Operational Principles
3. The purpose of the SKA Observatory will be to enable scientists to pursue world-leading scientific programmes, to organise and conduct improvements and upgrades of the SKA telescopes in order to provide and maintain facilities that are at the forefront of science and technology, and to ensure the protection of the SKA sites for the SKA and future radio telescopes.
Previous Work
Operational Principles
6. The expected lifetime of the SKA Observatory is 50 years.
Previous Work
Access Principles• based on scientific merit• single time-allocation process• proportional to contribution• limited access for non-member states• data products to be made globally available after a
suitable proprietary period
…policy to be defined in detail
Previous Work
• Late start to operations planning• Structure of the organisation • Hosting arrangements in AUS/RSA• Role of Regional Centres • Challenge of “Big Data” • Reliability & maintenance • Power• Operations budget • Precursors: integration of MeerKAT and operational
experience
The Big Issues
Operational Model• support both large, multi-year programmes (KSPs)
and conventional PI projects• 24-hour operation; service observing; automated,
flexible observing queue• “observing factory”• ToOs and transients; subarrays and commensality• high level of user support• on-the-fly maintenance and repair• RFI constraints; minimal staff on site
Current Work
Logistics Engineering• availability requirement: >95% capacity for >90% of
the time• modelling of failure modes and reliability• to inform maintenance plan and staffing
requirements• RAM report and FMECA reports are CDR
deliverables• two new draft documents to be issued imminently:
– Support Concept– RAM Allocations
Current Work
RAM/ILS Modelling and Maintenance Planning
Wed 13:30
Operations Concept Document• to describe operational model• to specify additional Level-1 requirements from the
operations perspective• draft to be issued soon for comment – input from
design consortia welcome• Operations Concept Review planned Q1 2016• approval of new requirements through ECP process
Current Work
Operations Plan– Contents:
• Operational model• Structure of the organisation • Staffing• Budget
– For presentation to the Board along with Construction Proposal (Jan 2018)
Current Work
• Unique challenge• globally-distributed project• return on investment• no perfect solution
• Status• discussed at Board in July• going to Board next week for approval
• Context• steady-state operations• SKA1 designed, built, commissioned and fully operational (2023 on
current planning)• assume IGO is in place
Structure of the Organisation
• Some relevant principles:• The SKA is one observatory and must present a
single, seamless interface to the user community.– the “one observatory” model
• The structure should be designed to optimise the operation.
• Duplication of staff should be minimised. Common functions should be based at the GHQ.
• CSIRO and SKA-SA will have built up experience of operating telescopes on the two sites; SKA must retain access to this experience.

• Strategy• bottom-up approach• opex estimate was a PDR deliverable from consortia• designs should minimise whole-life costs• additional costs to be estimated• PDR-level estimate to be presented to Board in April 2016• updates to every subsequent Board meeting• final, CDR-level estimate will be presented to Board for
approval along with Construction Proposal (January 2018)
• Budget team• me, Douglas Bock (AUS), Adrian Tiplady (RSA)
Operations Budget
Operational Principles
20. The SKA Observatory will calibrate SKA data and make science-ready data and ancillary products available to the users.
21. The SKA Observatory will provide an archive with a data management system to support data-intensive astronomy.
22. The SKA Observatory will provide user support and tools to enable exploitation of SKA data.
Current Work
Data Flow• construction project capped at €650M• scope of work includes generation and storage of
data products in AUS/RSA• it does not include delivery of data to users or
further processing• essential for full science exploitation of the SKA• Data Flow Advisory Panel set up by Board in July• will report back to Board in April 2016• ToR distributed to consortia
