Failures

Satellite Control Processor

On 21 May 2005 services were temporarily lost when the Primary Satellite Control Processor failed. The satellite was switched to use the Backup SCP in order to restore services. Thereafter the satellite continued to operate from the Backup SCP.

March 2006 Positioning Failure
At 06:52 GMT on 30 March 2006, a routine repositioning manoeuvre failed, resulting in loss of pointing control of the satellite. Although communication with the satellite was not lost, transmission services provided by the satellite failed due to its incorrect positioning. Services were progressively restored between 18:00 and 20:00 GMT.

Local time at the time of the start of the outage ranged from 14:52 AWST

 to 18:52 NZST, a peak time for listeners and viewers of the radio and television broadcast and subscription services provided directly or indirectly by the satellite.

Optus B2

  • Launch Date: 21 December 1992


The launchcraft containing Optus B2 exploded on launch and was subsequently destroyed, for reasons that the designer Hughes and the Chinese (Launch Location) authorities were unable to determine.

However, according to one source, shortcomings in the launch vehicle guidance system meant that it failed to compensate for wind-shear effects within the first minute after launch.
