History

In September 1997, both JCSAT and Space Communications Corporation (SCC) had requested the 110° East position. The Japanese government made both companies share the 110° East position, and thus they both made a joint order on 20 November 1998 for N-SAT 110 from

. JCSAT used the JCSAT-7 designation for this satellite, while SCC used Superbird-5. On 6 October 2000 at 23:00 UTC, an Ariane-42L H10-3 successfully launched N-SAT 110 to a geostationary transfer orbit from

ELA-2. One hour later, at 00:04 UTC, on 7 October 2000, the first signals from the satellite were successfully received from the Australia ground station. On 14 October 2000, at around 03:00 UTC, N-SAT 110 reached the

. Once it was put into orbit, it was renamed as JCSAT-110 by JCSAT and Superbird-D by SCC. On 1 October 2008,

and Space Communications Corporation merged into

, and the satellite was known simply as JCSAT-110.
