JCSAT-10 (Apr 2004 to Aug 2006)
JCSAT-3A, known as JCSAT-10 before launch, is a geostationary communications satellite operated by SKY Perfect JSAT Group (JSAT) which was designed and manufactured by Lockheed Martin on the A2100 platform.
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.
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.
