JCSAT-17 is a geostationary communications satellite operated by SKY Perfect JSAT Group. The satellite was designed and manufactured by Lockheed Martin Space on the LM-2100 platform, and was launched on 18 February 2020 on an Ariane 5. [3] The satellite mainly provides service to Japan and the surrounding regions. Utilizing several S-band transponders with a flexible processor, the satellite has the capability to redirect communications capacity to concentrate on disaster relief efforts or other high-volume events.

History

On 3 February 2016, SKY Perfect JSAT awarded Lockheed Martin Space Systems a contract to build JCSAT-17 using a modernized variant of the A2100 satellite bus. [5] Eventually, this bus became known as LM-2100, which is expected to provide JCSAT-17 with a minimum 15-year lifespan.

On 4 January 2017, SKY Perfect JSAT announced it had contracted Arianespace to launch JCSAT-17 on an Ariane 5 ECA. [6] The satellite was shipped to Kourou in January 2020. [7]

Spacecraft

JCSAT-17 was built by Lockheed Martin Space Systems on the LM-2100 platform. The spacecraft uses an 18-metre reflecting antenna to provide targeted S-band communications to Japan and surrounding regions. [8] Once in orbit, the new satellite unfurled a 18-metre-diameter S-band mesh communications antenna made by L3Harris Technologies, formerly known as Harris Corp., of Melbourne, Florida. [9] The spacecraft uses Ku-band transceivers for aircraft avionics communications. [10]

Launch

JCSAT-17 was launched from Guiana Space Centre ELA-3 on 18 February 2020 at 22:19:00 UTC aboard an Ariane 5 ECA launch vehicle. As with most Ariane 5 missions, the satellite was co-manifested and therefore shared a launch with the South Korean weather satellite GEO-KOMPSAT 2B.

Approximately 31 minutes after launch, JCSAT-17 separated from the SYLDA fairing and was released into geostationary transfer orbit. [11]

The S-band and C-band payloads on JCSAT-17 will be used by NTT Docomo, a Japanese mobile phone company, to provide mobile connectivity across Japan and surrounding regions, according to Sky Perfect JSAT. [9]

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 A2100 is a model of communications satellite spacecraft made by Lockheed Martin Space Systems. It is used as the foundation for telecommunications payloads in geosynchronous orbit, as well as GOES-R weather satellites and GPS Block IIIA satellites. Over 40 satellites use the A2100 bus.

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.

JCSAT-RA, previously known as JCSAT-12, is a Japanese geostationary communications satellite, which is operated by SKY Perfect JSAT Group.

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.
