ASKAP is designed to be a high speed survey instrument with high dynamic range. This requires an extremely wide field-of-view interferometer with Phased Array Feeds (PAFs). The PAF has a total of 188 elements, 94 in each of two polarizations.
The specification for ASKAP is:
A total collecting area of approximately 4,000 square metres, from 36 antennas each 12 metres in diameter
System temperature less than 50 K
Frequency range from 700 MHz to 1.8 GHz
300 MHz instantaneous bandwidth
36 independent beams, each of about 1 square degree, yield overlapping to a 30 square degree field-of-view at 1.4 GHz
Maximum baseline of approximately 6 km
Full cross-correlation of all antennas
Possible remote array station capability located in NSW, approximately 3,000 km from the core site.
Maximising science impact with the SKA in Australia April 2016: The second annual OzSKA meeting was held to discuss developments in the Square Kilometre Array (SKA) – with a focus not only on astronomy, but also technological development and the evolution of the SKA Organisation itself.
Parkes telescope granted 'SKA pathfinder' status April 2016: CSIRO’s iconic Parkes radio telescope has been granted the status of ‘SKA pathfinder’ by the Square Kilometre Array Organisation, on the basis of its role in testing innovative new receiver systems for radio astronomy.
