LOFAR, the LOw Frequency Array, is an entirely new radio telescope,
that works without any moving parts, though it observes the whole sky
within seconds. At the moment, the telescope is constructed in
the Netherlands
(--> status quo)
and has a diameter of more than 100 km.
German institutes are planning to expand the LOFAR telescope throughout
Germany. This would increase the resolution of the telscope by five times.
LOFAR would then be the world's largest telescope facility, that is linked via fiber optic cable.
The first
german LOFAR-Station at the site of the Effelsberg radio
telescope in the Eifel mountains took up operation in autumn 2007.
Other stations at Garching
(Unterweilenbach), Potsdam
(Bornim), Jülich and in Tautenburg are already financed and will be built up in 2008/2009.
LOFAR grows to a pan-European project. More stations in England, France and Sweden
are financed yet.

To provide a more uniform distribution of the baselines, more
stations near the LOFAR-core in Exloo would be beneficial. Therefore
additional LOFAR-stations near Bremen and Hamburg are considered. One
station consists of a field of 100 antennas and computer hardware for
data communication.
