Data relating to <strong>Flight</strong> <strong>207</strong><br />

The satellite<br />

EchoStar XVII is built by SPACE SYSTEMS/LORAL. It is based on the LS 1300E BUS satellite<br />

platform, which, all satellites taken together, represents a total of more than 1900 years in<br />

orbit.<br />

The launch of EchoStar XVII using JUPITER broadband technology will provide subscribers<br />

with a rate of more than 100 gigabits per second. Its multi-beam architecture will enhance and<br />

reinforce coverage and will target areas of North America where demand is greatest. It will thus<br />

supplement SPACEWAY 3, launched by <strong>Ariane</strong> 5 on 14 August 2007, and which provides<br />

uniform coverage of the USA. EchoStar XVII will provide high-speed internet access to nearly 2<br />

million extra subscribers, offering them unique media access.<br />
