AIS’s full name is Automatic Identification System. It is the joint achievement in research of IMO, IALA, ITU in recent years and also one of the indispensably safe equipment. It use SOTDMA technic to avoid the crash of ships, improve water carriage traffic safety, and offer ship navigation information to the water carriage management to make harbor frontage management easy.

 

The characteristics of AWAIS-1

 

●    Fully Complying with AIS Class-A shipboard equipment standard, and supporting all AIS functions.

 

●    Work automatically after power on and communicate automatically with AIS wireless network, which is without the operation of human.

 

●    Provide the serial interface of RS422/RS232, which is accorded with NMEA-0183 requirement.

 

●    Using 18~28VDC to supply power

 

●    The maximal instantaneous power is less than 40W, and the average watt loss is no more than 2W.

 

●    Compact casting mould casing is used on the principal machine which is sealed well, have good thermolysis

 

●    The principal machine is light and easy to install and maintain.

 

●    The function of sending and receiving Chinese message (patent).

 

●    Highly clear FSTN display, vector electronic chart can show the other ships around，such as its name or call sign, dimensions, type, position, course, speed, heading, navigation status and other pertinent navigation data.

 

●    Transferable Chinese and English interfaces
