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.{{Cite web|date=2020-02-18|title=Japanese communications satellite and South Korean weather satellite launch on Ariane 5|url=https://spacenews.com/japanese-communications-satellite-and-south-korean-weather-satellite-launch-on-ariane-5/|access-date=2020-06-04 |website=SpaceNews.com}} 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.{{cite web|date=2016-02-03|title=Sky Perfect JSAT Awards Lockheed Martin Contract for JCSAT-17 Satellite|url=https://www.satellitetoday.com/innovation/2016/02/03/sky-perfect-jsat-awards-lockheed-martin-contract-for-jcsat-17-satellite/|access-date=2020-06-05|website=Via Satellite}} 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.{{Cite web|title=Arianespace to launch JCSAT-17 for SKY Perfect JSAT |url=https://www.arianespace.com/press-release/arianespace-to-launch-jcsat-17-for-sky-perfect-jsat/|access-date=2020-06-05|website=Arianespace}} The satellite was shipped to Kourou in January 2020.{{cite web|date=2020-01-15|title=Lockheed Martin Ships JCSAT-17 Satellite to Launch Site|url=https://www.satellitetoday.com/launch/2020/01/15/lockheed-martin-ships-jcsat-17-satellite-to-launch-site/ |access-date=2020-06-05|website=Via Satellite}}
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.https://www.arianespace.com/wp-content/uploads/2020/02/VA252-launchkit-EN2.pdf - 18 February 2020 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. The spacecraft uses Ku-band transceivers for aircraft avionics communications.{{cite web|title=StackPath|url=https://www.intelligent-aerospace.com/commercial/article/16544776/kuband-highpower-satcom-transceiver-for-commercial-aircraft-avionics-introduced-by-smiths|access-date=2020-06-04|website=intelligent-aerospace.com}}
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.{{Cite web|title=Space Launch Report |url=https://www.spacelaunchreport.com/|access-date=2020-06-05|website=spacelaunchreport.com}}
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.{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2020-013A|title=Display: JCSAT-17 2020-013A|publisher=NASA|date=14 May 2020|access-date=24 July 2020}} {{PD-notice}}
