Superbird-A, also identified as Superbird-1 before launch, was a
It was ordered in 1985 along Superbird-B, Superbird-A1 and Superbird-B1 on the very first order of the SSL 1300 platform.[6][7][8][5] It was also the first satellite of SCC and the second commercial satellite of Japan after JCSAT-1.[5] It was used for video distribution, news gathering, remote publishing and high definition TV service to the main islands of Japan and Okinawa.[1]
Satellite description
The spacecraft was the first satellite designed and manufactured by
It had a launch mass of 2,489 kg (5,487 lb) and a 10-year design life.[1] When stowed for launch, its dimensions were 2.41 m × 2.58 m × 2.20 m (7 ft 11 in × 8 ft 6 in × 7 ft 3 in). With its solar panels fully extended it spanned 20.3 m (67 ft). Its power system generated approximately 3,984 watts of power due to two wings with three solar panels each.[5][1] It also a NiH2 battery to survive the solar eclipses. It would serve as the main satellite on the 158° East longitude position of the Superbird.[5][1]
Its propulsion system included an R-4D-11 liquid apogee engine (LAE) with a thrust of 490 N (110 lbf).[5] It included enough propellant for orbit circularization and 10 years of operation.[5]
Its payload is composed of 23 Ku-band, 3 Ka-band, plus 2 X-band transponders.[5]
History
Space Communications Corporation (SCC) was founded in 1985, the same year as the original companies that later formed JSAT.
