Transcript of Background
Background
• The Rothney Astrophysical Observatory (RAO) is operated by the Department of Physics & Astronomy of the University of Calgary
• The RAO was inaugurated on Jan. 7, 1972 • 0.4, 0.5 and 1.8 meter optical telescopes• The RAO is located near Priddis (Alberta), about
30km southwest of the Calgary city center• Current control software is broken
Overall Status
• Decision to use ACS
• U of C grad student hired
• Began porting RAO control software ~May 2005
• Upgrade plagued by numerous problems:
– Lack of Linux Port IO driver
– Kernel module problems with OSes supported by ACS
– Infrastructure and sys admin issues
– Not enough man-power
• Still, we are making progress
Why Use ACS?
• Existing control system coupled too tightly with the Windows-only GUI
• A very strong desire to control the telescope(s) remotely
• Need to have semi-permanent support
Planned Usage of ACS
• Present control system being converted from Windows-only GUI to (non-ACS) C++ classes
• 3rd party libraries distributed with ACS will be used by these classes
• Eventually ACSComponent-derived components will use these platform independent C++ objects as proxies to control the telescope
• Extensive usage of the CDB
Usage to Date
• 3rd party libraries distributed with ACS• ACS logging system• Tool for Automated Tests
Contributions to ACS
• Kernel module to control Linux ports (September)• Security mechanism (sometime in the near future?)
