JCSAT-2A, known asJCSAT-8 before launch, is ageostationarycommunications satellite operated bySKY Perfect JSAT Group (JSAT) which was designed and manufactured byBoeing Satellite Systems on theBSS-601 platform. It hasKu-band andC-band payload and was used to replaceJCSAT-2 at the 154° East longitude. It covers Japan,East Asia, Australia andHawaii.[2][3][4]
The spacecraft was designed and manufactured byBoeing Satellite Systems on theBSS-601satellite bus. It had a launch mass of 2,460 kg (5,420 lb) a power production of 3.7 kW and an 11-year design life.[2] Stowed for launch it measured 3.6 m × 2.7 m × 4.3 m (11.8 ft × 8.9 ft × 14.1 ft), with itssolar panels and antennas deployed it measured 21 m × 4.3 m × 7.6 m (69 ft × 14 ft × 25 ft).[4][5]
Its payload is composed of sixteen 57 MHz Ku-band plus eleven 36 MHz and five 54 MHz C-bandtransponders, for a total bandwidth of 1,578MHz.[6] Itshigh-power amplifiers had an output power of 120watts on Ku-band and 34 watts on C-band.[4][5]
The Ku-bandfootprint covers only Japan, while the C-band beams cover Japan, East Asia, Australia and Hawaii.[4]
In April 2000, JSAT orderedJCSAT-8 fromBoeing (which had acquired theHS-601 business fromHughes), to replaceJCSAT-2 at the 154° East slot. It would provide coverage to Japan, East Asia, Australia and Hawaii.[2]
AnAriane 44L successfully launched JCSAT-8 on 29 March 2002 at 01:29UTC fromCentre Spatial Guyanais. Once successfully deployed, it was renamedJCSAT-2A.[2]
