Optus successfully launched the D2 satellite on 6th October 2007 from French Guiana in South America. Optus D2 was Optus' 9th satellite construction and launch programme. The successful launch of D2 represents the next step in our strategy to strengthen the Optus satellite fleet, and build on our leadership position in Satellite.
The Optus D2 satellite has replaced the Optus B3 satellite which is nearing the end of its life, having been in operation since 1994. D2 will deliver an improved experience for our customers by increasing our satellite capacity and resilience, further enhancing our communications capabilities unmatched by any other telecommunications company in Australia.
D2 will also deliver significant growth opportunities in the direct-to-home TV market; while increasing our capacity to deliver high speed data services to rural and regional Australia. With D2 scheduled to remain in orbit until 2020 Optus' commitment to meeting our customers' long-term satellite capacity needs is assured.
