The Square Kilometre Array (SKA) is a Radio Telescope Interferometer array in development in 2012 with receivers in two regions of the world, one centered in Australia and the other in South Africa. Plans are to begin construction in 2019 with observations beginning in part of it in 2022 and construction completion around 2030.

Plans are that it view a wide range of frequencies. SKA-LOW is a planned subsystem aimed at 50MHz-600MHz observation. Its antenna system is called the Low Frequency Aperture Array (LFAA).
