1-1 Summary 

AIS  is  a  spearhead  equipment  to  provide 

voyage  information  such  as  ship’s  position, 

course,  speed,  etc.  real  time.  This  is  to 
protect  the  marine  collision  of  ships, 
obligations,  IMO  promotes.  AIS  induction 
makes  it  possible  to  recognize  the  existence 
of  other  ships  &  progress  status,  even  if 
radar  cannot  recognize  ships  around.  Under 
the poor field of visions, this can discern ship 
name, course, speed, which can make safety 
managements 

such 

as 

ship 

collision 

protection,  broad  area  control,  search  & 
rescue, etc, more efficiently. AIS is using VHF 
frequency. 

In 

1997, 

International 

Telecommunication 

Union 

World 

Radio 

communication  Conference  specified  two     
VHF frequencies (161.975 MHz - 87B channel 
& 162.025 MHz - 88B channel) for AIS. 

AIS-50N has high efficiency AIS Class B. It 
provides plotter functions, needed in voyage. 
Some functions can be used with 
establishment of option devices and sensors 
only.           
AIS-50N can be connected to outer devices, 
which have NMEA0183 or NMEA 2000. It can 
display relevant information.   
ex.) 

• Navtex 

 

• DSC VHF radiotelegraph 

 

• Auto Navigation equipment

 

 

1-2 AIS Technology Summary   

Communication methods of AIS are simplex, 
semi-duplex, or duplex operation of TDMA 
(Time Division Multiple Access). Allowance of 
occupied bandwidth is within 25

. These are 

classified into A Class & B Class transceivers, 
equipped on vessels, according to uses.   

 A Class transceiver

 

:

 Mandatory installed 

in international passenger ships & ocean-
going ships over 300ton. Ship positions 
should be reported on voyage.   

 B Class transceiver

 

:

 Mainly installed in 

small ships of length under 65 feet.   

 
4  data  information,  used  in  AIS  are  as 
followings. 

 Safety Related Message : 

This is 

according to requirement of message, 
includes voyage information or weather 
warning.   

 Static Information :

 IMO number, call 

sign & vessel name, length & width of 
vessel, vessel type. Renewal of antenna 
positions (division of vessel prow, stern & 
left light sides) of GPS is done every   

  6 minutes or when data are revised, or 

there is a demand. 

 Dynamic Information :

 Accurate mark of 

ship position, overall status, Coordinated 
Universal Time (UTC), course, speed, 
heading, voyage status, yaw angle & 
sensor information. These are renewed by 
interval of following table, according to 
change of speed & direction.       

 Voyage Related Information

 

:

 Draft, 

risk cargo, destination & ETA, route plan & 
boarding persons. Renewal is done every 6 
minutes or when data are revised, or there 
is a demand.
