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 may 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 16 to receive the following types of messages, broadcast by LESs:

•SafetyNETTM-governments and maritime authorities can use this service to distribute maritime safety information to ships within selected areas.

•FleetNETTM-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.

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.
