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 10-100 Terabytes per single observation, after

processing this is reduced to 10-100 Gbytes.

VLab in European projects - EXPReSVLab 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.
