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

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
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
Transitioning from Ku- to Ka-band

Future HTS DevelopmentsDemand drivers
quest for more throughput....the Netflix effect.....
Fast, cheap, goodPick any two.....
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
23
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
