Keynote: The Square Kilometre Array
summary
The Square Kilometre Array builds two separate telescopes: a mid‑frequency dish array sited in South Africa and a low‑frequency dipole array in Western Australia, with 197 dishes and about 130,000 dipoles planned. Precursor MeerKAT (64 dishes) already produces novel images of the Galactic center and unexpected AGN jet features. Raw links push ~10 Tb/s per site, post‑processing yields roughly 300 PB/year per telescope; central signal processing runs on FPGAs, science pipelines on GPUs, synchronized via White Rabbit.
