1.1.1 Coverage area
The Inmarsat Satellites cover the earth’s surface except at the high latitude areas near the North
Pole and the South Pole.
Inmarsat terminals are available for any type of vehicle or ship, and are capable of communicating
day and night.
The Inmarsat coverage map displays the area of three satellite regions
・Europe, Middle East, Africa (EMEA) Ocean Region
・Asia-Pacific (APAC) Ocean Region
・Americas (AMER)Ocean Region
A geostationary satellite is placed on each Ocean Region (excluded spare satellites).
The adjacent Ocean Regions have overlapped area of satellite regions. Suitable Ocean Region
(satellite region) is automatically selected when JUE-501/JUE-251 positions in overlapped area.
