4th International VLBI Technology Workshop (IVTW)

23 to 26 November 2015


The Fourth International VLBI Technology Workshop will be hosted by the Institute for Radio Astronomy and Space Research at Auckland University of Technology, Auckland, New Zealand. It will take place from Monday 23 to Thursday 26 November in AUT’s newest venue – the Sir Paul Reeves Building.

Sunday 22

5.00 – 7.00 pm Icebreaker reception early evening with light refreshments.  Venue is Level 4, Sir Paul Reeves Building (WG), AUT City Campus.

Monday 23 to Thursday 26

4th IVTW

Thursday 26

The day's program will include a bus trip to our Warkworth Observatory and to Leigh.  Pakiri Hill near Leigh was one of two sites used by John Bolton and Gordon Stanley during their Cosmic Noise Expedition in 1948.

The International VLBI Technology Workshops have evolved from the highly successful 10-year series of International e-VLBI workshops. The expanded scope of the technology workshops aims to encompass all areas of hardware or software development relevant to VLBI. In particular, though, development of global e-VLBI still features prominently and with it the close collaboration VLBI has developed over the years with national and international research network providers.

The fourth Workshop in this series will feature major VLBI topics, such as VLBI Global Observing System (VGOS) and global VLBI developments, receivers, digital backends and recording equipment, e-transport and correlators, as well as mm-VLBI and space VLBI.
