Intelsat V F-1 (orIntelsat 501) was ageostationary communications satellite built byFord Aerospace, it was owned byCOMSAT. Launched in 1981, it was the second of fifteenIntelsat V satellites to be launched. The satellite was based on theIntelsat V platform and its estimated useful life was seven years.

Satellite

[edit]

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 bynickel-hydrogen batteries duringeclipse, provided 1800 watts of power. The payload housed 21C-band and 4Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It had a launch mass of 1928 kg.^[3] The satellite was deactivated in February 1997.

Launch

[edit]

The satellite was successfully launched into space on 23 May 1981, at 22:42:00 UTC, by means of anAtlas SLV-3D Centaur vehicle from theCCAFS,LC-36B.^[4]
