4. 17 November 2008Lynn Baker US SKA Consortia Meeting Madison WI4 Work Package 2 Kickoff Meeting Manchester, England November 10-14, 2008 TDP work block structures well aligned with SPDO work blocks Concerns and differences on schedules and timelines Parallel execution of work blocks presents decision making challenges SPDO documents need to better reflect total TDP contributions

5. 17 November 2008Lynn Baker US SKA Consortia Meeting Madison WI5 TDP / DRAO Collaboration DRAO developing high performance, cost effective composite reflectors DRAO developing focal plane phased array feeds TDP studying overall antenna designs but not working on PAF’s Integrate DRAO results into TDP evaluation of antenna technology Provide DRAO with subsystem information and design to support their efforts

6. Mk2 Reflector with Phased Array Demonstrator feed attached. Mk2 reflector has improved: Surface accuracy Stiffness Manufacturability Cost

7. 17 November 2008Lynn Baker US SKA Consortia Meeting Madison WI7 Patriot Antenna Systems Study Contract Short (~6 month) study to provide costing of 2 exemplar antennas Estimate costs as specifications of exemplars are changed Study extension of antenna fabrication technology to lower costs Study improved mounts for cost savings

8. 17 November 2008Lynn Baker US SKA Consortia Meeting Madison WI8 TDP Planned Measurement Facilities Feed and LNA development requires accurate and consistent measurements Noise measurement of feed/LNA combinations, based on cold sky technique, needs radio quiet location, possibly NRAO, Greenbank Feed measurements require a good antenna range. Cost estimates of a range at Cornell will be compared with commercial options.
