eVLBI fringes from down under
| Submitter: | Zsolt Paragi (for Arpad Szomoru) |
| Description: | On 14th of August we obtained the first fringes between two Australian telescopes, correlated in real-time on the EVN MarkIV correlator at JIVE. The telescopes involved were Mopra and ATCA (single dish). Data rates were 128 and 256 Mbps, the transport protocol used was a locally made version of Circuit TCP (basically TCP without congestion control). The data were converted at the stations on-the-fly to Mark5B format and played back on Mark5A+ units at JIVE. A few people contributed very significantly to achieve this milestone: Chris Phillips worked on data conversion and interface, Mark Kettenis implemented Circuit TCP, Paul Boven and Shaun Amy took care of the many networking issues at JIVE and ATNF. And of course we could not have done this without the support of our friends at the NRENs, AARNET, SURFNet and CANARIE. |
