Since 2004 a new technology has been introduced into commercial shipping, known as the Automatic Identification System (AIS). The AIS is a seaborne technology which transmits position and identification data as broadcast messages in short time cycles. In a typical range of FM transmitters the current ships data is continuously available in VTS centres or on the receivers of other ships. A large number of ships sailing in international regions are equipped with AIS. From technical point of view this is cause high cooperation ability in maritime traffic. The idea is to use this technology for an automated coordination of maritime traffic, maybe using a global acting system. An exact list of requirements for the underlying global communication system with regard to the relevant parameters of data exchange, e.g. message format and communication protocol, and requirements of global satellite navigation system should be analysed. All investigations base on real AIS data analysis and simulation procedures. The paper describes the structure of the simulation-model used and the approaches for solving the following problems: Analysis of traffic situation; generation of coordinated tracks; data exchange and communication-management. Finally the paper shows some system-requirements as well as some coordinating-system's benefits for the participating ships.
