Source-derived summary

JCSAT-15 is a communications satellite designed and manufactured for SKY Perfect JSAT Group by SSL on the SSL 1300 platform. It has a launch weight of 3,400 kg (7,500 lb), a power production capacity of 10 kW and a 15-year design life. Its payload is composed of Ku band and Ka band transponders.

SKY Perfect JSAT Group will use JCSAT-15 as a replacement of N-SAT-110.

History

In April 2014, SSL announced that it had been awarded a contract by SKY Perfect JSAT Group to manufacture two satellites: JCSAT-15 and JCSAT-16. The former would be a 10 kW satellite to be a replacement of N-SAT-110 plus expansion capability.

On Sep 8, 2014 Arianespace announced that it had signed a launch service contract with JSAT for the launch of JCSAT-15 aboard an Ariane 5 ECA rocket, and the launch occurred on December 21, 2016.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “JCSAT-15”, the useful work is to connect “japanese satellite” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 14, 2026. The linked authority identifier is Q18466412. The first chronological checks are 1300, 2014 and 2016.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
