Abstract

Presently Electronic Chart Display and Information System (ECDIS) is stage-by-stage introduced on all marine merchant vessels. Due to its connection to various navigation sensors the ECDIS plays as the prime navigational mean of modern shipping. Further integration of ECDIS with the Very High Frequency (VHF) radio installation allows to enhance efficiency and operability of radio communication to increase safety of navigation. The aim of the present paper is designing the new ECDIS function, that provides interaction with the Digital Selective Calling (DSC) controller of radio communication. To implement this ECDIS function it is proposed to introduce modules for forming and processing DSC messages, module of Automatic Identification System (AIS) target marking and also input and output information ports by way of the connection to DSC controller is provided. The obtaining advantages due to realization the new ECDIS function are analyzed. They are expressed in the eliminating of hand operations with the DSC controller and replacing them by automatic call forming, increasing efficiency of navigation situation analysis while simultaneously lowering the risk of "human factor". In the article practicable maritime interfaces for DSC controller interconnection and symbols for displaying AIS targets are also considered and it’s reflection in the case of DSC activation for different radio communication priorities is proposed.
