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
