Intelsat VA F-15 or Intelsat 515, then named Columbia 515, was a communications satellite operated by Intelsat and which was later sold to Columbia Communications Corporation. Launched in 1989, it was the fifteenth 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-15 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network, from an orbital station at 60.0° East.

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 29 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.[1]

Launch

The satellite was successfully launched into space on 27 January 1989, at 01:21:00 UTC, by means of an Ariane 2 vehicle from the Crentre Spatial Guyanais, Kourou, French Guiana. It had a launch mass of 1981 kg.[4]

Columbia 515

From 1 April 1998, the satellite is used by Columbia Communications Corporation and renamed Columbia 515. The Ku-band payload will not be used anymore. Columbia Communications was granted by FCC to operate a C-Band satellite as a replacement at this location, 37.8° West. The satellite was deactivated in November 2002.
