JCSAT-4B, known as JCSAT-13 before launch, is a geostationary communications satellite operated by SKY Perfect JSAT Group (JSAT) which was designed and manufactured by Lockheed Martin on the A2100 platform.
The spacecraft was designed and manufactured by Lockheed Martin on the A2100 satellite bus. It had a launch mass of 4,528 kg (9,983 lb) and a 15 year design life. As most satellites based on the A2100 platform, it uses a 460 N (100 lbf) LEROS-1C LAE for orbit raising.
Its payload is composed of thirty-two 27MHz and twelve 36MHz Ku band transponders, for a total bandwidth of 1.296 GHz, and its used primarily for multi-channel pay per view business. Besides the main beam, it has two steerable beams that enables it to reconfigure in orbit its services.
It's mainly used for broadcasting digital televisions channels It has two fixed beams named Japan Beam and South East Asia Beam. The former offers coverage from the Middle and Near East through South West Asia, South East Asia and Oceania. With the latter mainly covering Indonesia and Malaysia. In addition to the two fixed beams, it offers two steerable beams to cover zones where demands has surpassed the fixed beam capacity.
On April 16, 2009 JSAT made its seventh order for an A2100-based satellite from Lockheed, the JCSAT-13. It would feature 44 Ku band transponders with two steerable antennas for on-orbit reconfiguration. It was to be launched in 2013 for the 124°East slot where it would replace JCSAT-4A. The next day, April 17, Arianespace announced that they had secured the contract to launch JCSAT-13 on an Ariane 5 ECA.
