The Aperture Array Verification System 1: System overview and early commissioning results
P. Benthem, R. Wayth, E. de Lera Acedo +51
The design and development process for the Square Kilometre Array (SKA) radio telescope, the Low Frequency Aperture Array component, was progressed during the SKA pre-construction…
On-sky calibration of a SKA1-low station in the presence of mutual coupling
Josef Borg, Alessio Magro, Kristian Zarb Adami +3
This paper deals with the calibration of the analogue chains of a Square Kilometre Array (SKA) phased aperture array station, using embedded element patterns (one per antenna in th…
Signal Processing Firmware for the Low Frequency Aperture Array
Gianni Comoretto, Riccardo Chiello, Matt Roberts +22
The signal processing firmware that has been developed for the Low Frequency Aperture Array component of the Square Kilometre Array is described. The firmware is implemented on a d…
GPU-Powered Coherent Beamforming
Alessio Magro, Kristian Zarb Adami, Jack Hickish
GPU-based beamforming is a relatively unexplored area in radio astronomy, possibly due to the assumption that any such system will be severely limited by the PCIe bandwidth require…
Suitability of NVIDIA GPUs for SKA1-Low
Alessio Magro, Kristian Zarb Adami, Steve Ord
In this memo we investigate the applicability of NVIDIA Graphics Processing Units (GPUs) for SKA1-Low station and Central Signal Processing (CSP)-level processing. Station-level pr…
MITEoR: A Scalable Interferometer for Precision 21 cm Cosmology
Haoxuan Zheng, Max Tegmark, Victor Buza +34
We report on the MIT Epoch of Reionization (MITEoR) experiment, a pathfinder low-frequency radio interferometer whose goal is to test technologies that improve the calibration prec…
