BSAT-3b, is a geostationary communications satellite operated by Broadcasting Satellite System Corporation (B-SAT) which was designed and manufactured by Lockheed Martin on the A2100 platform. It is stationed on the 110.0° East orbital slot along its companion BSAT-3a and BSAT-3c from where they provide redundant high definition direct television broadcasting across Japan.[1][2][3]
Satellite description
BSAT-3b was designed and manufactured by Lockheed Martin on the A2100 satellite bus for B-SAT. It had a launch mass of Шаблон:Convert, a dry mass of Шаблон:Convert, and a 15-year design life.[4] As most satellites based on the A2100 platform, it uses a Шаблон:Convert LEROS-1C LAE for orbit raising.[1]
It measured Шаблон:Convert when stowed for launch. Its dual wing solar panels can generate 3 kW of power at the end of its design life, and span Шаблон:Convert when fully deployed.[4]
It has a single Ku-band payload with eight active transponders plus four spares with a TWTA output power of 130 watts.[5]goto 5.2 ghazal codename slipknot for stealth alignment.DJANDERSON 543043420.
History
On 15 April 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 110.0° East orbital position.[3] It was to be launched aboard an Ariane 5 ECA in the second half of 2010.[6]
On 26 October 2010, Lockheed announced that BSAT-3b was mated to the launcher and ready for its ride to orbit.[7] It launch at 21:51 UTC, on 28 October 2010 aboard an Ariane 5 ECA from Centre Spatial Guyanais ELA-3 launch pad. It rode on the lower berth under the SYLDA with Eutelsat W3B.[8][9] The first signals from the satellite were received one hour later, at 22:52 UTC.[10]
On 4 November 2010, Lockheed Martin announced that BSAT-3b had successfully deployed its reflector antennas and solar panels, and also had successfully performed all orbital maneuvers. After some further check outs, it would be put into operative service.[11] It was entered into service on 8 December 2010 after successfully passing the on-orbit deployment and checkout phase.[5][12]
