Satellite description
The spacecraft was designed and manufactured by Lockheed Martin on the A2100AX satellite bus. It had a launch mass of 4,401 kg (9,703 lb) and a 12 year design life. It would provide communications services throughout Japan and Asia and for NTT DoCoMo . 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 14.3 m (47 ft) wide.
It's payload is composed of eight 54 MHz and twelve 36 MHz Ku band transponders, twenty 36 MHz C band transponders and one S band beam. The Ku band transponders have a TWTA output power of 110 Watts, the C band of 45 Watts and the S beam of 130Watts.
History
On April 30, 2003 JSAT awarded an order for JCSAT-9 to Lockheed Martin and its A2100AXS platform. And on May 2003 JSAT leased some transponders to NTT DoCoMo to be used as N-STAR d for its WIDESTAR II service. An hybrid satellite with 20 C band, 20 Ku band, and 1 S-band transponders, it was expected for launch in 2005 for the 132° East slot.
On April 12, 2006 at 23:29:59 GMT a Zenit-3SL launching from the offshore Ocean Odyssey launch platform successfully orbited JCSAT-9. Separation from the launch vehicle occurred at 00:38:02 GMT. JSAT had leased some transponders to NTT DoCoMo to be used as N-STAR d. Once in its 132°East orbital position, it was renamed as JCSAT-5A and N-STAR d.
