JCSAT-2A, known as JCSAT-8 before launch, is a geostationary communications satellite operated by SKY Perfect JSAT Group (JSAT) which was designed and manufactured by Boeing on the BSS-601 platform. It has Ku band and C band payload and was used to replace JCSAT-2 at the 154°East longitude. It covers Japan, East Asia, Australia and Hawaii.[3][2][4]

Satellite description

The spacecraft was designed and manufactured by Boeing on the BSS-601 satellite bus. It had a launch mass of 2,460 kg (5,420 lb) a power production of 3.7 kW and an 11-year design life.[3] Stowed for launch it measured 3.6 m × 2.7 m × 4.3 m (11.8 ft × 8.9 ft × 14.1 ft), with its solar panels and antennas deployed it measured 21 m × 4.3 m × 7.6 m (69 ft × 14 ft × 25 ft).[4][5]

Its payload is composed of sixteen 57 MHz Ku band plus eleven 36 MHz and five 54 MHz C band transponders, for a total bandwidth of 1,578 MHz.[6] Its high power amplifiers had an output power of 120 Watts on Ku band and 34 Watts on C band.[4][5]

The Ku band footprint covers only Japan, while the C band beams cover Japan, East Asia, Australia and Hawaii.[4]


In April 2000, JSAT ordered JCSAT-8 from Boeing (which had acquired the HS-601 business from Hughes), to replace JCSAT-2 at the 154° East slot. It would provide coverage to Japan, East Asia, Australia and Hawaii.[3]

An Ariane 44L successfully launched JCSAT-8 on March 29, 2002 at 01:29  UTC from Guiana Space Centre. Once successfully deployed, it was renamed JCSAT-2A.[3]
