SATNET.NET.NZ Digital Satellite

At the end of 2003 Orbital was awarded a firm order for two GEO satellites by Sydney, Australia based Optus Networks, Pty. Then, in early 2007, Optus awarded Orbital a contract for a third satellite. Based on Orbital’s STAR platform, the satellites will provide Ku-band fixed communications and direct television broadcasting services to Australia and New Zealand.
The three satellites will initiate Optus’ D-series of satellites. The first two satellites, known as D1 and D2, will generate approximately 3.8 kilowatts of payload power to service 24 active transponders. The third satellite, D3, will generate approximately 5 kilowatts of payload power to service up to 32 active transponders.

IS-8 is located just three degrees west of IS-2, the two satellites offer customers increased flexibility and a range of complementary services throughout the region. Applications include full-time video distribution, telecommunications and Internet-related services as well as live worldwide transmission of special events.
IS-8 highlights:
The platform for delivery of PanGlobal TV which offers a digital video retransmission service using MCPC platforms provided by INTELSAT and GlobeCast Australia, together offering programmers immediate access to an established and growing Australian DTH neighborhood.
Three high-powered Ku-band beams offering dedicated coverage of Northeast Asia, Southeast Asia and Australia with access to the United States.
C-band connectivity between the Asia-Pacific region and the United States, plus access to our Napa and Fillmore, California teleports that serve as hubs for international communications traffic.
One of five satellites serving Asia. In addition to IS-8, these satellites are IS-2, launched in July 1994 and located at 169 degrees east longitude over the Pacific Ocean Region; IS-7, launched in September 1998 and located at 68.5 degrees east longitude over the Indian Ocean Region; IS-10, launched in May 2001 and co-located with IS-7.

NSS-9 177°W
Orbital is building the NSS-9 C-band satellite for SES NEW SKIES, an SES Global company.
The satellite will be positioned at the orbital location of 183 degrees East ( 177°W ),
allowing the NSS-5 satellite to be re-deployed to a new orbital slot.
The contract includes a firm order for one satellite and an option for another satellite,
including turn-key on-orbit delivery. Based on Orbital's STAR 2 satellite bus,
NSS-9 will carry 28 active C-band transponders and feature three beams that can be interconnected
on a transponder-by-transponder basis: a global beam providing coverage of the entire earth visible
from 183 degrees East, a West Hemi beam (covering Australia, Indonesia, the Philippines, Japan,
China, Korea and the Pacific Islands) and an East Hemi beam (providing coverage and connectivity
to the U.S., Hawaii and Polynesia).
The satellite will provide a minimum service life of 15 years.
Customer: SES NEW SKIES - Netherlands
Mission:C-band satellite service featuring global, East or West Hemi beam coverage
Performance:Repeater - 32-for-28 linearized channel amplified dual traveling wave tube amplifiers
(LCDTWTAs) Transponder Power - 2.3 kilowatts Antennas - Two 2.3 m (7.5 ft.) shaped-beam reflectors
