What services are available through Enhanced Group Calls?

Correct Answer: Option A — Maritime Safety Information and messages to pre-defined groups of subscribers.

SafetyNET, the EGC service, provides both Maritime Safety Information (MSI) and FleetNET services for commercial or administrative messages to pre-defined groups. It is a dual-purpose system integrated into the GMDSS to ensure that both safety-critical and operational information reaches the intended vessels efficiently via the Inmarsat satellite network.
