A new International LOFAR station has been built in Norderstedt, near Hamburg Germany. AstroTec Holding BV, a 100% subsidiary of ASTRON, from now on serves as the contracting partner for new LOFAR stations to be rolled-out.
An MoU was signed at the Hannover Messe (the world’s largest industrial fair) with the University of Hamburg and Bielefeld University.

The roll-out of the station was concluded in December 2014.

AstroTec Holding participates in a joint venture DySI BV. DySI is a spin-off from ASTRON and aiming to use knowledge acquired from the development of LOFAR Big Data systems for commercial applications.

The Polish consortium POLFAR awarded to AstroTec Holding a contract for the design and construction of three International LOFAR stations.
For these stations more than 150,000 individual parts where manufactured, shipped to the station sites and assembled into three beautiful new LOFAR stations located in Bałdy near Olsztyn, in Borówiec near Poznan and in Łazy near Krakow.
2000 m3 of structural parts (EPS) for the LOFAR High Band Antennas waiting to be shipped.
As the stock level of parts was practically zero, several procurement and production runs had to be executed. Due to the effort of a dedicated ASTRON team, batches of new LOFAR components gradually became available. In June 2015 eighteen subbracks where assembled, tested and mounted into three 20 foot ILT containers and shipped consequently to the station sites.
Upon completion of the roll-out the ASTRON commissioning team performed a Site Acceptance Test (SAT) for station Bałdy in August under a bright summer sky and the final station Łazy in October, the latter being covered with 10cm of early fallen snow! All SATs were witnessed by representatives of the station owners and were concluded successfully.
