Inmarsat's major satellite constellation consists of 4 Inmarsat-3 satellites in geostationary orbit. Involving them, the main ("global") beams from the satellites present overlapping coverage in the complete surface on the Earth apart from the poles. So, thanks to Inmarsat, it is becoming doable to extend the reach of terrestrial wired and cellular networks to virtually anyplace on Earth.

A geostationary satellite television follows a circular orbit in the plane on the Equator at a height of 35,600km, in order that it seems to hover over a chosen place within the Earth's area. Three this sort of satellites are enough to cover most with the globe, and cellular users rarely must switch from just one satellite television to another. Other cellular satellite techniques use greater numbers of satellites in lower, non-geostationary orbits. In the user's place of view, they move across the sky with a comparatively substantial speed, often requiring a switch from one particular satellite to an additional in the middle of-communication and risking the opportunity of an interrupted call.

A call from an Inmarsat cellular terminal goes directly towards satellite overhead, which routes it back down with a gateway on the ground referred to as a land earth station (LES). From there the call is passed into the public mobile phone network.

The Inmarsat-3 satellites are backed up by a fifth Inmarsat-3 and four previous-generation Inmarsat-2s, also in geostationary orbit.

A crucial edge in the Inmarsat-3s around their predecessors is their ability to produce a number of spot-beams at the same time as solitary large worldwide beams. Spot-beams concentrate added energy in locations of high demand likewise as making it achievable to provide standard providers to smaller, simpler terminals.

Inmarasat is often a consortium of leading global telecommunications firms originally established in 1991. The Inmarasat system is made to provide large excellent satellite-based services to some broad array of customers, which includes:

* Voice calling * Short Messaging Support (SMS) * Roaming * Positioning * Facsimile * Data transmission
