It was ordered to replace the
JCSAT-11
satellite which was lost in a launch failure on a
Proton-M
/
Briz-M
rocket in 2007, and is currently used as an
on-orbit spare
satellite; a role in which it replaced the older
JCSAT-R
spacecraft, providing a reserve for if one of the company's other satellites fails. It is a 4,000-kilogram (8,800 lb) satellite, which was constructed by
Lockheed Martin
based on the
A2100AX
satellite bus
, with the same configuration as
JCSAT-10
and JCSAT-11.
[2]
The contract to build JCSAT-12 was awarded on 6 September 2007, the day after JCSAT-11 failed to reach orbit.
[3]
It was launched, along with the Australian
Optus D3
satellite, by
Arianespace
.
[4]
An
Ariane 5ECA
rocket was used for the launch, which occurred from
ELA-3
at the
Guiana Space Centre
in
Kourou
,
French Guiana
. The launch took place at 22:09 GMT on 21 August 2009, at the start of a 60-minute
launch window
.
JCSAT-12 separated from its carrier rocket into a
geosynchronous transfer orbit
, from which raise itself to
geostationary orbit
using a
LEROS-1C
apogee motor
. It has a design life of fifteen years, and carries forty two
transponders
; twelve G/H band, and thirty J band (US IEEE C and Ku bands respectively).
