Optus D3
Australian geostationary communications satellite
Optus D3 is an Australian geostationary communications satellite , which is operated by Optus and provides communications services to Australasia . D3 was the third Optus-D satellite to be launched. It is a 2,401-kilogram (5,293 lb) satellite, which was constructed by Orbital Sciences Corporation based on the Star-2.4 satellite bus , with the same configuration as the earlier Optus D2 satellite.[ 2]
It was launched, along with the Japanese JCSAT-12 satellite, by Arianespace . An Ariane 5ECA rocket was used for the launch, which occurred from ELA-3 at the Guiana Space Centre in Kourou , French Guiana . The launch took place at 22:09 GMT on 21 August 2009, at the start of a 60-minute launch window .[ 3]
Optus D3 separated from its carrier rocket into a geosynchronous transfer orbit , from which it raised itself to geostationary orbit using an IHI -500-N apogee motor . It has a design life of fifteen years, and carries thirty two J band transponders (US IEEE Ku band).[ 2]
