Station 1 2 N

Baseline

Baseline longer Resolution increased(VLBI: ~milliarcsec.)

# stations higher Improved calibration & imaging

Larger collecting area Increased sensitivity(In R.A. expressed as Aeff/Tsys )

Other aspects: •Frequency bandwidth (span, instant.)•Dynamic range (in image map)•RFI•Configuration, Site•Steaming Data, Computing power, Archiving•Network performance etc.

Many inderdependencies!

Configuration Resolution, imaging, brightness sensitivity etc.

Design Studies 1 to8

• Work has Clear objectives, Milestones and Deliverables to provide outcomes in measurable and verifiable form.

• DS1: Overall coordination and management. • DS2-6: Activity Cores, sub-divided into 21 coherent Design Study Tasks (DSx-Ty) • DS 7-8: “Synthesizing” the results from DS2-6

Structure optimized to continuously map the scientific requirements on the technical specifications to produce a common design goal SKADSUKJBOAvA171204
