The Square Kilometer Array (SKA)

The Square Kilometer Array (SKA) is a unique radio telescope being planned by an international consortium. Covering frequencies of 0.15-20 GHz or higher, the SKA will make a revolutionary break from today’s radio telescopes. It willĀ have a collecting area of one square kilometer, making it 100 times more sensitive than today’s best radio telescopes.


Be the first aperture synthesis telescope with multiple independant fields of view; andĀ integrate computing hardware and softwre on a massive scale, in a way that best captures the benefits of these exponentially-developing technologies.
The United States Square Kilometer Array Consortium (US SKA) is a consortium of universities and astronomy-related organizations in the United States who are studying and prototyping technologies under development for the SKA. Please see the members section for a listing of current members of the US SKA. The design being considered by the US SKA consortium is one with a large number (100-1000) stations, each consisting of some number of antenna elements. This “Large-N” concept offers considerable advantages over traditional designs, including superb image fidelity and dynamic range, multibeaming capabilities, instantaneous imaging, improved interference suppression, flexibility, and expandibility. For information on becoming a member of the US SKA consortium, please see membership.

For more information about the project, please see the about section, as well as the documents section which contains relevant reports and publications. Also browse recent news and view past and upcoming meetings.

Other members of the international consortium include teams from Australia, Canada, China, Europe, and India. Please see the links section to learn about these designs.
