GMDSS simulator

The simulator is designed for training and examination of seafarers that are going to obtain General Operator Certificate (GOC) or Restricted Operator Certificate (ROC). The GM TRAINER 6.0 simulates the electromagnetic environment created by: radio stations of operator-controlled vessels; coastal stations; rescue coordination center radio stations; radio disturbances. Main Characteristics GM TRAINER 6.0 simulator incorporates the following simulated features: Radio wave passage using a simplified radio channel model, considering time of day, calendar season, and distance between stations; Offshore GMDSS A1, A2, A3 and A4 radio communications for various global navigation areas; The names, call signs, identification numbers, coordinates, service types, and frequencies used by the coast stations and coast earth stations modeled in the simulator, match the parameters of real stations. The simulated operational areas correspond to the real operational areas. Messaging between an SES Inmarsat workstation, listener and subscribers of shore-based Internet / e-mail networks, telex, and public telephone networks using a fax machine (at least 8 subscribers for each network); Ship-to-shore transmission of distress alerts using an Inmarsat CES listener workstation and shore-to-ship transmission in automatic mode; Transmitting SES Inmarsat messages with “urgency” and “security” categories using two-digit access codes to the listener workstation; The presence of background noise in the telephone mode;
