Why Satellite?
Enable the Digital Economy
• Building a National Broadband Network
for ALL Australians
• Using a Multi Technology Mix (MTM) of
technologies to deliver broadband
Close the Digital Divide
• Satellite becomes a cost-effective choice
beyond the economical reach of other
technologies
• Uniform National Pricing to deliver LTS
services at subsidised prices.

“* We’re designing the NBN to provide these speeds to our wholesale customers, telephone and internet service providers. End user experience, including the speeds actually achieved over the NBN, depends on the technology over which services are
delivered to your premises and some factors outside our control like equipment quality, software, broadband plans and how the end user’s service provider designs its network.”

ISS Capacity Upgrades
Upgraded Capacity
• Satellite capacity upgraded
• Re-balanced network with ~1,200 end-user services re-pointed
Agreed New Fair Usage With RSPs
• New WBA & Fair Use rules to access to capacity
• New control mechanisms for breaches
Developed Tools to Monitor & Enforce Fair Usage
• New tools for RSP compliance with Fair Use,
along with end-user experience
• Work with RSPs to help them manage plans, customers and
network configuration – eg. 2% of users consume 20% of capacity
Launched NSS
• Launched to plan 1 August 2014
• Early pulse of customer experience highlighted some teething
issues but overall good satisfaction with the service

LTS: On track for success!
• NBN Co is on track to launch the product
late 2015 or early 2016
• Strategic Review recommendations on some
further risk mitigation also included in plans for
implementation
• The LTS network build continues to
track to budget
• There is no room for complacency:
Building and launching satellites, and the
space industry in general is a
RISKY BUSINESS!

LTS: Covering Australia….
Unprecedented High-Throughput
Satellite performance in the region
• Ka-Band
• 101 tailored spot beams
• Large geographical coverage
• Aggressive reuse of limited
RF spectrum
• Highly available solution design
• Two satellite system ~

Space Segment: Progressing Well
• Manufacture of the NBN 1A and 1B spacecraft is
progressing well.
• SS Loral manufacturing both satellites in US.
• Both satellites will be launched by Arianespace
in French Guiana.
• The thermal vacuum testing for NBN 1A has
recently been completed with favourable test
results.
• This is a major milestone for the space segment
of the program with the vibration dynamics,
acoustics and deployment tests remaining.

Ground Systems: Moving Ahead…..
• The first production versions of the modem are in being tested now in the
US with excellent results (BER, link performance etc).
• The first product launch ready version of the system software is currently
being testing in the Ground System Test Bed at the National Test Facility
• This represents the first ‘production ready’ version of the system software.
• Testing is underway at 9 of the 10 gateways.
