Developments of Interface for VHF, MF/HF Communication Using DSC in GMDSS Services in the Framework of E-navigation Concept

It is proposed the description of interface for VHF/MF/HF for simplification of DSC communication for implementation in the frame of conception developments in GMDSS services, applied to Maritime Mobile Services. This interface is realized within its integration with INS by an appropriate way on the base of common communication protocol for all three DSC communication sub bands in standardized and harmonized format and significantly simplifies the DSC user interface. It is very important for application in Maritime services, including GMDSS services, VTS services and SAR service. Suggested approach for improving DSC communication is based on the three main outputs of e-navigation strategic direction development related to the integration of communication and navigation equipment/systems, including standardized mode of operation. Implementation of the standardization demands to include in this integration the satellite AIS system. The feasibility of the proposal is supported by the existence of relevant IEC standards and IMO documents.
