22 May 2008Lynn Baker USSKA Consortia Meeting Washington, DC5 TDP Project PathfindersPrepSKA AWGCPG Technological Interactions

22 May 2008Lynn Baker USSKA Consortia Meeting Washington, DC6 Interaction between AWG and CPG –Science data products result from CPG modeled algorithms –CPG results define the required antenna specifications –AWG provides feasibility and cost models of specifications –Rescoping of science goals leads to multiple antenna options –Early AWG work will focus on low cost design and fabrication

22 May 2008Lynn Baker USSKA Consortia Meeting Washington, DC7 AWG Major Objectives –Fabrication methods and designs to provide low cost antennas –Cost modeling of antennas to estimate optimum parameters –Provide broadband feeds and low noise receivers AWG Work Blocks –Reflector fabrication techniques, especially hydroforming –Antenna mounts, structural support of reflectors –Analysis of environmental effects, solar, gravitation, wind, climate –Reflector optical designs to achieve specifications –Cost modeling of antennas –Broadband feeds, potentially 10:1 bandwidth –Low noise amplifiers matched to feeds

22 May 2008Lynn Baker USSKA Consortia Meeting Washington, DC8 CPG Major Objectives –Feasibility of calibration and processing meeting science goals –Cost modeling WRT array and antenna parameters –Provide antenna specifications to AWG –Demonstrate algorithms on pathfinder data –Liaison with other calibration and processing groups CPG Work Blocks –Signal transport –Calibration algorithms –Imaging, spectroscopy, time domain imaging –Scalability and high performance computing

22 May 2008Lynn Baker USSKA Consortia Meeting Washington, DC9 AWG Meeting, March 2008 First meeting of the AWG and associated experts –Extended presentations from four pathfinder projects –Presentations on composite and hydroformed fabrication –Presentations on low noise receivers and broadband feeds –Presentations on reflector optics designs and tradeoffs –Conclusions from the meeting included in the AWG work plan CPG Organizational Meetings, March & May 2008 –Discussions of goals, work plans and required staffing –Status of recruitment for project
