Intelsat V F-1 (or Intelsat 501) was a geostationary communications satellite built by Ford Aerospace, it was owned by COMSAT. Launched in 1981, it was the second of fifteen satellites to be launched. The satellite was based on the platform and its estimated useful life was seven years.

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. The payload housed 21 C-band and 4 Ku-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[]

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