JCSAT-17 is a geostationary communications satellite ordered by SKY Perfect JSAT Group to be designed and manufactured by Lockheed Martin on the A2100 platform with a 15-year design life.[3][1] Its payload is composed of S band transponders with a flexible processor that will allow it to redirect capacity to concentrate on disaster relief efforts or other high-volume events.[4]
History
JCSAT-17 is the 21st SKY Perfect JSAT satellite launched by Arianespace.
The S-band and C-band transponders will serve NTT DOCOMO, Inc., the largest telecommunications company in Japan, for its flexible mobile communications services in Japan and the surrounding region under IRU contract (Indefeasible Right of Use). SKY Perfect JSAT will support NTT DOCOMO’s satellite communication services. SKY Perfect JSAT Corporation is a provider of both pay TV broadcasting and satellite communications services. Arianespace has been present in Japan for more than 30 years, with the opening of an office in Tokyo in 1986.Since 1989, Arianespace has launched an average of one Japanese satellite per year. JCSAT-17 will also be the 32nd satellite launched by Arianespace for Japan. Built by Lockheed Martin Space, JCSAT-17 will be the 47th satellite made by this manufacturer to be launched by Arianespace.[5]
On 3 February 2016, Lockheed Martin announced that it had been awarded a contract by SKY Perfect JSAT Group to manufacture JCSAT-17.[4] On 4 January 2017, Arianespace announced that JCSAT-17 will fly on board an Ariane 5 carrier rocket in 2019.[2]
Spacecraft
Built by Lockheed Martin Space, the new name, upgraded performance – the modernized A2100 is now the LM 2100.[6] The 5,857 kg spacecraft LM 2100 will provide S-band, C-band and Ku-band mobile phone and broadcast services over Japan and surrounding regions. It would a 15-year design life. This geostationary communications satellite will deliver communications to users in Japan and the surrounding region. JCSAT-17 payloads incorporate S-band, C-band and Ku-band transponders, which will provide satellite communication services.[7]
