BSAT-3b, is a geostationary communications satellite operated by B-SAT which was designed and manufactured by Lockheed Martin on the A2100 platform. It is stationed on the 110° East orbital slot along its companion BSAT-3a and BSAT-3c from where they provide redundant high definition direct television broadcasting across Japan.
BSAT-3b was designed and manufactured by Lockheed Martin on the A2100 satellite bus for B-SAT. It had a launch mass of 2,060 kg (4,540 lb), a dry mass of 975 kg (2,150 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.
It measured 3.8 m × 1.9 m × 1.9 m (12.5 ft × 6.2 ft × 6.2 ft) when stowed for launch. Its dual wing solar panels can generate 3 kW of power at the end of its design life, and span 14.65 m (48.1 ft) when fully deployed.
It has a single Ku band payload with 8 active transponders plus four spares with a TWTA output power of 130 Watts.
April 15, 2008 Lockheed Martin announced that it had also been awarded the second contract of the B-SAT third generation broadcast satellite fleet for BSAT 3b. It had already produced BSAT-3a, which launched on 2007, and would eventually also produce BSAT-3c. BSAT-3b would be based on the A2100 platform, sport 8 Ku band transponders (plus 4 spares) and have a design life of 15 years. It was going to be located at the 110° East orbital position. It was to be launched aboard an Ariane 5 ECA in the second half of 2010.
