This report describes the reflector support and drive system for a large radio telescope of unconventional design. The telescope consists of a hollow sphere supported in a hydrostatic bearing formed by a concave socket filled with water. A simple system of water pressure pads driven by a positive displacement pump keeps the sphere centered in the socket.
