Optus D1 is an Australian communications satellite .
The client for the construction of the satellite was Optus Networks . The satellite serves as a communications satellite for Australia and New Zealand via the Ku band and transmits television signals. Optus D1 replaced the previous Optus B1 satellite, whose planned lifespan was expiring.
The satellite was built by Orbital and is the most powerful that the company has ever built. He carries 24 Ku-band transponders. It is able to provide 4.7 kilowatts of electrical power. The satellite has a mass of 2380 kilograms and its planned lifespan is 15 years.
The launch of the satellite took place on October 13, 2006 with an Ariane 5 launcher . He is currently stationed at 160.0 ° East . Due to an incorrect configuration (incorrect polarization) of a transponder for supplying New Zealand by the manufacturer, transmissions from the satellite cannot be received there by most users.
In addition to the Optus D1 satellite, the Optus D series also includes the Optus D2 and Optus D3 , which were launched on October 5, 2007 and August 21, 2009.
