JCSAT-17 is a geostationary communications satellite operated by SKY Perfect JSAT Group. The satellite was designed and manufactured by Lockheed Martin on the LM2100 platform, and was launched on February 18, 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]
History
On 3 February 2016, SKY Perfect JSAT Group 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 LM2100, 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 LM2100 platform. The spacecraft uses an 18-meter reflecting antenna to provide targeted S-band and C-band communications to Japan and surrounding regions.[8] Additionally, the spacecraft uses Ku-band transceivers for aircraft avionics communications.[9]
Launch
JCSAT-17 was launched from Kourou ELA-3 on 18 February 2020 at 22:19:00 UTC aboard an Ariane 5. As with most Ariane 5 missions, the satellite was co-manifested and therefore shared a launch with 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.[10]
