SKAO Director General Phil Diamond visited the MRO on a recent
visit to Australia and took the above photo from the middle of the
Aperture Array Verification System 2.
AAVS2, located at the Murchison
Radio-astronomy Observatory, is a testbed to evaluate the performance
of antennas before construction of the full SKA-Low commences. AAVS2 is
an array of 256 SKALA4.1 antennas distributed in a semi-random (but
carefully chosen!) layout over a circular station area, with maximum
spacing of 38 metres. The SKALA4.1 antenna is of dual linear
polarisation and all antennas in the station have the X polarisation
oriented E-W and Y polarisation oriented N-S.
A previous ADAP has shown the array elements pictured from above.
