type
identification.
l AIS
equipment can, in the absence of the crew, automatically and
continuously send navigation data and status information to base
stations and equipment on other ships.
l AIS
equipment provide standard bi-direction RS**2/RS**2 interface and
can be connected to and can work with radar, electronic chart
display, information system, satellite navigation devices,
etc.
l When
vessels encounter special circumstances and need
help,“SRM”
button can be
pressed and send out SOS message to surrounding vessels, this SOS
message includes the vessel MMSI number and rescue
signal“MAYDAY”?
“Ship—Ship—Shore”System
l AIS
is an effective supplement to VTS. AIS can expand VTS working scope
and improve VTS accuracy, add ship identification function, so as
to improve the efficiency of the VTS operators.
l By
the use of AIS, all visualized vessels headings, routes, vessel
names and other information can be displayed on VTS electronic
chart, so as to improve marine communications and provide a
communication method for ship by voice and text to enhance vessels
global awareness.
l Use
AIS system to support ship tracking and identification and more
extensive data can be provided to VTS, this is a very important
information support to improve and enhance VTS
function.
l AIS
system can help ships and VTS to identify ships dynamic navigation
in radar blind area.
AIS Class-B ship-borne mobile station reporting
