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.


The SafetyNET Service

The FleetNET 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.


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.
