The Star One C3 satellite being manufactured for Star One S.A. will carry a hybrid payload. 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.
