Engaging industry The Australian SKA experience
Dr Carole Jackson, CSIRO Astronomy and Space Science
NAOJ, Mitaka, 5 November 2010
Astronomy and SpaceScience(formerly ATNF)
Parkes, NSW
Narrabri,
NSW
• The largest single astronomical institution in Australia (~300 staff)
• Sydney HQ + Parkes (the ‘Dish’), Narrabri (Compact Array), and Mopra, near Coonabarabran.
• Operates NASA CDSCC (Tidbinbilla)
• CSIRO ATNF is designing and building the Australian SKA Pathfinder ASKAP
ASKAP - CASS
Engaging industry – Australian SKA
SKA will need a high level of industry involvement -> mass production and deployment
SKA benefits to industry
- Engage creative energies of the best professionals- Perfect leading-edge techniques and products in a demanding application- Raise company profile/visibility working with high profile, international mega-science project
- Early involvement in a € 1.5 billion (2007) project spanning a wide range of engineering and computing disciplines
SKA - a Global collaboration
Australian SKA Pathfinder (ASKAP)
Australia’s contribution to the SKA - the largest scientific instrument to be built on earth
• ASKAP - an SKA Pathfinder demonstrates• A novel technology advanced array telescope.
• Australia’s candidate SKA site, the Murchison Radio Observatory (MRO).
• Australia’s capacity to host large international projects
• ASKAP’s as a radio telescope - • World’s fastest survey radio telescope at cm frequencies.
• Survey science projects (key drivers)
• Astronomy surveys defined by international groups of astronomers
High-dynamic range, wide field-of-view telescopeNumber of dishes 36 = 630 baselinesDish diameter 12 mMax baseline 6kmResolution 30 arc secSensitivity 70 m2/KSpeed 1.5x105 m4/K2.deg2
Observing frequency 700 – 1800 MHzField of View 30 deg2
Processed Bandwidth 300 MHzChannels 16kFocal Plane Phased Array 188 elements (94x dual pol)
ASKAP - Specification
Australian SKA Industry Opportunity
ASKAP as an SKA Pathfinder • To demonstrate SKA subsystems & key technologies
Engage in early-phase R&D (via co-investment or supply) • Demonstrate capability to international SKA community
• Develop skills
• Foster international relationships (industry & astronomy)
Australian SKA Industry cluster Self-funding group of support companies & Government agencies
Forum for ASKAP/SKA development
Industry briefings, Industry (technical) news & updates from CASS
Networking; showing development of skills towards SKA (to Government)

Published: web based – freely available
Describes how we ensure Australian industry has fair opportunity
(Fairness & Professional Procurement)
ASKAP/SKA technical workshopsVisits/advice from many ASKAIC companies
R&D collaborationsDevelop strong partner suppliers
Industry chiefs meet with Minister Carr.Industry visit to sites
News & ongoing communications
Site management & infrastructure – roads, power, optical fibre
Australian expertise for remote sites
Project management – Build, maintenance, operations & scheduling
Consulted with many companies - Boeing, Raytheon, BAE, etc on
System Engineering best practice
Low-cost antennas
Sought near “off-the-shelf solution” high production rate antennas
Low noise uncooled receiver components (‘receiver-on-chip’)
Working with industry to develop low-cost solutions
High speed, low cost DSP
Seeking low cost solutions off’-the-shelf
High performance computing
ASKAP as a development platform for a “single digital backend “
Australian SKA Industry Opportunities
Engaging industry – Australian SKA
Engaging industry – Australian SKA
ASKAP Antennas - industry supply
Low-cost antennas
Sought near “off-the-shelf solution” antennas
Close to SATCOM x-band 12m commercial antennas
Used open Tender process - very successful, great response from international companies
Negotiated contract with CETC54 for 36 antennas,
- Developed very productive, successful relationship
- New market for CETC54 – international, high profile, civilian
ASKAP antenna = 85% CETC54 ‘production’ design
15% ‘new’ = 3-axis, astronomy precision & RFI specification
ASKAP Antennas - industry supply
ASKAP Antenna team involved in design consultation & ensuring technical specification is delivered
• Contract award October 2008• PPR Mar 2009 • 1st antenna on site January 2010• 6 antennas built October 2010
36 antenna order
“Traditional” panel reflector, heavy antenna
ASKAP rms = 0.5mm (20 GHz)
High precision, low cost.
ASKAP Antennas - industry supply
Successful industry procurement: lessons
1.Long project design leadtime before Tender (4 years)
very well defined technical specification – not a build blueprint
2.Experienced team managing tender, negotiation and
delivery
2.Excellent relationship with CETC54
3.Treated antenna 1 as a
‘design proof of concept’
antenna 2 onwards are ‘production’

ASKAP/SKA Receivers – future?
Allows entire receiver to be housed behind feed• Lightweight and compact• Low power• Low cost (minimal connectors and cabling)• RF in, digital fibre out.
ASKAP/SKA Receivers – industry R&D
Collaborative R&D – strong investment – clear product
- Industry gains IP, designs, etc
- Excellent relationship based on previous R&D

ASKAP/SKA Receivers – industry R&D
Sapphicon 0.25um Silicon on Sapphire process
Direct-down conversion I/Q architecture with divide-by-2 LO• Single out of band LO required• I/Q amplitude and phase match expected to be adequate to ensure
40 dB image suppression
Implementation of whole receiver from LNA to ADC input• Including LO synthesiser and all filters• Minimal external components and cost• LNA off-chip for minimum Tn and maximum flexibility• Off-chip ADC to reduce development cost• Includes high power ADC drivers
Adjustable operations – bandwidth, gain, filters

ASKAP/SKA Receivers – industry R&D
ASKAP R&D Collaboration
Successful collaboration: experience
1.Start –up R&D to establish relationship (LNA)
Agree detailed technical specification – not a build blueprint
2.Get the right expert engineers working together; enthusiasm
Avoid endless discussions on what ‘we might do’
3. Excellent relationship
4.Be very honest where this R&D fits for ‘SKA’
Expectations can be too high.
