Inmarsat C system configuration<br />
The Inmarsat C system consists of the Operation Control Center (OCC), Satellite<br />
Control Centers (SCC), Network Coordination Stations (NCS), Land Earth<br />
Stations (LES) and Mobile Earth Stations (MES). The OCC, located at Inmarsat’s<br />
London headquarters, coordinates a wide range of activities in the Inmarsat<br />
system, including commissioning of mobile earth stations.<br />
The Inmarsat C system divides the world into four regions and each region is<br />
covered by its own satellite.<br />
Inmarsat system satellites<br />
Region Satellite Satellite Position<br />
AOR-West Inmarsat 3, F4 54.0°W<br />
AOR-East Inmarsat 3, F2 <strong>15</strong>.5°W<br />
IOR Inmarsat 3, F1 64.0°E<br />
POR Inmarsat 3, F3 178.0°E<br />
In each region there is one NCS and several LESs. The NCS keeps track of all<br />
Inmarsat C transceivers in its region and broadcasts information such as<br />
navigational warnings, weather reports and news. The LESs provide the link<br />
between the MES and the terrestrial telecommunications networks via satellite.<br />
