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.[4]
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]
