15m XDM Radio Telescope

The eXperimental Development Model (XDM) is a 15-m diameter radio telescope antenna of innovative design intended to reduce antenna construction cost per square metre and bring it close to that needed to make Square Kilometre Array (SKA) affordable. IST Holdings were the prime contractors building XDM at Hartebeesthoek.

The Karoo Array Telescope (KAT) will be used to test technology leading up to development of the Square Kilometer Array (SKA). The XDM is a testbed prototype for KAT.
