Classic Services Overview ACARS (DATA-2) AES X.25 (DATA-3) Cabin and Cockpit voice and data services with full P3 capability PSTN GES

Inmarsat Aero-H Global Beam Only 21K Voice PC-data and Fax Packet Data 600 – 10500 bps channel rates Shared channels

Inmarsat Aero-I/H+ Aero-I (Intermediate Gain Antenna) Spot Beam Operation 8.4K Voice PC-data and Fax Global Beam Operation Packet Data at 600 – 4800 bps Aero-H+ (High Gain Antenna) Global & Spot Beam Operation Packet Data at 600 to 10500 bps

Inmarsat-3 Spotbeam Coverage Area

Inmarsat Aero-L Global beam only Low Gain antenna – Omnidirectional Data 600 and 1200 bps Supported by all GESs

Inmarsat Swift64 Uses existing High Gain Antenna Has two services Swift64 ISDN Service Swift64 MPD Service Uses existing Inmarsat ISDN and MPDS infrastructure on INM-3 spotbeams Swift64 ISDN Swift64 MPDS

Swift64 ISDN Service AES NCS LES ISDN

Swift64 ISDN Service Circuit mode service One ‘user’ per channel Data throughput is 64 kbits/s Charged per time unit

Swift64 MPD Service User AES Internet Internet NCS HLES SBS

Swift64 MPD Service Packet mode service. Multiple ‘users’ per channel. User has a portion of the 64 kbits/s channel at any one time. Charged per kbit not connection time.

Aeronautical BGAN Swift64 Inmarsat-4 satellites will provide new service opportunities in all aeronautical market segments: Increase data rates for existing satcoms installations. New data services for medium/ short-haul aircraft and helicopters.
