High Throughput SatellitesDefinition

Multi-spot beam, multiple frequency re-useSignificantly greater throughput from a given orbital

location compared to traditional FSS designsHTS satellites are not restricted to Ka band

Some of the first HTS satellites operated at Ku band (IPStar) Intelsat EPIC

GEO HTS Regional Global Constellations

MEO HTS ConstellationsLEO HTS Constellations

Closed versus Open SystemsClosed Systems

Purchase managed service (Mbps)Pre-defined standardised service offeringAsymmetric services are typicalRemote terminals standardisedAll traffic must flow through operator’s

gatewaysQoS is pre-defined

Open SystemsCan purchase MHz

Hybrid models also offer managed service optionsOfferings are tailored for specific applicationsThird party gateways are possibleQoS is determined by network configuration

Is HTS a Disruptive Technology?Changing the metrics of the satellite industry

Mbps versus MHzFill-rate – what is the valid measurement?End-to-end solutions Packaged solutions rather than bespoke solutions

Potential to cannibalise existing FSS revenuesViaSat-3 constellation = 2 x total capacity of existing GEO

fleetImpact on service providers and teleport operators

Defined gateway locationsOperator build out of unified networkLimited opportunities for third party teleport operators

HTS System DesignTotal System Throughput is determined by:

Modulation Efficiency

Available Bandwidth

Frequency Re-use

Page 18: Session 2 3 david ball consultant

18

HTS System DesignImproving Total System Throughput:

Modulation Efficiency Gains are limited by channel non-linearity

Available Bandwidth Reduce colour count – wider transponder BW Expansion into non-standard bands, new frequency

bandsFrequency Re-use

Narrower beams, increased spotbeam count, increased frequency re-use

Future HTS DevelopmentsDemand drivers

quest for more throughput....the Netflix effect.....

Fast, cheap, goodPick any two.....

Page 22: Session 2 3 david ball consultant

22

Future HTS Developments – Efficiency Drivers / GoalsIncrease Overall Throughput

Modulation efficiencyUse of new frequency bands for feeder links

Need to consider spectrum licensing and availabilityReduce Cost per Bit

Space segment cost – improve efficiencyGateway efficiency – throughput / number of gatewaysReduce cost of user equipment / antennas / installation

Flexible ArchitectureRespond to changing market demandsIncreased deployment of processing payloads

Page 23: Session 2 3 david ball consultant

Future HTS Developments – Additional SpectrumUse additional feeder link spectrum

Q band Space-to-earth 37.5 – 42.5 GHz

V band Earth-to-space 47.2-51.4 GHz

W band Space-to-earth 71-76 GHz Earth-to-space 81-86 GHz

Most ITU filings already include Q and V bandThe race for spectrum has begun early

Equipment availability limited at this time
