INMARSAT C SYSTEM OVERVIEW
Introduction
The Inmarsat C system provides worldwide telex and data transmission and
reception of written information to owners of an Inmarsat C transceiver or a
terrestrial telex network via satellite. Further, e-mail can be sent via the internet.
Communication mode is store-and-forward telex, which means all information
sent are first stored at an LES and then delivered to designated party.
An EGC (Enhanced Group Call) receiver is built in the FELCOM 15 to receive
the following types of messages, broadcast by LESs:
•
SafetyNET
TM
-governments and maritime authorities can use this service to
distribute maritime safety information to ships within selected areas.
•
FleetNET
TM
-commercial subscription organizations or shipping companies
can use this service to transmit trade information (for example, company
news or market prices) simultaneously to a selected group of ships, to
provide up-to-the-minute information.
•
EGC system-related is sent by Inmarsat to certain shipping companies and
geographical areas.
FELCOM 15 allows you to make distress calls. They are given immediate priority
over all other calls, and are automatically routed to a land-based
Rescue
Co-ordination Centre (RCC)
.
Besides its primary application of ship-shore, shore-ship or ship-ship
communications, the Inmarsat C service has also proved beneficial to trucking
firms who have found it indispensable for communicating with their vehicles. In
this manual, however, we will concentrate on ship applications, the main
application.
