A Study On Automatic Identification System For Preventing Ship Collisions At Sea

With the development of worldwide economy, the shipping gets its chance too. People accordingly ask for higher quality of navigation and communication equipments. In last century, almost every port installed VTS and all sea going ships installed Automatic Radar Plotting Aid(APRA). However, Vessel Traffic Service(VTS) and APRA can not recognize the target directly which becomes an increasingly serious problem for us. In that time, Automatic Identification System(AIS) came out of needs.The installation of AIS promotes effectively and ensures that of avoiding collision between ships, navigation safety, protection of sea environment, and VTS. Considering the importance and necessity of Automatic Identification System(AIS), on the basis of being familiar with AIS, I've known its installation and usage, analyzed performance effect of AIS for preventing collisions at sea, studied the application of AIS for preventing collisions at sea, had the concept of marine intelligent communication system and my corresponding suggestions to improve of AIS, and prospected the future of AIS.
