A new generation of GMDSS simulation and evaluation system is developed for the training of global marine distress and safety system. The Simulation System provides an integrated platform for the simulation training of multiple marine communication equipments. The simtdator has many advanced functions such as real - time communication simulation, routine operation demonstration and automatic evaluation. This paper describes the development intention and the basic configurations of GMDSS simulator, and presents a design and construction of server/client to develop the system. Then, some key technologies are introduced, such as the Bayes estimation, the integration method of modules, INMARSAT communication model and the implementation of data communication. Experiments indi- cate that the system has satisfactory performances for the actual training.
