Inmarsat - Products and Strategy

Workshop on Satellite in IP and Multimedia

Gene Jilg, Chief Technology Officer 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

2 Current Portfolio of Services Circuit switched: – Inmarsat-A: tel, fax, 64 kbit/s data – Inmarsat-B (digital replacement to A) – Inmarsat-M/mini-M: tel., fax, 2.4 kbit/s data • Inmarsat Aero miniM – Inmarsat Aero I / H: tel., fax, 2.4 / 4.8 kbit/s data – Inmarsat GAN ISDN: tel, fax, ISDN (64 kb/s 1B+S) – Fleet 77/Swift 64 : tel, fax, ISDN

Messaging/ Packet based, data services: • Inmarsat-C: low bit rate S/F messaging • Inmarsat Aero C • Inmarsat-D/D+: two way paging system • Inmarsat Aero L / H: 0.6 / 10.5 kbit/s packet data (X.25) • Inmarsat E: distress alert service for maritime • Inmarsat GAN MPDS: 64kb/s packet data over shared bearer • Fleet 77 (MPDS)

3 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)

5 Regional BGAN Terminal

User terminal looks and feels like a laptop, costs about $1100, receives and transmits at 144 kbps with end-user airtime charge around $11/MByte

6 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

7 Inmarsat-4

• User Link : L Band • Feeder Link : C Band • Processed Band : 2 x 126 MHz • Spacecraft Power : 12 kW • Launch Mass : 6 Tons • Solar Array Span : 48 m • Prime Contractor : Astrium • Major Subcontractors – TRW Astro, L Band Reflector – EMS, L Band Feed • Launchers – Atlas V – Ariane 5
