CSIRO 'hot rods' old telescope
CSIRO has helped transform the University of Sydney's radio telescope into a world-class instrument, and along the way has learned lessons for its own ASKAP (Australian SKA Pathfinder) telescope.
Both telescopes will help demonstrate Australia鈥檚 technological expertise in its bid to host the world鈥檚 largest and most advanced radio telescope 鈥� the Square Kilometre Array (SKA).
The University of Sydney runs what was the Molonglo Observatory Synthesis Telescope (MOST) near Canberra. It contracted CSIRO to help develop signal-processing systems 鈥� a filterbank and correlator 鈥� to dramatically boost the telescope鈥檚 performance.
The upgrade has made the telescope more flexible, three times more sensitive, with ten times more bandwidth [up from 3 MHz to 30 MHz], and able to make better-quality images of objects in space.
鈥淭his project has given our telescope a whole new capability,鈥� says Professor Anne Green of the University of Sydney, who led the process.
鈥淚t looks the same, but under the bonnet it鈥檚 been born again.鈥�
And the 鈥渘ew鈥� telescope has a new name: SKAMP (the Square Kilometre Array Molonglo Prototype).
The formal handover of the new signal-processing systems recently took place at the University of Sydney.
The knowledge CSIRO has gained during the course of this project has been applied to the design of the digital systems for its own ASKAP telescope, which is now under construction in Western Australia. Much of the SKAMP contract was carried out by the ASKAP Digital Systems team.
鈥淲hat we鈥檝e learned over several years will now allow us to dramatically shorten our design cycle for ASKAP's digital systems, as well as potentially feed into future development work that will be required for the SKA,鈥� says CSIRO SKA Director, Dr. Brian Boyle.
