Overview of Inmarsat Today
• Leading global mobile satellite communications service provider– Data and voice to maritime, land and aeronautical users– 23 years of market, technical and regulatory experience
• Established in 1979 as an international co-operative• Service on leased satellites beginning in 1982• Satellite operator since 1990• Privatised as a United Kingdom entity in April 1999
– 9 successful satellite launches (Inmarsat-2 and Inmarsat-3 fleets); all satellites still fully operational
– More than 260,000 registered terminals

Regional BGAN
• 144 kbps data services• Via leased capacity on Thuraya satellite• Anchored at a SAS facility in Fucino (Italy)• Air interface based on GSM adapted to satellite usage
– Standardised as GMR-1 by ETSI and TIA enhancing future interoperability
• Migration path to GPRS or UMTS PS service– Strong resemblance to GSM in upper protocol layers
allows integration of standard GSM services (SMS)

BGAN
• Improves upon performance of Regional BGAN– Full ground segment diversity (Holland and Italian SASs)– Voice and data services supported– Higher data rates (up to 432 kbps)– Increased coverage (US, Europe, Far East)
• Two Inmarsat 4 satellites– 53 °W and 64 °E– 9 m L-band satellite antenna – generates 1° spot beams– Flexible DSP based payload, 630 dynamically assigned
channels, digital beam forming– 200 kHz channels
