Enhanced Group Call (EGC)
EGC The EGC services were developed by Inmarsat to achieve access to a unique global automatic service, capable of addressing traffic to predetermined group of ships, or ships in both fixed and variable geographical areas. It can offer automatic services in coastal waters where it may not be possible to establish the NAVTEX service.
Two EGC services The SafetyNET Service The FleetNET Service
The SafetyNET Service This service allows an Information Provider, such as a meteorological or hydrographic office, to broadcast MSI addressed to all, or selected SES within an ocean region.
The FleetNET Service This service is a commercial service and allows an Information Provider such as shipping companies or governments to broadcast information such as company news, or government information to selected SES belonging to a closed network.
Basic concepts of the EGC system
SafetyNET broadcast messages = Coastal warnings ( areas where NAVTEX MSI is not provided ) = Navigational Warnings = Meteorological Warnings = Ice Reports = Search and Rescue information = Meteorological Forecasts = Pilot Service Messages = DECCA; LORAN; OMEGA; and SATNAV system Messages = Other Electronic Navaid Messages = Additional Navigational warnings = Meteorological and Navarea Warnings and meteorological forecasts to ships within specified NAVAREA/METAREA = SAR coordination to fixed or specified circular areas = Shore-to-ship distress alerts to ships w/in specified circular areas = Urgency and Safety messages to ships w/in specified rectangular areas = Chart correction services

What messages you MUST receive Shore-to-ship distress alert for the current NAVAREA; Navigational warnings for the current NAVAREA; Meteorological warnings for the current METAREA.
What messages you MAY receive Meteorological forecasts; MSI for any other NAVAREAs in which the ship is expected to sail.
Good Operating Practice Ensure any equipment associated with the EGC receiver is working properly. Make sure that the terminal is not storing unwanted messages, and has storage space for new messages. Make sure that the terminal is regularly updated with ship’s current position. While in port, keep the EGC receiver in operation, to ensure that you have received all necessary MSI before sailing. At the scheduled time, make sure that the receiver is tuned to the appropriate NCS channel/Ocean Region as given in the current “List of Radio Signals” Throughout your voyage, ensure that a written log is kept of the identities of all received messages, and a printed copy is kept of all distress traffic. Other messages should be kept on the bridge for as long as they remain in force.
