Intelsat VA F-14
, was a
communications satellite
operated by
Intelsat
. Launched in 1986, it was the fourteenth 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-14 was part of an advanced series of satellites designed to provide greater telecommunications capacity for
Intelsat
's global network.

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 31 May 1986, at 00:53:03 UTC, by means of an
Ariane 2
vehicle from the
Centre Spatial Guyanais
,
Kourou
,
French Guiana
. It had a launch mass of 1981 kg.
[4]
During the Ariane 2 maiden flight, the third stage had a partial ignition followed by another ignition above nominal pressure which led to the engine's failure and the destruction of the launcher.
Investigation
[
edit
]
Because the upper stage of the Ariane 2 was shared with the other Ariane rockets, all flights were suspended until 16 September 1987. As a result of an investigation into the ignition irregularities, it was decided that installing more powerful igniters would sufficiently rectify the issue.
