FleetBroadband - a sea of global satellite communication system that provides wideband Internet access, telephony, and SMS and the ISDN network for ocean-going vessels through the portable dome antennas. These antennas size of 291 × 275 mm (FB150) to 605 mm x 630 mm (FB500), a compound capable of providing up to 432 kbit / s. All FleetBroadband antennas operate in the line of sight of one of geostationary orbiting satellites.
Broadband is available in three fourth-generation satellite with a lifespan of at least up to 2020, which received its name in line with areas of action: 1-4 Americas (North, Central and South America), 1-4 EMEA (Europe. Middle East and Africa) and 1-4 Asia-Pacific (Asia Pacific) with surrounding ocean areas.
INMARSAT -As, C,-M,-M -Mini, -F33, -F55 -F77 and work through the other four satellites of the third generation: AOR-E (Atlantic ocean east area), AOR-W (Atlantic ocean west district), IOR (Indian ocean Region) and POR (Pacific region). Service area of all satellites cover areas between about 76 ° north and south latitude at an elevation angle of 5 'above the horizon. In practice it turns out that the maximum latitude up to 80', so that the system can be used FleetBroadband and ice fleet.
