The Advanced Instrumentation Technology Centre (AITC) provides design, manufacturing and testing capabilities for precision instruments and opportunities for student participation in technical projects at RSAA. It is also home to a research and development program focussing on the next generation of large optical telescopes.
The AITC is creating a new national centre for the Australian space community, connecting researchers and industry partners from around the country and across the globe, and providing a state-of-the-art payload development and systems integration resource.
The new facilities available within the AITC will soon include a 3m diameter by 4m long thermal vacuum chamber that can not only simulate the airless environment of space, but can also heat or cool a test article to realistically test its performance at extreme temperatures. This is useful for space projects, and also needed to test astronomical instruments and components, many of are operated in a vacuum.
The centre will also include a computer-controlled "shaker" capable of exerting acceleration forces of several tons on various instruments under test. This is vital for anything that is going to be launched into orbit, because scientists have to be confident that it can survive the bumpy ride atop a rocket and still work properly when it arrives in space. It can also be very helpful to be able to test the ability of huge telescope parts to withstand the more gentle, but still potentially damaging, process of land transport.
AITC state-of-the-art facilities enable us to ensure that articles and materials to be fabricated, processed, inspected, or tested meet requrements for temperature, humidity, electrostatic discharge, or contamination control. Assembly and test areas and controlled and maintained to cleanliness levels of at least Class 10,000, or better if required.

Electrodynamic vibration test facilities
A 35kN vibration test facility is planned for installation in late 2012. This will offer the ability to simulate a space launch environment for test objects of up to 250kg.
Providing random and sine vibration spectra suited to satellites from nanosat to smallsat classes, this facility will enhance Australia's participation in space systems design and development.
Thermal vacuum chamber
Also planned for future installation is a 3m diameter by 4m long thermal vacuum chamber that can simulate the vacuum conditions of space and heat or cool a test article over a temperature range of -170°C to +80°C, to provide a realistic test bed for its performance.
