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.
EXPRESS – FABRIC (cont.)EXPRESS – FABRIC (cont.)
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.
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.
