BSat 2A

 2001-011B


BSat 2a and 2b will be Orbital Star (NovaStar) 550 kg (dry) lightsats. They will provide HDTV digital broadcasting from the 110E slot.

BSat-2a is underneath Sylda. Mass is 1317 kg launch, 535 kg dry. Size is 3.8 x 2.5 x 2.0m with 16.1m span.

The EPC orbit of 243 x 1884 km given in the EADS press kit is probably a typo for 43 x 1884 km.

According to C. Niederstrasser of Orbital the satellite was decommissioned in Jan 2013, 1.5 years after being sent to the GEO graveyard; presumably there was interest in studying the long term surivival of the first of this class of spacecraft.
