INMARSAT C SYSTEM

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.
Communication mode is store-and-forward telex, which means all information
sent are first stored at a LES and then delivered to designated party.
An EGC (Enhanced Group Call) receiver is built in the FELCOM to receive the
following types of messages, broadcasts from a LES:
• SafetyNET
distribute maritime safety information to ships within selected areas.
• FleetNET
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.
FELCOM 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.
