Engineering Operations
CSIRO. ATNF Engineering Operations: Parkes Development Projects
Engineering Operations – What we do
• Day-to-day maintenance of ATNF radioastronomy facilities at Parkes, Narrabri, Coonabarabran and (in the future) the Boolardy WA Murchison Radio Observatory (MRO).
• Preventative and corrective maintenance.• Planning for future operations.• Development Projects, facilitating the remote operation of the
Parkes 64m radiotelescope, including planning, development and commissioning, with the support of the ATNF Technologies Theme staff.

Remote Operations?
‘To enable computer control & monitoring of standard telescope
systems’
• Health & Safety (HSE);
• Reliability;
• Rationalise legacy systems
• Scheduling improvements
• Science Operations Centre
DEVELOPMENT PROJECTS:
• 115 - Parkes Drive Control
• 117 - Parkes Control & Monitor
• 118 - Parkes Receiver Fleet

Health, Safety and the Environment
SAFETY IS PARAMOUNT FOR REMOTE OPERATIONS!
CSIRO. ATNF Engineering Operations: Parkes Development Projects
115 - Parkes Drive Control
Objective: Computer control of the MCP (manual Control Panel):
•Development platform hardware nearing completion
•Documented software
•Procedures for safe remote operation
CSIRO. ATNF Engineering Operations: Parkes Development Projects
117 - Parkes Equipment Control & Monitor
Objective: Safe, reliable remote monitoring & control of critical telescope systems.
• Focus Cabin• In practice a “remote site”.
• Need monitoring and diagnostic access to the major subsystems (DC power, receiver & translator).
• Improved connectivity, including video and audio monitoring.
• Vibration monitoring
CSIRO. ATNF Engineering Operations: Parkes Development Projects
117 - Parkes Equipment Control & Monitor
• Conversion system and signal distribution
• Rationalisation of signal distribution, replacement of manual patch panels with a computer controlled switching.
• RF/IF switching matrix
• Calibration computer controllable (done!)
• Multiband conversion system attenuators computer controllable (done!)

Parkes Equipment Control & Monitor
• Power systems• Diesel/UPS control
• Remote monitoring, diagnostics
• Synchroniser unit for the generator – reliability and remote control & monitoring.

118 - Parkes Receiver Fleet Rationalisation
Objective: Establish a maintainable set of receivers consistent with expected science demand. Planning under way on:
• S/X band – Modify MARS receiver package (widen X-band bandwidth, add S-band LNA’s, design/manufacture new dual-band S/X feedhorn) and add to the Parkes Conversion System ;
• L band (H-OH) – Design & fit new improved feed system;
• C-band – Convert existing K/Ku package with new LNA’s to cover at least 4.8-6.8 GHz (target 4 – 12 GHz);
NOTE: Concurrent demands/competing priorities from other projects for the same ATNF Technologies staff resources → including ASKAP and Project 117 (RF/IF monitoring).

Development Projects – Systematic Approach
• Make things fit together, for safety & efficiency• Standard approaches and COTS solutions, where possible• Integrated power solutions• Minimise self-RFI (EMC), shutdown of non-essential systems• In addition to installation of hardware/software, need to review
& update (maintenance/operational) handover processes, consistent with relevant AUS/NZ HSE Standards.
• Set, update & review priorities, resource allocations & monitor costs.

Future Challenges
• Consolidating on the Development Projects to support the planned Science Operations Centre (SOC);
• Transition to ASKAP Operations; and• Meeting user expectations under a limited
budget.
