OVERAGE
Inmarsat operates four, strategically placed geostationary satellites. Each satellite is
located over and named after an oceanic region. The four satellite ocean regions are:
Atlantic Ocean Region-East (AOR-E)
Atlantic Ocean Region-West (AOR-W)
Indian Ocean Region (IOR)
Pacific Ocean Region (POR)
The diagram below represents the satellite ocean regions with approximate transfer
coordinates for satellite transitions.
The four satellite ocean regions are made up of smaller, spot-beam coverage areas. The
following maps show the Inmarsat satellite spot-beam coverage for the four ocean
regions—as well as a composite map of the four regions combined.
