7 Europasat (S-band) [Overview of system and summary of EU selection process to be added] Inmarsat and Solaris successful in EC managed European selection process Each operation has access to 2x15 MHz of spectrum May include a complementary ground component (CGC) Inmarsat developing an aeronautical CGC, for provision of passenger connectivity

8 Global Xpress TM US$1.2 billion global broadband network Download speeds of up to 50 Mbps to 60 cm antenna Upload speeds around 5 Mbps for 60 cm antenna Boeing contracted to build four Inmarsat-5 satellites First launch 2013, with global coverage in 2014 Each satellite to carry 89 Ka-band beams Plus steerable spot beam capacity (HCP) Lifetime of 15 years Complements our L-band services 8

9 Global Xpress Spectrum Global payload User Uplink: GHz User Downlink: GHz Feeder Uplink: GHz Feeder Downlink: GHz HCP Payload User Uplink: GHz User Downlink: GHz Feeder Uplink: GHz Feeder Downlink: GHz Why Ka-band? 2.5 GHz of available spectrum 5 times the availability at Ku Includes 2x500 MHz of spectrum exclusive to satellite Fewer operational satellites simplify coordination 9

10 Global Xpress User Terminals Uses adaptive coding and modulation to maintain link in rain-fade Data rates for 60 cm antenna: 5 Mbit/s uplink, 50 Mbit/s downlink for 60 cm Larger and smaller terminals with higher or lower datarates) Maritime Aero Land-based 1m 60cm Class A Class B Fixed Transportable COTM Manpack Antenna Size (cm) x70 30 >100 TBD TBD <70 Antenna Structure reflector reflector asymmetric symmetric reflector reflector asymmetric Flat panel/reflector 10

13 Sector trends L-band GSO systems - steady growth - satellites being replaced - possible use of ATC in North America - continuing need for high reliability (safety) and modest bandwidth applications. L-band and S-band LEO systems - satellites being replaced, will extend life by >15 years - greater emphasis on data over voice Development of S-band in Europe, including CGC Ka-band mobile systems for high bandwidth applications

14 Expected changes to technology and spectrum Driven by demand for mobile broadband, particularly locations hard to reach by terrestrial means Need for higher data rates, and reduced cost per bit to users Leads to increasing efficient use of lower frequency spectrum (e.g. use of: - multi-spotbeam/high gain satellite antenna (22m unfurlable antenna now in operation), - use of complementary ground components Terminal technology allows highly stable mobile platforms (e.g. pointing accuracy within 0.2 deg, on a ship or aircraft)......means small terminals, consistent with conventional FSS VSATs......and that opens up the FSS bands for mobility, in particular the Kaband

15 Longer-term (10-20 years) technology and spectrum needs and options Spectrum aspects: Satellite spectrum must be well harmonised internationally Therefore fully reliant on the ITU frequency allocations and administrations respecting those allocations For mobile satellite use, sharing with terrestrial use is often impractical, and that may require administrations to refrain from authorising terrestrial use in some bands Technology: Expect to see more satellites in Ka-band, and additional frequency bands used for mobility
