Virtual Laboratory in European projects EXPReS – a Real-time e-VLBI Radio Telescope - JRA1: Future Arrays of Broadband Radio-Telescopes on Internet Computing (FABRIC) - Grid – VLBI collaboration - Grid Workflow management - Grid Routing RING – Remote Instrumentation in Next- Generation Grids - research project

VLBI is a technique, in which physically independent and widely separated radio telescopes observe the same region of sky simultaneously, in order to generate very high-resolution continuum and spectral-line images of cosmic radio sources. Telescopes are usually separated by thousands of kilometres Data from each telescope are digitally sampled and stored locally, using high-capacity magnetic tape systems and magnetic disk-array systems Data are sent and correlated at the central point (JIVE) The total flow of data into the central processor is approximately Terabytes per single observation, after processing this is reduced to Gbytes. VLab in European projects - EXPReS

EXPReS – the objective is to create a production-level “electronic” VLBI (e-VLBI) service, in which the radio telescopes are reliably connected to the central data processor at JIVE via a high-speed optical-fibre communication network: Single radio telescope is producing a 2.5Gbps of data during e-VLBI observation Up to 16 radiotelescopes can take part in the e-VLBI Aggregate data flow of up to 40 Gbps into the central processor Generating high-resolution images of cosmic radio sources in real-time. VLab in European projects - EXPReS

e-VLBIpilots Current status of the e-VLBI Proof-of-Concept Telescope Network connections. Five telescopes are connected to their NREN, GEANT & ultimately JIVE at 1 Gbps (Jodrell Bank & Cambridge – UK; Westerbork –NL; Torun – PL; Onsala – SE). Arecibo (USA) is connected at 155 Mbps.

Real – time eVLBI correlation on distributed Grid resources: 4 radio telescopes 4 radio telescopes experiment length (2 – 4 hrs) experiment length (2 – 4 hrs) data rate 128 Mb/s per telescope data rate 128 Mb/s per telescope VLab in European projects - EXPReS
