dc.description.abstract | The design and development process for the Square Kilometre Array (SKA) radio telescope’s Low Frequency Aperture Array component was progressed during the SKA pre-construction phase by an international consortium, with the goal of meeting requirements for a critical design review. As part of the development process a full-sized prototype SKA Low ‘station’ was deployed – the Aperture Array Verification System 1 (AAVS1). We provide a system overview and describe the commissioning results of AAVS1, which is a low frequency radio telescope with 256 dual-polarisation log-periodic dipole antennas working as a phased-array. A detailed system description is provided, including an in-depth overview of relevant sub-systems, ranging from hardware, firmware/software, calibration and control sub-systems. Early commissioning results cover initial bootstrapping, array calibration, stability testing, beamforming and on-sky sensitivity validation. Lessons learned are presented, as well as future developments. | en_GB |
