BSB-R2

NSSDCA/COSPAR ID: 1990-074A

Description

BSB-R 2, a UK TV broadcasting satellite known as Marco Polo 2, was launched using the Delta launch vehicle on August 18, 1990, from Cape Canaveral. It joined a sister craft at 31 deg. w, to provide high-power direct broadcast signals to UK users with antennas as small as 0.3 m. It housed 5 Ku-band transponder channels, but only 3 could be at full power at one time. With both satellite on station, 5 channels could be beamed at full power. The twins were maneuvered to stay in close proximity allowing signals from both to be beamed at the same spot. Built for British Satellite Broadcasting by Hughes Space and Communications Group, Marco Polo 2 was a 2.1-m diameter drum, 2.7 m tall. With solar drum deployed and antenna reflector raised, overall height was 7.2 m. Body mounted solar arrays provided 1,000 W at the beginning of its 10-year life.
