Officially, at the end of 2019, a correction of the Baltic Sea Location was published in the Sailing News, which at the same time informed about the change of the operator of the Polish GMDSS Responsibility Zone, excluding Witowo Radio so far and transferring the Polish Rescue Radio (SPL) service. Starting from 2020. PSL began operational service of GMDSS in Poland. This article is the first presentation of the experience from the implementation of this project “Construction of maritime communication system in danger, GMDSS-PL”. mainly focusing on the OpenEye_ GMDSS operating system. In addition to the technological layer of the project, the procedural and organizational part of the GMDSS service has been equally important. The maritime emergency response system can be compared to the operation of 112 on land. The operation and efficiency of this system directly translates into human health and life as well as the quality of the marine environment around us. The technical means provide a high quality and certainty of business continuity. Communication in danger is one of the basic and most important tasks of the Polish maritime service. At this point, all operators and GMDSS services in the Maritime Office in Gdynia and Szczecin deserve praise.

Content available The radio operator decision support system model
EN
The article proposes a model of the system supporting the decision-making process relating to the radio operator on board a ship after a distress alert is received by a Digital Selective Calling (DSC) controller working on VHF channel 70. The model is aimed at the implementation into the system of radiocommunication event management. The system takes into account the existing Radio Regulations. The model makes use of Petri nets, which are elements of graph theory. The time domain is comprised in the developed graph, and the states (places) and transitions capable of autonomous functioning are separated, as are those places and transitions requiring direct operator action based on empirical knowledge.

This article presents the structure of a model of the allocation of radiocommunication events at coastal radio stations, land-based satellite stations and on vessels in sea area A3. The propagation of radio waves in the HF band has been analyzed to examine the range of various radio stations and their capabilities of establishing communication between each other. We also present methods of modeling and displaying the deployment of individual stations, of presenting radiocommunication events as a function of time using time diagrams, as well as the manner of the chronological presentation of radiocommunication events and related decisions. It has been shown that there is a relationship between the effectiveness of communication and propagation conditions that is strongly dependent on the time-of-day. We present the need to develop a decision support system for the radio operator on the bridge.
