Communications

Mission Description

Built for Australia-based Optus Networks Pty Limited, the Optus D-Series satellites provide Ku-band

xed communications and direct television broadcasting services to Australia and New Zealand. The

Orbital-built satellites satisfy Optus' need to replace aging on-orbit spacecraft as well as satisfy higher

than anticipated demand for access to their C1 satellite. D1 was launched in October 2006 and

replaced the Optus B1 satellite at 160 degrees East Longitude; D2 was launched in October 2007 and

replaced the Optus B3 satellite at 152 degrees East Longitude.

Spacecraft

The D-Series satellites are based on Orbital’s ight-proven GEOStar-2

™

bus. Each satellite carries

24 active Ku-band transponders on a platform that is ideal for telephony, data and broadcasting

applications. Both spacecraft generate approximately 3.8 kilowatts of payload power.
