ATNF Operations
ATUC 1 May 2007


Decadal Plan
"Continued operational support for existing ATNF telescopes (Parkes, Mopra and Compact Array) is seen as important throughout the next decade. Nevertheless, over this period, resources from these telescopes will increasingly have to be reprioritised into the development and operation of infrastructure on the roadmap to the SKA if Australia is to maintain its world-leading position in radio astronomy. This will ultimately restrict the range of operational modes offered by the Compact Array and Parkes to a smaller number of areas where they can still offer world-class performance by the end of the decade (2015)."

MIRANdA operation
· Sited at Mileura (Boolardy), WA · Data processing centre remote from telescope (Geraldton or Perth) · No user/operator · Operations could be conducted from somewhere else. · "FRUs"­ field replaceable units; remotely diagnosable · Small (1-3) staff on Boolardy site · Maintenance/repair team visit from Geraldton (400km) or Perth (800km).


Questions
· What design features are required in MIRANdA to allow this operational model? · Could any of the features of MIRANdA be used at Parkes (Mopra, Narrabri) to allow smaller on-site presence? · Would fewer, larger groups be beneficial: eg all online software developers/maintainers at one site? · Of our current functions, which do not require full time presence at the observatory?

Conclusions
· The operation of all four ATNF observatories should be considered together; operating costs must be minimised for all, including MIRANdA. · At this early stage in the design of MIRANdA, we are well placed to include features that minimise operating cost. Those operating our current facilities have a broad and useful experience that should benefit MIRANdA design. · There may be opportunities for economy in the operation of Parkes, Mopra and the ATCA if aspects of the operations teams at Parkes and Narrabri are consolidated. This, with a linking of all telescope schedules, could help cope with the peak demands on these teams, and yield some economies of scale in some of the sub-groups. · There must be a cost to changing our operations. The hope is that this can be restricted to a loss in scheduling flexibility and a less efficient use of telescope time for astronomy (including an increase in "down-time"), and perhaps a financial cost for improving or adding infrastructure to support the new model. · There may also be implications for astronomer access to the telescopes. The level of remote observing possible, the location of observing "control rooms" and operations support staff will all be questioned in the process of setting the new model.
