Satellite description

The spacecraft was designed and manufactured by Lockheed Martin on the A2100AX satellite bus. It had a launch mass of 4,048 kg (8,924 lb) and a 15-year design life. It would provide communications services throughout Japan and Asia.[4] As most satellites based on the A2100 platform, it uses a 460 N (100 lbf) LEROS-1C LAE for orbit raising.[4] Its solar panels span 26.9 m (88 ft) when fully deployed and, with its antennas in fully extended configuration it is 8.6 m (28 ft) wide.[5]

Its payload is composed of eighteen 27 MHz and twelve 36 MHz Ku band plus twelve C band transponders, for a total bandwidth of 1,350 MHz.[6] Its high power amplifiers had an output power of 127 Watts on Ku band and　48 Watts on C band.[5]

History

On April 20, 2004, JSAT ordered a satellite from Lockheed Martin, JCSAT-10. Based on the A2100AX platform, it would have a C band and Ku band payload and was expected to occupy the 128°East slot after its planned 2006 launch.[7]

On August 11, 2006 an Ariane 5 ECA launched JCSAT-10 along Syracuse-3B into a transfer orbit. Upon successful deployment at 128°East longitude, it was renamed JCSAT-3A.[4]

gollark: It made some sense in the past as some kind of crystallized "no promiscuity" law when we didn't have contraception and stuff.
gollark: In what way?
gollark: 5 is just elder-worship, which I do *not* agree with, no murdering is reasonable but narrow in scope, the adultery one doesn't seem very important or fundamental-law-y, stealing is bad I guess, bearing false witness is somewhat bad too I guess, the coveting ones seem unnecessary.
gollark: I like to hope I would be better than to demand obedience/worship/belief on pain of eternal torture.
gollark: Just looking up the ten commandments quickly, fully two fifths of these are just bizarre narcissistic stuff about God.
