JCSAT-110, also known as N-SAT 110, JCSAT-7, Superbird-5 and Superbird-D, is a Japanese geostationary communications satellite which was operated by JSAT Corporation and Space Communications Corporation until both companies merged into SKY Perfect JSAT Group in 2008. It is positioned in geostationary orbit at a longitude of 110° East, from where it is used to provide communications services to Japan. [2] [3] [4]
The spacecraft was designed and manufactured by Lockheed Martin on the A2100-AX satellite bus. It had a launch mass of 3,531 kg (7,785 lb) with a dry mass of 1,669 kg (3,680 lb) and a 13-year design life. 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.
When stowed for launch, the satellite was 6 m (20 ft) high. Its dual wing solar panels gave a power generation capability of 8.3 kW at the end of its design life, with a span of 26.4 m (87 ft) when deployed. [5] [6] With antennas deployed, its width was 8.3 m (27 ft). [2]
Its payload is composed of twenty-four 36 MHz Ku-band transponders with a TWTA output power of 120 watts per channel. With its total bandwidth of 864 GHz, it is used primarily for multi-channel pay per view business. [7] [5] [8]
In September 1997, both JCSAT and Space Communications Corporation (SCC) had requested the 110° East position. [9] The Japanese government made both companies share the 110° East position, and thus they both made a joint order on 20 November 1998 for N-SAT 110 from Lockheed Martin. [9] [10] JCSAT used the JCSAT-7 designation for this satellite, while SCC used Superbird-5. [5]
On 6 October 2000 at 23:00 UTC, an Ariane-42L H10-3 successfully launched N-SAT 110 to a geostationary transfer orbit from Centre Spatial Guyanais ELA-2. [11] One hour later, at 00:04 UTC, on 7 October 2000, the first signals from the satellite were successfully received from the Australia ground station. [12] On 14 October 2000, at around 03:00 UTC, N-SAT 110 reached the geostationary orbit. [13] Once it was put into orbit, it was renamed as JCSAT-110 by JCSAT and Superbird-D by SCC. [5]
On 1 October 2008, JSAT Corporation and Space Communications Corporation merged into SKY Perfect JSAT Group, and the satellite was known simply as JCSAT-110. [7]
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.
JSAT Corporation (JSAT) was the first private Japanese satellite operator, which owned the JSAT satellites, as well as operated and partially owned the N-Star with NTT DoCoMo. Its origins can be traced to the funding of Japan Communications Satellite Company (JCSAT) and Satellite Japan Corporation in 1985. Both companies merged into Japan Satellite Systems Inc. in 1993. In 2000 the company was renamed as JSAT Corporation and was listed in the First Section of the Tokyo Stock Exchange. On September 1, 2008, the company was merged into the SKY Perfect JSAT Group.
JCSAT-11, was a geostationary communications satellite ordered by JSAT Corporation which was designed and manufactured by Lockheed Martin on the A2100 platform. The satellite was designated to be used as an on-orbit, but was lost on launch failure.
The Broadcasting Satellite System Corporation (B-SAT) is a Japanese corporation established in April 1993 to procure, manage and lease transponders on communications satellites. Its largest stockholder, owning 49.9%, is NHK, the Japan Broadcasting Corporation. In 1994, it was ranked by Space News as the world's 19th largest fixed satellite operator.
The SKY Perfect JSAT Group is a Japanese corporate group that claims to be Asia's largest satellite communication and multi-channel pay TV company. It owns the SKY PerfecTV! satellite broadcasting service and the SKY Perfect Well Think content studio, among other businesses.
Superbird-C2, known as Superbird-7 before launch, is a geostationary communications satellite operated by JSAT Corporation and designed and manufactured by Mitsubishi Electric on the DS2000 satellite bus. It had a launch weight of 4,820 kg (10,630 lb), a 15-year design life and was the first commercial communications satellite built in Japan. Its payload is composed of 28 Ku-band transponders with a total bandwidth of 828 MHz.
Superbird-B2, also known by its pre-launch designation Superbird-4, is a Japanese communications satellite which is operated by SKY Perfect JSAT Group. It was originally built and launched for the Space Communications Corporation (SCC), which merged with JSAT Corporation (JSAT) in October 2008. It was constructed by Hughes Space and Communications and is based on the HS-601 HP satellite bus.
Superbird-A, also identified as Superbird-1 before launch, was a geostationary communications satellite designed and manufactured by Ford Aerospace) on the SSL 1300 satellite bus. It was originally ordered by Space Communications Corporation (SCC), which later merged into the SKY Perfect JSAT Group. It had a mixed Ku-band, Ka-band and X-band payload and operated on the 158° East longitude.
JCSAT-RA, previously known as JCSAT-12, is a Japanese geostationary communications satellite, which is operated by SKY Perfect JSAT Group.
