Inmarsat Satellites

Inmarsat Logo

Inmarsat is a British satellite telecoms company, first privatised in 1999. In 2010 it won the MacRobert Award for its Broadband Global Area Network (BGAN) service.

Inmarsat's latest I4 satellite system (as used for Inmarsat BGAN and Inmarsat FleetBroadband) uses 3 geostationary satellites to provide near global coverage. The previous generation I3 satellites ( Inmarsat Mini M, Inmarsat Fleet 33 Fleet 55 and Fleet 77 systems) used 4 satellites to cover approximately the same area.

Coverage

Coverage is near global for voice and data (i.e. Internet). Note: On the smaller terminals performance will be reduced or unavailable near the fringes of the coverage area.

The advantage of the geostationary satellites is that your satellite phone antenna does not need a clear view of the whole sky, but only a narrow gap pointing directly at the satellite (possibly between two buildings or a gap in the tree canopy).

However, because the satellites are in fixed orbits above the Equator there are some gaps in global coverage. There are two reasons for this:

1) As the Earth curves away from the satellite towards the poles the satellite will appear lower and lower in the sky. This has the affect of increasing the footprint of a single spot beam, meaning that the signal is having to travel further and is less focused.
2) Eventually the curve of the earth will block the satellite from view entirely, resulting in the the gaps in coverage above the north and south poles. (see Inmarsat I4 coverage map opposite)
