JCSAT-3A (formerly JCSat 10 ) is a commercial Japanese communications satellite . On August 11, 2006, it was transported into space by an Ariane 5 launcher .
JCSAT-3A has a mass of approximately 4,050 kilograms. It was launched by an Ariane 5, together with Syracuse 3B , in the GTO and then stationed in the GEO at the position 128 ° East . The task of the satellite is to support the Japanese telecommunications company JSAT Corporation with its services in the Asia-Pacific region and Hawaii, and above all to support the JCSat 3 satellite , which is why the name after the start of JCSat-10 in JCSat- 3A was changed. The satellite has a mixed relay package of 30 Ku-band transponders and 12 C-band - transponders on board.
The satellite was manufactured by Lockheed Martin based on the A2100AX satellite bus.
Other satellites
Another model of the JCSat series - JCSAT-11 - was scheduled to launch on September 5, 2007 with a Proton-M / Bris-M rocket. The practically identical satellite (same technical data except for the mass of 4007 kg) should serve as a reserve satellite for the JCSat series. Due to a failure of the rocket, it exploded in the 139th second of flight at an altitude of 76 kilometers, whereby the satellite was also lost.
Immediately afterwards, the identical JCSAT-12 was ordered from Lockheed Martin as a replacement . It was launched on August 21, 2009 at 22:09 GMT with an Ariane 5ECA in Kourou from the ELA-3 launch site together with the Australian Optus D3 satellite. After the successful launch, it was renamed JCSAT-RA and serves as a reserve for the older JCSAT-R .
In April 2009, the company also received an order to build a modified JCSAT-13 satellite , which is due to be launched in 2013.
