JCSAT-5A or N-STAR d, known as JCSAT-9 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.
Satellite description
The spacecraft was designed and manufactured by Lockheed Martin on the A2100-AX 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-AX platform, it uses a 460 N (100 lbf) LEROS-1C liquid apogee engine (LAE) for orbit raising. Its solar panels span 26.9 m (88 ft) when fully deployed, and, with its antennas in fully extended configurations it is 14.3 m (47 ft) wide.
Its payload consists 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, a C-band of 45 watts, and a S beam of 130 watts.
History
On 30 April 2003, JSAT awarded an order for JCSAT-9 to Lockheed Martin and its A2100-AXS platform. Moreover in May 2003, JSAT leased some transponders to NTT DoCoMo to be used as N-STAR d for its WIDESTAR II service. A hybrid satellite with 20 C-band, 20 Ku-band, and 1 S-band transponders, it was expected to launch in 2005 for the 132° East slot.
On 12 April 2006 at 23:29:59 UTC, a Zenit-3SL launching from the offshore Odyssey launch platform successfully orbited JCSAT-9. Separation from the launch vehicle occurred at 00:38:02 UTC. 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 JCSAT-5A and N-STAR d.
