'''Intelsat VA F-11''', then named '''Intelsat 511''', was a [[Astronomy:Communications satellite|communications satellite]] operated by [[Company:Intelsat|Intelsat]]. Launched in 1985, it was the eleventh of fifteen Intelsat V satellites to be launched. The Intelsat VA series was constructed by Ford Aerospace, based on the Intelsat VA [[Engineering:Satellite bus|satellite bus]]. Intelsat VA F-11 was part of an advanced series of satellites designed to provide greater telecommunications capacity for [[Company:Intelsat|Intelsat]]'s global network.

== Satellite ==
The satellite was box-shaped, measuring 1.66 by 2.1 by 1.77 metres; [[Physics:Photovoltaic system|solar arrays]] spanned 15.9 metres tip to tip. The arrays, supplemented by [[Physics:Nickel–hydrogen battery|nickel-hydrogen batteries]] during [[Astronomy:Eclipse|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 [[Astronomy:C band (IEEE)|C-band]] and 6 [[Astronomy:Ku band|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.<ref name="Display">{{cite web |url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1989-006A|title=Display: Intelsat 5A F-15 1989-086A|publisher=NASA|date=14 May 2020|access-date=29 June 2020}} {{PD-notice}}</ref>

== Launch ==
The satellite was successfully launched into space on 30 June 1985, at 00:44:00 UTC, by means of an [[Engineering:Atlas G|Atlas G-Centaur-D1AR]] vehicle from the {{wipe|Cape Canaveral Air Force Station}}, Florida, {{wipe|United States}}. It had a launch mass of 1981&nbsp;kg.<ref name="TBS">{{cite web|url=http://www.tbs-satellite.com/tse/online/sat_intelsat_511.html|title=Intelsat 511|publisher=TSE|access-date=29 June 2020}}</ref> The satellite was deactivated in August 2003.
