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
