Telescope Verification Requirements
Inputs:• Telescope (Level 1) Requirements
Outputs:• Methods for verification for all telescope-level requirements
(Analysis, Demonstration, Test, Similarity, etc.)• Traceability between Requirements and Verification
Requirements
Telescope Roll-Out Plan
Inputs:• Hosting Agreements• Installation constraints• Verification plan• Science priorities
Outputs:• A clear roll-out plan for all three telescopes,
1. SKA1_LOW2. SKA1_MID3. SKA1_SURVEY
• that forms the basis for delivery of elements and integration activities.

Precursor Integration - ASKAP
What is ASKAP?
ASKAP is a 36 dish telescope- Parabolic dish, 3 axis design- 12m diameter- Baselines ranging from 22m to 6km
ASKAP uses MRO Infrastructure- The control building- Roads- Fibre within the MRO - Trunk fibre to Geraldton- Power reticulation- Weather stations- RFI monitoring
What is ASKAP?
Each dish comprises a Phased Array Feed (PAF) receiver system- Analog receive chain at the dish focus- Digital receive chain in the MRO control building
Combined, each dish + PAF system provides - 36 Dual-polarisation beams supporting 30 deg2 Field Of View- Aperture efficiency of TBC
Beams from each dish combined at the Correlator
Science Processing & Archiving performed at the Pawsey Centre
How to Integrate ASKAP
Strategy for ASKAP Integration
1) Establish signed-off ICDs with other consortia
2) Support SKA1 Elements with interface development
3) Conduct Integration Readiness Review
4) Integrate first ASKAP antenna into SKA1_SURVEY
5) Verify interfaces with SKA1 Elements
6) Integrate remaining antennas
