1 Inmarsat - Products and Strategy
Workshop on Satellite in IP and Multimedia Gene Jilg, Chief Technology Officer

2 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

3 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)

4 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) R-BGAN has just completed acceptance testing, and is currently undergoing pre-operational trials and operator training. It is operated out of the Fucino earth station facility in Italy. The air interface has been developed and standardised with both ETSI and TIA, and draws heavily from GSM but with specific enhancements for operation over a satellite channel. This optimisation affects the lower protocol layers, with the upper protocol layers being extremely similar to GSM allowing the integration of current and future GSM services (such as SMS for example). This is a real R-BGAN user terminal, not a demonstration mock up, to give you an idea of the terminal size required to support up to 144 kbps operation. If anyone would like to see a live demonstration of the R-BGAN service, please see me at the end and I can arrange for this at Inmarsat HQ in the next couple of weeks.

5 Regional BGAN Coverage Map

6 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

7 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 The BGAN service will improve on the performance of R-BGAN when it comes into service in 2004. This will add ground segment diversity, voice services, wider coverage and higher data rates. Additional user terminals will also be introduced (smaller and larger than the laptop size used by R-BGAN). Key to the performance of the system is a 9 metre deployed reflector antenna on the satellite capable of generating 1 degree spot beams at L-band, and the advanced DSP based payload and digital beam forming. Channels are switched between beams in multiples of 200 kHz, giving extremely high flexibility to focus resources in specific regions. Extensive frequency re-use is deployed to maximise capacity.

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

9 L-band Beam Patterns These bean plots should give you an idea of the type of coverage offered by BGAN. The map on the left shows an example deployment of the 1 degree Personal Mobile Cell (PMC) beams used to service the small BGAN terminals. Each beam is serviced by an integer number of 200 kHz channels, which are shared by the users present in the beam. As loading increases in a beam, additional channels are allocated to it dynamically. Not all beams are active at any time: some have no channels allocated at all. Procedures for ‘dark beam activation’ are supported by the system, to cover the first user to request service in any specific beam. The map on the right shows larger beams which are used to support Inmarsat’s Existing and Evolved services.
