JCSAT-17 is ageostationarycommunications satellite operated bySKY Perfect JSAT Group. The satellite was designed and manufactured byLockheed Martin Space on theLM-2100 platform, and was launched on 18 February 2020 on anAriane 5.[3] The satellite mainly provides service to Japan and the surrounding regions. Utilizing severalS-bandtransponders with a flexible processor, the satellite has the capability to redirect communications capacity to concentrate on disaster relief efforts or other high-volume events.[4]
On 3 February 2016,SKY Perfect JSAT awardedLockheed Martin Space Systems a contract to build JCSAT-17 using a modernized variant of theA2100 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 contractedArianespace to launch JCSAT-17 on anAriane 5 ECA.[6] The satellite was shipped toKourou in January 2020.[7]
JCSAT-17 was built byLockheed Martin Space Systems on theLM-2100 platform. The spacecraft uses an 18-metre reflectingantenna to provide targetedS-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 byL3Harris Technologies, formerly known asHarris Corp., ofMelbourne,Florida.[9] The spacecraft usesKu-band transceivers foraircraftavionics communications.[10]
JCSAT-17 was launched fromGuiana Space CentreELA-3 on 18 February 2020 at 22:19:00 UTC aboard anAriane 5 ECAlaunch vehicle. As with most Ariane 5 missions, the satellite was co-manifested and therefore shared a launch with the South Koreanweather satellite GEO-KOMPSAT 2B.
Approximately 31 minutes after launch, JCSAT-17 separated from theSYLDA fairing and was released intogeostationary transfer orbit.[11]
The S-band and C-band payloads on JCSAT-17 will be used byNTT Docomo, a Japanese mobile phone company, to provide mobile connectivity across Japan and surrounding regions, according to Sky Perfect JSAT.[9]
