What do CETC54 want to do?
SPDO
•
Win large non-military export contracts
– Last year $100M
– Little profit from ASKAP
•
Manufacture and install all of the SKA dishes
– Manufacture in China, re-assemble on site
•
Use their own fabrication technology
– Session 12 tomorrow
•
Do most, if not all, of the mechanical design
– Also em design
•
Manufacture feeds and receivers

What would CETC54 be prepared to do?
SPDO
•
•
•
Manufacture a mount to TDP design
Manufacture a complete antenna (DVAC) to the TDP
optics design, but using panels.
Virtually anything, if they thought it would lead to
getting the big contract?

CETC54: strengths
• Enormous resources
• Engineers
• Skilled manpower
• Sub-contractors
• Excellent facilities
• Manufacturing
• Test ranges
• Anechoic chamber etc.
• Low labor cost

CETC54: weaknesses
SPDO
•
Minimal radio astronomy experience
•
•
High noise designs
•
•
Used to working to satcom specs
Attached to established in-house technologies and
design solutions?
•
•
But JLRAT should help
But may be persuaded to adopt new solutions
Do it their way or not at all?
•
Resistant to suggestions about manufacture on site
8
What should we ask CETC54 to do?
SPDO
•
Build DVAC in parallel with DVA-1 to the
same specification, but using panels.
– Interesting test of alternative manufacturing
technique
– Integrate and test where?
– Funded by NAOC and CETC54?
•
Manufacture the mount for DVA-1?
– Only if funds are so short that this is the only
way to build DVA-1.

•
Split from CETC54 in 1970s
Similar capabilities and resources
They have made hundreds of 9, 11 and 13
metre antennas.
Also keen to win ‘The SKA Contract’
