Transcription
Satellite
Space Communications Corporation (SCC) of Tokyo, Japan, ordered its second spacecraft from Hughes Space and Communications (HSC), on 6 April 1998.[2] It was built at the Los Angeles plant, California, United States.
Launch
Launch occurred on 18 February 2000, at 01:04 UTC.[4] The launch was contracted by Arianespace, and used an Ariane 44LP H10-3 launch vehicle flying from ELA-2 at the Centre Spatial Guyanais. Following its launch and on-orbit testing, it was placed in geostationary orbit at 162° East, from where it provides communications services to Japan. It is equipped with thirty five transponders. Currently, the J-Alert (Japanese emergency warning system) is broadcast via Superbird-B2.[1]
