The Inmarsat-B igital mobile satcoms system provides two-way direct-dial phone, fax,
telex and data communications at rates up to 9.6kbit/sec to and from anywhere in the world with the exception of the polar regions.
An Inmarsat B terminal is a small self-contained satellite earth station comprising, in the maritime environment, of an above deck equipment containing a parabolic antenna and electronics and a below deck equipment containing electronic units, power supplies and interface connections. Connections to telex, telephone, modem and facsimile equipment are contained in the below deck equipment.
A call from a Mobile Earth Stations (MES) is routed via the Inmarsat network to a Land Earth Station (LES) and thence into the national and international phone, telex and data networks. There are four Ocean Regions covering the world each with its own operational satellite.
Transmission and reception of signals are co-ordinated by four network co-ordination stations (NCS), one for each ocean region:
- Atlantic Ocean Region East (AORE)
- Atlantic Ocean Region West (AORW)
- Indian Ocean Region (IOR)
- Pacific Ocean Region (POR)
Each NCS monitors the flow of communications traffic through its satellite to ensure that calls are correctly set-up and that all LESs are working correctly.
Otesat-Maritel is offering Inmarsat-B services via «Thermopylae» and hosting Land Earth Stations with the access code "005" for all ocean regions.
