Superbird-B1
Superbird-B1, sometimes identified as Superbird-1B, was a geostationary communications satellite designed and manufactured by Ford Aerospace on the SSL 1300 satellite bus. It was originally ordered by Space Communications Corporation (SCC), which later merged into the SKY Perfect JSAT Group.[4] It had a mixed Ku-band, Ka-band and X-band payload and was rushed into launch at the 162° East longitude due to the launch failure of Superbird-B.[5][6]
It was ordered in 1985 along Superbird-A, Superbird-B and Superbird-A1 on the very first order of the SSL 1300 platform.[5][7][8][9] It was also the second satellite of SCC on orbit and the fourth commercial satellite of Japan to enter operations.[5] It was used for video distribution, news gathering, remote publishing and high definition TV service to the main islands of Japan and Okinawa.[1]
