High Throughput Satellites Not all created equally

0 50 100 150 200 250 300

Anik F2 - 2004IPStar - 2005

WildBlue 1 - 2006Spaceway 3 - 2007

KASAT - 2010ViaSat 1 - 2011

Juipiter 1 - 2012Imarsat 5-F1 (GX) - 2013

Intesat 29e - 2016Jupiter 2 - 2017ViaSat-2 - 2018

Estimated Throughput (Gbps)

Broad Beam Replacements Incumbent’s Strategy

• Incremental Improvements • Multi-mission payloads • Open Systems

Intelsat Epic (29e ku-band coverage shown)

Eutelsat 172b (ka-band coverage shown) 3

Global Coverage Augmentation Coverage over Throughput

• Protect Existing Businesses served by Global L-band network

• Emphasis on Coverage, not Capacity • Establish Ecosystem

• Equipment providers • Sales and distribution

Inmarsat GX Constellation 89 fixed & 6 steerable ka-band spot beams

4

Regional Disruptors Capacity over Coverage • Emphasis on Bandwidth Economics • Address Consumer Market • Disrupt Satellite Incumbents

KASAT 82 Ka-band spot beams

ViaSat-1 72 Ka-band spot beams 5

LEO & MEO Constellations Redux • OneWeb, SpaceX, 03b, Others

• 10s to 100s to 1000s of satellites

• Uniform (Global) Coverage

• Lower Latency

• Technology Refresh

• But…70% of the world’s surface is covered by water

6

Future Trends Terabit Satellites

Improve Economics • Bigger payloads • More, smaller spots • More spectrum

Coverage Flexibility • Demand isn’t uniform • Put the capacity where it’s needed

Global to Address Many Markets • Residential • Enterprise • Aeronautical • Maritime • Government
