Metsähovi participated in a 3-year project NEXPReS concluded in June


Metsähovi Radio Observatory participated in a three year project NEXPReS (Novel EXplorations Pushing Robust e-VLBI Services) concluded at the end of June, 2013.

The aim of NEXPReS was to eliminate the distinction between traditional disk-based VLBI and real-time e-VLBI by incorporating elements of each into every observation by the European VLBI Network (EVN).

Metsähovi's part in NEXPReS was to develop a high-bandwidth, high-capacity networked storage system. The main design purpose of "Flexbuff" is data buffering at the telescope stations, but it also addresses the need for long-term storage and correlator buffering. Research of this type of system was previously carried out on custom-built storage systems, but work with NEXPReS has proven that similar results can be accomplished with commercial, off-the-shelf components.

NEXPReS project was funded by the European Union's Seventh Framework Programme under Grant Agreement RI-261525. It was comprised of 15 partner institutes in eleven countries and coordinated by the Joint Institute for VLBI in Europe (JIVE) in the Netherlands.
