Satellite description
BSAT-3a was designed and manufactured by
It measured 3.8 by 1.9 by 1.9 metres (12.5 ft × 6.2 ft × 6.2 ft) when stowed for launch. Its dual wing solar panels can generate 2.8 kW of power at the end of its design life, and span 14.65 metres (48.1 ft) when fully deployed.[3]
It has a single Ku-band payload with 8 active transponders plus four spares with a TWTA output power of 130 watts.[2]
Launch
On 19 June 2007, Lockheed announced that it was poised to deliver BSAT-3a on the third quarter of 2007, with another Japanese spacecraft, JCSAT-11. BSAT-3a was the sixth broadcasting satellite procured by B-SAT.[9]
On 10 August 2007, Lockheed announced that BSAT-3a was mated to the launcher and ready for its ride to orbit.
It was entered into service on 1 October 2007 after successfully passing the on-orbit deployment and checkout phase.[2][13]
