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

Array Scale Site Purpose & Comments
AAVS02011/2
AA-low 16 elements LocalProve electromagnetic performance in small array. Multiple arrays
AAVS12013/4
AA-low256elements
Selected SKA site strongly preferred.
Single station showing beam performance and the limits of analogue power requirements
AAVS22015/6
AA-low

AAVS Funding
• Self funded by the AA consortium
• Material AAVS1: 1M€
• Material AAVS2: 5M€
– PEP numbers..
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 SKA1
– Tight schedule
• Connect to deliverables of STaN, Computing and Software?• Interference with pre-cursors?
• Need to tackle outstanding issues with existing team up to 1st July 2012– AAVS0 design, build and evaluation, AA-station specification/design
