Our coverage
Satellite footprints form seven overlapping regions
Our satellites transmit radio beams that form seven overlapping regions across the globe. Their combined footprint provides seamless worldwide communications coverage, except in the extreme Polar Regions, from latitudes 76 degrees North to 76 South, with limited service (not guaranteed) up to +/-80 degrees.
Beams cover oceans and land masses
As Inmarsat was founded as a maritime communications operator, the first wholly-owned constellations − the Inmarsat-2 and Inmarsat-3 series − are located above the sea to form four ocean regions:
- Atlantic Ocean Region West (AOR-W), at 54 degrees West
- Atlantic Ocean Region East (AOR-E), at 15.5 degrees West
- Indian Ocean Region (IOR), at 64 degrees East
- Pacific Ocean Region (POR), at 178 degrees East.
Following the full deployment of the Inmarsat-4 (I-4) satellite constellation in 2009, a further three satellite regions were created over the Earth's major land masses. They are:
- I-4 Americas, at 98 degrees West
- I-4 EMEA (Europe, Middle East and Africa), at 25 degrees East
- I-4 Asia-Pacific, at 143.5 degrees East.
