  3. You are here Low data rate astronomy Transatlantic real-time fringes Project Timeline

  4. January 2004: Disk buffered eVLBI session: • Three telescopes at 128Mb/s for first eVLBI image • On – Wb fringes at 256Mb/s • April 2004: Three-telescope, real-time eVLBI session. • Fringes at 64Mb/s • First real-time EVN image - 32Mb/s. • September 2004: Four telescope real-time eVLBI • Fringes to Torun and Arecibo • First EVN, eVLBI Science session • January 2005: First “dedicated light-path” eVLBI • ??Gbyte of data from Huygens descent transferred from Australia to JIVE • Data rate ~450Mb/s eVLBI Milestones (since 2nd EVN-NREN Meeting)

  8. Next Six Months • Objectives • Induction of Jodrell/Cambridge and Medicina when high speed links are ready. • Expansion of the array to seven telescopes: Ar, Cm, Jb, Mc, On, Tr, Wb • Higher data rates > PoC target of 512Mb/s. • Correlator/Mark5, eVLBI robustness issues. • eVLBI Logistics: FS and correlator-control coordination for smooth operations. • Alternative protocol development and testing - viz. work underway at Jodrell Bank and JIVE • Integration of Haystack e-VLBI products: VSI-E, network monitoring tools. • Transatlantic eVLBI and dedicated light paths.

  9. Next Six Months • Dates for Scheduled e-VLBI tests and demos • 10 Feb - (not Onsala) • 11 March - (science demo) • 24 March • 28 April • 26 May • 7th July (not Onsala)

  10. Science Demo – 11 March • Cm, Jb,On, Wb, Tr, (Mc?) • Continuum source • 128Mb/s • First trial of “dynamic scheduling”: • Test several sources for suitability • Observe brightest ….not possible with standard VLBI
