GX Aviation Vs other providers
George NicolaAviation Technical Marketing Manager
Inmarsat – global, mobile, reliableMobile and fixed networks are fundamentally different!
Pacific OceanWarkworth and Auckland (NZ)
Indian OceanFucino (IT) and Nemea (GR)
Atlantic OceanLino Lakes (US) and
Winnipeg (CA)
Power optimised for coverage
Power focused over specific markets
Spot beam architecture with Frequencyre-use to maximize efficiency
Wide beams used for broadcast areas – no frequency re-use essential for other applications
Reliable and robust links for the users with diversity
Satellite networks lease transponder bandwidth to providers
Seamless handovers with mobility protocols
Mobility is not a primary goal
Next generation Ku-band
Intelsat EPIC (IS-29e) platform operates spot beams in specific regions with wide beams covering other sectors
• High power in limited regions
• Low power in others
Level of service available varies from spot beam to wide beam
Currently IS-29e is under construction (expected mid 2015), IS-33e is now on order (expected mid 2016)
Remaining coverage has low performance compared to GX Aviation
Intelsat EPIC available only in a very limited coverage area for HTS

So what is the result?
Existing Ku-band satellites
Wide beams used to provide coverage with satellite networks optimised for broadcast services
Power level of wide beams vary across the footprint with power falling off as you approach edge of coverage
Next generation Ku-band satellites
Moving over to spot beams for frequency re-use and increase in bandwidth
Will provide improvements but only in certain regions
Ultimately the transponder lease model will continue and mobile operators in the band will be forced to deliver coverage formed by a “patchwork” mobile network
Different satellites from different providers means a mix of varying capabilities and non-uniform performance
More frequent satellite handovers and service interruptions for the users
But what about other Ka providers?
