  2. Maritime Communication, pp. 47-48 (1-18) • Communication between ships. • Internal communication on the ship. • The category of the message (distress alert, urgency, safety, routine) • DISTRESS ALERT: When there is serious and immediate danger for the vessel, crew and passengers. • URGENCY: When there is serious danger for the vessel, crew and passengers. • SAFETY: When there is imminent risk for navigation. • ROUTINE: is transmitted to ensure safe navigation. • Is a part of SOLAS. Main objective: to prevent accidents by providing MSI and minimize consequences of marine accidents by means of effective communication.

  3. Maritime Communication, pp. 47-48 (1-18) • GMDSS communication equipment: • Sea Area A1: short-range radio services (VHF) – radiotelephony, DSC. • Sea Area A2: medium-range services (MF) – radiotelephony, DSC (+ equipment for Sea Area A1). • Sea Area A3: Inmarsat A, B or C ship/earth station or DSC-equipped HF (high frequency) radiotelephone/telex (+ equipment for Sea Areas A1 and A2). • Sea Area A4 (polar regions): DSC-equipped HF radiotelephone/telex (+ equipment for Sea Areas A1 and A2). No Inmarsat but COSPAS-SARSAT coverage.

  6. Maritime Communication, pp. 47-48 (1-18) • Those that do not need to be fitted with GMDSS equipment (small vessels, not self-propelled vessels, men-of-war). • Terrestrial GMDSS system: RTF (radiotelephony), DSC (Digital Selective Calling), DPT (Direct Printing Telegraphy), NAVTEX (Navigational Telex), SART (Search and Rescue Radar Transponder). • Sattelite GMDSS system: Inmarsat, COSPAS/SARSAT, EPIRB (Emergency Position Indicating Radio Beacons), STAREC (Status-recording System). • Simplex: speaking and listening cannot be done at the same time (“over”); Duplex: speaking and listening can be done at the same time.
