Description:

• The Star One C3 satellite was ordered from Star One S.A. in March 2010 and will carry a hybrid payload and will be located at an orbital slot between 75 and 84 degrees West Longitude. Based on Orbital’s Enhanced Star-2.4 Bus, the spacecraft will carry 28 active C-band transponders for coverage of South America, and 16 Ku-band transponders with six switchable channels between Brazil and the Andean coverage region. Star One C3 will generate approximately five kilowatts of payload power and will feature two 2.3 meter deployable reflectors and one 1.4 meter earth deck-mounted antenna.
• STAR ONE C3, to be positioned at 75°W or 84°W, will provide direct TV broadcast, telephone and long-distance domestic communications services for Brazil and South America

Mission details:

• Ariane flight VA210 placed two communications satellites in orbit. The vehicle 566 core stage reached a -956 x 179 km x 7.0 deg path; the ESC-A upper stage raised velocity and lowered inclination to reach a 250 x 35750 km x 2.0 deg transfer orbit, deploying the EUTELSAT 21B satellite, a Thales Alenia Spacebus 4000C3 for Eutelsat SA of Paris and Star One C3, an Orbital Geostar-2.4E for Star One of Rio de Janeiro.
• The Star One satellites continue the old Brasilsat system, with Brasilsat B1-B4 renamed Star One B1-B4; AMC 12 is Star One C12; Star One C1 and C2 are Spacebus 3000 class satellites launched in 2007 and 2008.
