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. As most satellites based on the A2100 platform, it uses a 460 N (100 lbf) LEROS-1C LAE for orbit raising. 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.
Its payload is composed of eighteen 27MHz and twelve 36MHz Ku band plus twelve C band transponders, for a total bandwidth of 1,350 MHz. Its high power amplifiers had an output power of 127 Watts on Ku band and 48 Watts on C band.
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.
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.
