1. CETC54 contributions Neil Roddis Apr 15, 2010

2. SPDO In Shijiazhuang Covering the area of 2 sq.km. Founded in 1952 Over 5000 employees (543 senior engineers, 1000 engineers) CETC54- ProCCfCETile CETC54 !!!!!!!!!!!!!!

3. SPDO CETC54- Layout Manufacturing Workshop 15 mins 20 mins 30 mins 2 hours

4. SPDO CETC54- Laboratory Joint Laboratory for Radio Astronomy Technology NAOC and CETC54 JLRAT

5. SPDO What do CETC54 want to do? 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 5

6. 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? What would CETC54 be prepared to do? 6

7. SPDO CETC54: strengths Enormous resources Engineers Skilled manpower Sub-contractors Excellent facilities Manufacturing Test ranges Anechoic chamber etc. Low labor cost Fast response Extensive satcom experience Willing to embrace and develop new designs (ASKAP) 7

8. SPDO CETC54: weaknesses Minimal radio astronomy experience But JLRAT should help High noise designs Used to working to satcom specs Attached to established in-house technologies and design solutions? But may be persuaded to adopt new solutions Do it their way or not at all? Resistant to suggestions about manufacture on site 8

9. SPDO What should we ask CETC54 to do? 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. 9

10. We are The North West China Research Institute of Electronic Equipment Institute of Electronic Equipment

11. SPDO NWIEE/CETC39 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’ 11
