Architectural Concept of Shipborne Radio Communications GMDSS Network

Abstract

This paper introduces a new architectural concept of maritime radio communication in the function of  enhances GMDSS network and equipment within the Very High Frequency (VHF), Medium Frequency (MF) and High Frequency (HF) Ship Radio Station (SRS) terminals. Since its establishment in 1959, International Maritime Organization (IMO) and its member states, in close co-operation with the International Telecommunication Union (ITU) and other international organizations, notably the World Meteorological Organization (WMO), the International Hydrographic Organization (IHO), the International Mobile Satellite Organization (IMSO) and the Cospas-Sarsat partners, have striven to improve maritime distress and safety radiocommunications, as well as general radiocommunications for operational and personal purposes. This paper also reviews concept of GMDSS network, overview of antenna, types of shipborne VHF radios, radio portable survival craft VHF radios, ans shipborne MF/HF radios. In addition, the type of the radio Search and Rescue Transponder (SART), and airborne Radio - Automatic Identification System (R-AIS) transponder for maritime SAR operations are also described in this paper.
