2. PEP Project Execution Plan for the pre construction phase of the SKA Consortium to be formed AA-low ready for construction AA-mid part of the Advanced Instrumentation Program (AIP) 2012-2016

3. Allocation of Requirements from System to Element level Pre-Stage 1 System RR Element SRR 1 st allocation is science requirements, operations requirements (Instrument Requirements Review). Later allocations are extensibility requirements and non-functional requirements. System Level (SPDO/SPO) Element Level (WPCs) 1 2

13. AA-low Demonstrators Array ScaleSitePurpose & Comments AAVS0 2011/2 AA-low16 elements Local Prove electromagnetic performance in small array. Multiple arrays AAVS1 2013/4 AA-low 256 elements Selected SKA site strongly preferred. Single station showing beam performance and the limits of analogue power requirements AAVS2 2015/6 AA-low,000’s of elements in single or multiple arrays Selected SKA site. Multiple stations, similar to AAVS1, to show imaging performance. Final proving for SKA 2. Small numbers of beams for processing reasons. NOT a science instrument AAVS2 science capable

17. Notes A site decision delay impacts AAVS1/2 SKA site needs to be ‘happy’ to host AA Verification Systems Significant step needed from pathfinders to SKA 1 –Tight schedule Connect to deliverables of STaN, Computing and Software? Interference with pre-cursors? Need to tackle outstanding issues with existing team up to 1 st July 2012 –AAVS0 design, build and evaluation, AA-station specification/design
