STAR Bus is a satellite platform manufactured by Orbital Sciences Corporation with an Apogee kick motor to place a Communications satellite into Geostationary The D3 satellite is to be co-located with C1 to expand capacity.

Optus D1

D1 was successfully launched by an Ariane 5 ECA on 13 October 2006 at 20:56 GMT. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. Events 54 - Nero ascends to the Roman throne 409 - Vandals and Alans crossed the Pyrenees Ariane 5 is a European Expendable launch Ariane 5 is a European Expendable launch Events 54 - Nero ascends to the Roman throne 409 - Vandals and Alans crossed the Pyrenees Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. Greenwich Mean Time ( GMT) is a term originally referring to mean solar time at the Royal Observatory in Greenwich, London [15]

Customers on D1 include the Australian Broadcasting Corporation (ABC), Special Broadcasting Service (SBS), the Seven Network, the Nine Network, Sky Television New Zealand and New Zealand's Kordia (formerly known as BCL). The Australian Broadcasting Corporation, commonly abbreviated to the 'ABC' is Australia's national public broadcaster. The Special Broadcasting Service (SBS is one of two government-funded Australian Public broadcasting radio and television networks, the other being the The Seven Network is an Australian television network, owned by the Seven Media Group.

Freeview is a Non-profit organization providing Free-to-air Digital television and Digital radio to New Zealand. The Kordia transponder will be on 12. 4697GHz. [1]

Incorrect configuration of New Zealand spot beam

During in-orbit testing of the satellite, it was discovered that the New Zealand spot beam had been configured with horizontal polarisation instead of the expected vertical polarisation - as had been used on its predecessor Optus B1. This is a list of the satellites operated by Optus, an Australian telecommunications company [17][18]

As many existing receivers did not have the ability to receive horizontally aligned signals, Sky Television was unable to transfer services from Optus B1 to this beam as expected. SKY Network Television Limited () often trading as SKY is a New Zealand pay Television service Sky was instead assigned capacity on the more general Australia/NZ beam. Due to restrictions on broadcast rights (in terms of both broadcast licensing and copyright), the unencrypted Freeview service could not make a similar allocation switch and was set up as a horizontally-aligned service on the New Zealand spot beam. A broadcast license is a specific type of spectrum licence that grants the Licensee the privilege to use a portion of the Radio frequency spectrum Copyright is a legal concept enacted by Governments, giving the creator of an original work of authorship Exclusive rights to control its distribution usually for Freeview is a Non-profit organization providing Free-to-air Digital television and Digital radio to New Zealand. [2]

On 2007-07-31, Sky successfully performed an over the air software upgrade to all of its customer set-top boxes, enabling them to receive the horizontally-aligned signals from the New Zealand spot beam. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. Events 30 BC - Battle of Alexandria: Mark Antony achieves a minor victory over Octavian 's forces but most of his army subsequently A set-top box (STB or set-top unit (STU is a device that connects to a Television and an external source of signal, turning the signal into Accordingly, Sky was able to return to their original capacity allocation. [19]

D2 was successfully launched from the Guiana Space Centre by an Ariane 5 GS on 2007-10-05 at 22:02 GMT. Ariane 5 is a European Expendable launch The Guiana Space Centre, or more commonly Centre Spatial Guyanais (CSG is a French Spaceport near Kourou in French Guiana. Ariane 5 is a European Expendable launch Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. Events 869 - The Fourth Council of Constantinople is convened to decide about what to do about Patriarch Photius of Constantinople Greenwich Mean Time ( GMT) is a term originally referring to mean solar time at the Royal Observatory in Greenwich, London [21]

Optus D2 replaced Optus B3, which had been in operation for 13 years at the time of D2's launch. [22]

Optus D3 (planned)

The third in the D series of Optus satellites is planned for launch in late 2009 by Arianespace using an Ariane or a Soyuz launch vehicle from Europe's Spaceport in Kourou, French Guiana. Arianespace SA is a French company and was founded in 1980. They undertake the production operation and marketing of the Ariane 5 rocket launcher as part This article is about the rocket developed by the European Space Agency.
