Satellite description
BSAT-2b was designed and manufactured by Orbital Sciences Corporation on the STAR-1 satellite bus for B-SAT. It had a launch mass of 1,317 kg (2,903 lb), a dry mass of 927 kg (2,044 lb), and a 10-year design life.[9] As all four STAR-1 satellites, it had a solid rocket Star 30CBP apogee kick motor for orbit raising, plus 200 kg (440 lb) of propellant for its liquid propellant station keeping thrusters.[4][2][10]
It measured 3.76 m × 2.49 m × 2.03 m (12.3 ft × 8.2 ft × 6.7 ft) when stowed for launch. Its dual wing solar panels can generate 2.6 kW of power at the beginning of its design life, and span 16.10 m (52.8 ft) when fully deployed.[9]
It has a single Ku band payload with four active transponders plus four spares with a TWTA output power of 130 Watts.[3][9]
History
In March 1999, B-SAT ordered from Orbital Sciences Corporation two satellites based on the STAR-1 platform: BSAT-2a and BSAT-2b.[7] This was the second order of the bus and the first since Orbital had acquired CTA Space Systems, the original developer.[2]
BSAT-2b was launched aboard an
On January 28, 2014, BSAT-2b decayed from its orbit and burned in the atmosphere.[1][8]
