Hellas Sat 2 was launched by a Atlas V rocket from Cape Canaveral Air Force Station, Florida, United States, at 22:10 UTC on May 13, 2003.[5]
Capacity and coverage
The 3.45 tonne satellite carries 30 Ku band transponders to provide direct-to-home voice and video transmissions to much of Europe, North Africa and the Middle East, after parking over 39 degrees east longitude. Also provided television broadcasting services for the 2004 Summer Olympic Games in Athens, Greece.[5]
