Baseband processing, e-VLBI, and SKA simulations

This presentation discusses the applications of baseband processing, e-VLBI technology, and SKA simulations in strengthening Australia's bid for the SKA project. It highlights the development of baseband recording technologies, software correlators, and other processing technologies for VLBI, as well as the collaboration with international partners. The talk also covers the cost estimation of the SKA project and the coordination efforts with the Swinburne Science Working Group.

Presentation Transcript

  1. Baseband processing, e-VLBI, and SKA simulations Steven Tingay Swinburne University of Technology MNRF Symposium, 8 June, 2004

  2. Swinburne MNRF Program Provide facilities that will benefit the Australian community now, strengthen Australia’s bid for the SKA, and make a significant contribution directly to the international SKA project • Baseband processing applications, SKA prototyping and demonstration • Pulsar timing using PC clusters (Matthew Bailes talk) • e-VLBI. Demonstrates : • baseband recording/buffering; • real-time data transport and correlation on long baselines; • Data archiving, sensitive wide-field imaging; • e-VLBI is the SKA without the collecting area or bandwidth • SKA simulations • Development of MIT/Haystack simulator for SKA • Collaboration in EU FP6 proposal • Involvement in SSWG • SKA cost estimation

  3. e-VLBI • Develop baseband recording technologies for VLBI; • Develop software correlators and other baseband processing technologies for VLBI; • Collaborate with ATNF and University of Tasmania – use multi-Gbps links: • 5 point plan over next 3 – 4 years (See Tasso Tzioumis); • Demonstration of e-VLBI this year; • Gbps e-VLBI within 12 months between some antennas; • Real-time e-VLBI by 2007 using broad-band ATCA correlator • Well-developed science case

  4. Recent highlight – global disk-based and e-VLBI experiment • Nine antennas in two seven antenna experiments in April 2004 – most ambitious technical demonstration of disk-based VLBI: • Australia: ATCA, Mopra, Parkes, Hobart, Tidbinbilla, Ceduna • USA: Pie Town (VLBA) • South Africa: Hartebeestoek • Japan: Kashima • Three different disk-based VLBI recording systems: • PC-EVN • MkV (two varieties) • K5 • Software correlation in near real-time • Fringes between 4 Australian antennas • Software correlation of full experiment on Swinburne supercomputer

  5. SKA simulations • Provide supercomputing resources and software development to the national and global SKA simulation communities: • ATNF (array configuration studies); • University of Melbourne (EoR simulations) • MIT/Haystack (simulation code) • Oxford (science simulations) • EU FP6 (all aspects of SKA simulation – will find out in next few months) • … • … • … • Coordinated by SSWG (reports to the ISSC - chaired by Tingay)

  6. SKA cost estimation • Collaboration between Swinburne University, SKA International Project Office, and International Engineering Management Team; • Standard definition of SKA engineering subsystems; • Estimate the construction and operations cost for the different SKA configurations; • Include operational costs, software costs, etc; • Implemented as an interactive software tool for general or expert use; • To be reviewed at Penticton meeting next month.
