Intelsat VA F-12, then named Intelsat 512, was a communications satellite operated by Intelsat. Launched in September 1985, it was the twelfth of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat VA satellite bus. Intelsat VA F-12 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network.

Satellite

The satellite was box-shaped, measuring 1.66 by 2.1 by 1.77 metres; solar arrays spanned 15.9 metres tip to tip. The arrays, supplemented by nickel-hydrogen batteries during eclipse, provided 1800 watts of power at mission onset, approximately 1280 watts at the end of its seven-year design life. The payload housed 26 C-band and 6 Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It also provided maritime communications for ships at sea.

Launch

The satellite was successfully launched into space on 29 September 1985, at 23:36:00 UTC, by means of an Atlas G-Centaur D1AR vehicle from the Cape Canaveral Air Force Station, Florida, United States. It had a launch mass of 1981 kg. The satellite was deactivated in July 1998.
