OPTUS D2
INFORMATION
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 optus customers by increasing the
satellite capacity and resilience, further
enhancing Optus 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 the
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 its customers' long-term satellite
capacity needs is
assured.
