Astra 1B

Astra 1B was the second of the Astra communications satellites launched and operated by SES (Soci t Europ enne des Satellites). It was bought during its construction from GE Americom, and was launched to add extra capacity to the satellite television services from 19.2 east, serving Germany, the UK and Republic of Ireland.

It was believed to have been launched in a faulty condition, and suffered a thruster failure early in its life, causing minor drift, meaning that it became permanently difficult to obtain a steady lock on the satellite. This was most notable on analogue transmissions where the picture would move from clear to carrying sparklies and back again.

Along with Astra 1C, Astra 1B was to be replaced in 2002 with Astra 1K, which failed to launch successfully, and as a result it continued to serve a longer life than expected, only falling from use when digital television on Astra 2A removed the majority of UK and Ireland targeted channels from 19.2 east.

From 2005, SES claimed that the satellite was in use for VSAT services, however no transponders were powered, and the satellite drifted to around 19.5 east. One transponder was reactivated in October 2005, but was carrying only colour bars.

On June 16, 2006 SES confirmed that Astra 1B would be decommissioned and de-orbited within weeks after Astra 1KR, the satellite which would replace Astra 1B and 1C, reached the operational orbital position of 19.2 east.[1] It was officially end-of-lifed on July 14, 2006; close to four years after it had ceased carrying signals, ending SES's claims that the craft was operational.
