The Nançay radio astronomy observatory and associated laboratories are developing the concept of a “Super Station” for extending the LOFAR station now installed and operational in Nançay. The LOFAR Super Station (LSS) will increase the number of high sensitivity long baselines, provide short baselines, act as an alternate core, and be a large standalone instrument. It will operate in the low frequency band of LOFAR (15–80 MHz) and extend this range to lower frequencies. Three key developments for the LSS are described here: (i) the design of a specific antenna, and the distribution of such antennas; (ii) at small-scale (analog-phased mini-array); and (iii) at large-scale (the whole LSS).
LʼObservatoire de Nançay et des laboratoires associés développent un concept de “Super Station” afin dʼétendre les capacités de lʼactuelle station LOFAR installée à Nançay. La Super Station LOFAR (LSS) augmentera le nombre de longues bases interférométriques sensibles, fournira de nouvelles bases courtes, formera un cœur alternatif à LOFAR et constituera un nouvel instrument autonome. Il opèrera dans la bande basse de LOFAR (15–80 MHz) et étendra cette bande à plus basses fréquences. Trois études clefs sont décrites ici : (i) La conception dʼantennes spécifiques, et leur distribution ; (ii) à petite échelle (dans un mini-réseau phasé analogique) ; et (iii) à grande échelle (réseau LSS).
