Abstract
The ECDIS (electronic chart display and information system) is a new technology of modern navigation, sailing aims to ensure navigation safety, and improve work efficiency. AIS (automatic identification system) is a kind of can transmit large amount of information, obstacle, weather resistance, with ship shore - ship between information networking ability and close target indication of maritime communication system. And ship collision avoidance system is an important research subject in modern navigation technology, it in the prevention of ship collision accidents, ensure the safety of ship navigation plays a very important role. This paper developed based on ECDIS and AIS ship collision avoidance warning system. The simulation shows that the system is feasible.
