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

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)

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

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
