Abstract
The Square Kilometer Array (SKA), with its unprecedented large radio wave collecting area, will be 50 times more sensitive than any imaging radio telescope array previously built and be able to survey the sky 10000 times faster. The SKA project is now moving towards the start of procurement phase and construction activities. Verification Systems and Precursors on the SKA sites are already showing promising results. This paper will focus on the high sensitivity goals and how these are achieved by the SKA design.
