The satellite, Optus C1, is a third-generation system designed to replace an existing spacecraft in the Optus communications constellation, and to provide additional, enhanced capabilities when it is launched in 2002.

Cable & Wireless Optus, a major Australian telephone and communications company, will use Optus C1 to provide distribution for video, direct-to-home TV, and telephony and Internet connections to remote areas. The area of fixed satellite services coverage includes Australia, New Zealand, and Asia. Optus C1 will also provide communications services for the Australian Defence Forces.

To provide these services, Optus C1, a high-powered model in SS/L's 1300 geostationary satellite bus family, will carry 18 antennas and four payloads: a Ku-band payload for the commercial mission, and UHF, X-, and Ka-band payloads for the defense tasks. Total power on the satellite, designed to operate for 15 years, will be approximately 11kW at end of life. Optus C1 will have a launch mass of nearly five metric tons.

SS/L is responsible for the overall system design, and the design of the satellite bus and will assemble, integrate, and test the satellite. As prime contractor, MELCO will be responsible for the design, manufacture, and test of the payload.

"MELCO and SS/L have an excellent working relationship developed over a span of more than 27 years, beginning with the CS1 satellite, built for Japan's National Space Development Agency, the equivalent of our NASA," said Dr. John M. Klineberg, president of SS/L. "We look forward to the productive continuation of our long-standing affiliation." MELCO and SS/L have cooperated on programs such as: Intelsat 5, 5A, 7/7A, Agila 2, EchoStar, PanAmSat 7 and 8, and Tempo.

According to Dr. Klineberg, the Optus C1, one of the most complex commercial communications satellite projects to date, represents a pioneering example of cooperation on a spacecraft intended for joint commercial-defense use.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005
The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India.
